OUR 40 YEARS OF 

RACING HERITAGE! 

Back in the late 60s the Cloyes engineering team, headed by Mr. Bob Bub, 

saw the surging popularity of the weekend racer and set out to develop 

products to service the race crowd. In 1970, Mr. Bub and his team 

developed and marketed the very fi rst True ® Roller Speed set. With its 

balanced and multi-keyway sprockets, hand-matched with a new chain 

featuring solid bushing type rollers, the 

True ® Roller set was designed for racing 

and changed the timing game forever. 

In this 1972 letter, Junior Johnson 

attributes the new Cloyes True ® Roller 

set to aiding in their win at Atlanta (with 

Bobby Allison driving). They won 10 

races that year. The Cloyes name 

soon became known for the best racing 

timing set in the U.S. 

As racing grew both professionally and at the enthusiast level, the 

Cloyes line of High Performance cam drives grew with it. Over the 

years, Cloyes engineers have collaborated on projects with some of 

the legendary names in racing – names like Hendrick, Roush, Yates, 

Dorton, Mondello, as well as the major racing programs at GM, Ford, 

Mopar, and Mercury Marine. 

As competitors came into the market with copy-cat speed sets, 

we needed to take it up a notch. In 1992, Cloyes developed and 

patented the Hex-A-Just ® True ® Roller. Hex-A-Just ® was an industry 

fi rst, allowing an engine builder to easily adjust valve timing with the 

turn of an allen wrench, saving hours on the dyno or at the track. 

We soon added our Quick Button 2 pc Timing Cover allowing easy 

access to the timing adjustment. We now have over fi ve patents 

that compliment our Hex-A-Just ® system, which remains the premier 

adjustable timing set on the market. 

Cloyes Wins Indy!! Cloyes helped power Arie Luyendyk’s winning car at the 1997 Indianapolis 500. 

This was the fi rst race featuring the Olds Aurora racing engine. Because of our close ties to GM, we 

were asked to make the timing set for their entries in the new Indy Racing League. 

Until its demise in 2006, all the Pontiac Firebirds running in the IROC Series (International Race of 

Champions) were equipped with a Cloyes True ® Roller set. More recently, we’ve made special timing 

sets for the prototype engines you see running the 24 Hour races at Lemans, Sebring and Daytona. 

Over the past 40 years, it has been our innovation and attention to detail that has set us apart from 

the rest. Today, Cloyes custom race products are in winning engines at all racing levels across the 

country and around the world. We continue to work for you, the professional racer. We know what’s 

on the line when you head to the track. We are committed to continue providing the unmatched quality 

and performance you expect to keep you ahead of the competition! 

We thank you for your continuing support . . .40 years and counting!

“We have been using Cloyes Quick Adjust Timing sets with their Premium 

chains and cam sprockets in our big block Ford blown alcohol injected 

engines for three years. Our monster trucks put these components to the 

test as we run high temperatures in our motors during the 90 second to 3 

minute freestyle competitions and during racing. In the 27 years we have 

been racing monster trucks we haven’t come across a roller chain set that 

lasts as long with little stretch as Cloyes. We also like the adjustability of 

the cam sprocket which enables us to dial our cam degree in easier than 

other brands. Based on our experience and compared to other products 

Cloyes is your best bet for any application be it performance or street 

vehicles.” 

Michael Vaters 

Black Stallion Monster Truck Racing 

“Producing over 1500 reliable HP with a traditional Pontiac engine 

is a challenge. I have been utilizing the Cloyes True Roller Timing 

sets on these engines for 12 years without a single timing system 

failure. This is with open valve spring pressures in excess of 1000 

PSI and engine speeds in excess of 8000 RPM. In a match race 

environment, consistent performance and reliability are paramount. 

We have never had a cam timing related issue with the Cloyes 

chain drive.”

FEATURED PRODUCT 

GM’s LS Engines 

TRUE ® ROLLER SETS FOR ALL YOUR LS NEEDS! 

We start with sprockets machined from premium billet steel on state-of-the-art CNC equipment. Both 

sprockets are then induction hardened and oil-quenched using our in-house multi-stage heat treat 

process. Our sprockets are made “oversized” to eliminate the chain slack found in the OE and 

other aftermarket sets. The cam sprocket is machined for and includes a captured thrust bearing to 

reduce friction. Our Premium True ® Roller chains feature superior strength with full roller action. Side 

plates are cut and shaved from high strength steel and heat-treated for maximum fatigue resistance. 

The .250” rollers are “cold rolled” and hardened to exacting standards increasing load and RPM 

capabilities. All our LS sets are hand-matched at our manufacturing facility to qualify center distance 

and run out. This is a Cloyes Exclusive - no one else in the industry takes the time and attention to 

detail to ensure you get the very best custom set in each and every box. 

We offer LS sets in our patented Hex-A-Just ® series allowing easy timing adjustment of +/- 6º, as well 

as in our Race Billet series which are available with three or nine keyways. 

New Coverage for Raised Blocks and also an EXTREME DUTY Race Chain! 

LS sets now available with increased center distance for the RHS and other .390 raised blocks. 

Also new this year, all our LS sets are available with the well-known racing chain currently being used 

by the leading 24 hour endurance teams . . . 

Cloyes True ® Roller “Z” Chain 

The “Z” chain is the preferred extreme racing option offering unmatched strength and durability for 

the LS team looking for all-out racing performance. The “Z” chain is standard on our raised cam LS 

sets and available as an upgrade on all LS applications. YOU WON’T FIND BETTER!

FEATURED PRODUCT 

Hex-A-Just ® 4.6L 2V 

Increase both torque and horsepower with improved 

cam timing balance. This engine is unique in that 

the individual bank valve trains are controlled 

by two separate chains and cam sprockets. The 

patented Cloyes Hex-A-Just ® system allows you to 

quickly make adjustments to balance the right and 

left banks and meet any custom cam specifi cations 

required to maximize your engines output. 

This is not a two-piece sprocket design. 

This exclusive Hex-A-Just ® product is a one-piece 

sprocket design that functions in the same way 

as the OE confi guration. It utilizes a stainless steel 

adjuster plate of specifi ed hardness and thickness 

that replaces the OE cam sprocket washer. 

Wide tolerances are an inherent flaw with any mass 

produced OE part. This is corrected by the fact that 

our sprockets are precision machined from premium 

billet steel on our state-of-the-art CNC equipment. 

Special care is taken to tolerance critical features (bore 

fitment, keyway fitment, timing angle, etc.) for each high 

performance sprocket manufactured. All sprockets 

are then induction hardened and oil-quenched using 

our in-house multi-stage heat treat process. 

The dynamometer graph shows noticeable torque 

and horsepower gains as a result of corrected 

camshaft positions from a simple bolt-on. Your 

additional fi ne tuning results in maximum gains. 

• Patented Hex-A-Just ® allows +/- 4° 

• Induction Heat Treated, Billet Steel Sprockets 

• Precision tooth profile for ideal chain mesh 

• Precision machined keyway and bore fitment 

• Exclusive light, fine finished performance chains 

2V - Full Kit - Includes ALL the timing components; two Hex-A-Just ® adjustable billet steel cam 

sprockets, billet steel crank sprocket, two fi ne fi nish chains, all guides and tensioners. 

2V - Upgrade Kit - Everything in this kit is an upgrade from OE; two Hex-A-Just ® adjustable billet 

steel cam sprockets, billet steel crank sprocket, two fi ne fi nish chains. 

2V - Sprocket Kit - Includes the two Hex-A-Just ® adjustable billet steel cam sprockets.

FORD 4.6L MODULAR ENGINES 

Hex-A-Just ® 4.6L 4V 

As with the 2V, the 4V has the same potential 

to increase both torque and horsepower 

with improved cam timing balance. This 

engine is like the 2V in that the individual 

bank valve trains are controlled by two 

separate primary drives, but in addition 

the 4V utilizes secondary drives to control 

the intake cams. The patented Cloyes 

Hex-A-Just ® system allows you to make 

the needed adjustments to customize 

your valve train settings. Our primary 

cam sprockets allow you to balance the 

banks, while the 9-keyway secondary cam 

sprockets give you the tools required to 

adjust exhaust cam to intake cam overlap. 

This is not a two-piece sprocket design. 

This exclusive Hex-A-Just ® is a one-piece 

primary sprocket design that functions in 

the same way as the OE confi guration. 

It utilizes a stainless steel adjuster plate 

of specifi ed hardness and thickness that 

replaces the OE cam sprocket washer. 

All of our sprockets are machined from 

premium billet steel on our state-of-theart 

CNC equipment. Special care is taken 

to tolerance critical features (bore fitment, 

keyway fitment, timing angle, etc.) for each 

high performance sprocket manufactured. 

All sprockets are then induction hardened 

and oil-quenched using our in-house multistage 

heat treat process. 

• Patented Hex-A-Just ® allows +/- 4° 

• Induction Heat Treated, Billet Steel Sprockets 

• 9-keyway secondary cam sprockets allow +/- 4° 

• Secondary sprockets adjustable in 1° increments 

• Precision tooth profile for ideal chain mesh 

• Precision machined keyway and bore fitment 

• Exclusive light, fine finished performance chains 

• Upgraded secondary racing roller chains 

Our one-piece billet steel cam sprocket design, 

used on both 2V and 4V applications, works 

identical to the OE confi guration by using our 

custom adjustable washer. 

4V – Upgrade Kit 

Everything in this kit is an upgrade from OE; two Hex-A-Just ® adjustable billet steel primary 

cam sprockets, two 9-keyway billet steel secondary cam sprockets, two 1-keyway billet steel 

secondary cam sprockets, billet steel crank sprocket, two fi ne fi nish primary chains, two 

upgraded secondary roller chains.

ADJUSTABLE SPEED SETS 

Adjust your Valve Timing with Confidence! 

The Cloyes patented Quick Adjust ® True ® Roller Speed Sets keeps you ahead of the 

competition by offering a new way to adjust cam timing up to +/- 6 degrees. Just loosen the 

six bolts around the cam sprocket, insert the patented Quick Adjust ® tool, and tune your way 

to faster times. Sprockets are machined from premium billet steel on our state-of-the-art 

CNC equipment. Both sprockets are then induction hardened and oil-quenched using our 

in-house multi-stage heat treat process. Our Premium True ® Roller chain features superior 

strength with full roller action. Side plates are cut and shaved from high strength steel 

and heat-treated for maximum fatigue resistance. The .250” rollers are “cold rolled” and 

hardened to exacting standards increasing load and RPM capabilities. All Quick Adjust ® sets 

are hand-matched at our manufacturing facility to qualify center distance and run-out. An 

additional feature on Chevrolet applications is the Cloyes patented “cheater” sprocket tooth 

profile that provides improved chain wrap and smoother transition. Get serious about going 

fast with this unbeatable combination - Cloyes and Quick Adjust ® !

Cloyes Tech Tip 

When making cam timing adjustments with a Cloyes 

Hex-A-Just ® set you must LOOSEN THE CAM BOLTS 

AND RELEASE THE CAMSHAFT LOAD! 

The Industry Standard in Adjustable Cam Timing. 

An industry breakthrough when introduced in 1992. Since then the accuracy and simplicity 

of our Hex-A-Just ® system remains unmatched by our competitors. The Hex-A-Just ® 

True ® Roller Set is infinitely adjustable to +/- 6 degrees. No machining required and no 

fumbling with offset bushings. Simply dial in your cam timing with the turn of a wrench, 

then tighten the cam bolts to lock the cam position in place. When combined with our 

Quick Button Two Piece Timing Cover (opposite page), this Cloyes patented technology 

will save you hours of valuable set-up time. Sprockets are machined from premium billet 

steel on our state-of-the-art CNC equipment. Both sprockets are then induction hardened 

and oil-quenched using our in-house multi-stage heat treat process. Our Premium True ® 

Roller chain features superior strength with full roller action. Side plates are cut and 

shaved from high strength steel and heat-treated for maximum fatigue resistance. The 

.250” rollers are “cold rolled” and hardened to exacting standards increasing load and 

RPM capabilities. An additional feature on Chevrolet applications is the Cloyes patented 

“cheater” sprocket tooth profile that provides improved chain wrap and smoother transition. 

Whether your destination is the street or the track, Hex-A-Just ® will get you there faster!

CENTER DISTANCE & HAND MATCHING 

What is Center Distance 

Center Distance (or CD) is the 

measurement from the center of the 

camshaft to the center of the crankshaft. 

Accurately matching your timing set 

to the center distance of your engine 

will determine the performance and 

longevity of your timing set. 

CD = MOS - (CRANK DIA./2 + CAM DIA./2) 

Hand Matching . . . A Cloyes Exclusive! 

All of our premium Race sets (Hex-A-Just ® , 

Quick Adjust ® , Race Billet, and Original 

True ® ) are hand-matched at the Cloyes 

manufacturing facility by trained personnel 

to qualify center distance and runout. Each 

and every set is measured, by hand, under 

a predetermined load to determine the exact 

center distance of each set. It is this attention 

to detail that sets Cloyes apart from the rest 

of the pack. If you are ordering an undersize 

set, put your confi dence in the fact that these 

sets are also hand matched to make sure you 

are getting the precise center distance that 

your align honed engine needs. 

Reduced Center Distance Sets! 

Look for the ▼ in the application listings on pages 6 through 17. 

Many of our premium Race sets (Hex-A-Just ® , Quick Adjust ® , Race Billet, Original 

True ® ) are available in reduced center distance of -.005 and -.010. This is noted in the 

application listings by the symbol ▼ next to the part number. 

To order a reduced center distance set: 

Simply add -5 or -10 to the part number. For example, 9-3100A-5 or 9-3100A-10 

15 Under 

We sometimes have limited supply of .015 reduced center distance sets for SB Chevy, SB 

Ford, and SB Chevy Rocket. Contact tech for details. 

Aluminum Block 

Given the unique circumstances of certain aftermarket aluminum blocks, Cloyes can 

custom match your timing set “oversized” to accommodate material expansion.

TECH INFO - TIMING CHAINS 

The racing world has different levels of performance and the same is true of the performance 

parts world. There are different levels of speed sets also, and it is important to match the set 

to your needs. As a general rule, you want to upgrade your timing set as you upgrade the 

rest of your valve train components. Within our own product line, we offer two different levels 

of speed sets - STREET and RACE. The factors that separate them are sprocket material, 

heat treatment, chain type and level, matching, and adjustability. See page 32 for a quick 

reference feature comparison. 

all ChaINs aRE NOT CREaTED EQUal 

Probably the most critical part of your timing set is the Timing Chain. Key requirements 

to a quality chain are the component materials and the manufacturing processes. Each 

chain component: pin, bushing, roller, and link perform a specifi c function and therefore 

require a particular material and heat treatment for each of their individual needs. Each 

component is designed to provide excellent wear properties as well as ductility to endure 

shock loads. This balancing of both hardness and ductility can only be accomplished by 

controlled manufacturing processes. 

SEAMED vs. SEAMLESS ROLLERS 

This seemingly endless and age-old debate really has no merit. The fact is, it doesn’t 

matter if a roller is seamed or seamless as long as the proper material, heat treatment, and 

manufacturing processes are implemented. Our standard Street True ® Roller chain, which 

we manufacture with seamless rollers, has proven to be an excellent entry level performer. 

The Cloyes Premium True ® Roller chain, which has seamed rollers and is used on all our 

premium race sets, is racing and winning at tracks across the country and around the world. 

The extremely high-end Cloyes “Z” chain, a new option on our LS applications, also has 

seamed rollers and is being used by many of the leading 24 hour endurance teams. So in 

conclusion, it’s less about the seamed or seamless roller, but more about the material used, 

the manufacturing processes, and a commitment to quality. 

MATCHED vs. UNMATCHED - WHICH DO YOU PREFER 

Another often asked question is about “chain defl ection”. The illustrations below display 

typical chain defl ection (in inches) on a mass-produced OE design vs. the chain defl ection 

on a hand-matched Cloyes True ® Roller set.

ADJUSTING YOUR VALVE TIMING 

Why Advance or Retard Valve Timing 

Adjusting your valve timing gives you the ability to customize your torque and power curves 

to optimize your desired engine output for your specific application needs. 

ADVANCED TIMING = MAXIMUM TORQUE AT LOW RPM 

Recommended for towing, performance street driving, and drag racing with 

automatic transmissions. 

RETARDED TIMING = MAXIMUM TORQUE AT HIGH RPM 

Recommended for circle track, drag racing with manual transmissions and other 

all-out racing applications. 

How to Advance or Retard Valve Timing 

Cloyes offers several different options to adjust your valve timing: 

HEX-A-JUST ® 

With the simple turn of an allen wrench or fuel 

pump eccentric, our patented Hex-A-Just ® 

systems allow you to infinitely adjust valve 

timing within a window of + / - 6 degrees. 

QUICK ADJUST ® 

Another Cloyes patented and innovative way to 

adjust your valve timing. By simply loosening 

the six fasteners and using the supplied tool 

you can infinitely adjust valve timing within a 

window of + / - 6 degrees. 

MULTIPLE KEYWAYS 

Use our three or nine keyway crank sprockets for incremental adjustments

TECH INFO - KEY TERMS 

Key Terms 

center distance - The calculated distance between the center of the crankshaft and 

the center of the camshaft when installed on the engine block. See page 28 for more 

info. 

timing set center distance - The calculated distance between the center of the crank 

sprocket and the center of the cam sprocket with regard to chain pitch and tooth count. 

runout - The amount of linear variation as a timing set rotates. Excessive runout will 

negatively impact performance. 

Cloyes exclusive hand matching - Cloyes process that qualifies our premium race 

sets with respect to center distance and runout. The center distance is matched to 

your specific application and runout is minimized by tedious quality standards. See 

page 28 for more info. 

custom center distance set – This can be an undersized set for align honed blocks 

or any custom size to match a customer’s block measurement. See page 28 for more 

info. 

oversized sprockets - Unique Cloyes manufactured process that allows Cloyes to 

achieve correct center distance on particular sets or applications. This is especially 

important for achieving proper fitment for optimum performance. 

cheater tooth profile - US Patented tooth profile by Cloyes under Patent # 5,848,948 

which provides improved chain wrap, complete distribution of torque loads, and 

accommodates the components as the system wears with use. 

matched gear set - Cloyes process that qualifies a gear set with respect to center 

distance, correct backlash, and runout. 

induction hardened - Cloyes process that heat treats the teeth of a sprocket without 

affecting the hub/web portion of the part. The advantage is a hardened wear surface 

where the chain makes contact, yet a ductile hub/web that can withstand shock loads. 

captured needle thrust bearing - Enclosed bearing that is accommodated by specific 

sprockets for the purpose of enduring thrust loads from the valve train. This type of 

bearing minimizes frictional losses between the cam sprocket thrust surface and the 

front of the block, and also alleviates wear issues. 

thrust washer – Frictional surface part that functions as a wear resistance between 

the cam sprocket thrust surface and the front of the block. Our washers are available 

in hardened spring steel and bronze for specific purposes. 

rollerized cam button – An assembled part that contains a thrust bearing for the 

purpose of setting cam endplay. This part is constructed using heat treated billet and a 

premium thrust bearing.

Certain applications available with Single Roller Chain, check full listings for details. 

So which do you need 

Several factors to consider - most importantly your specific use or 

application and the rest of your valve train components. As a general rule, as 

you step up your cam/valve train combo, you also want to upgrade your 

timing drive. Then just decide how much adjustability you want. 

If unsure, contact your engine builder or our Tech Line.
