HDX PERFORMANCE CLUTCHES 

GREAT DRIVEABILITY AND PERFORMANCE TO 450 HORSEPOWER 

The basic RAM concept of clutch performance is simple: Increased clamp pressure is the single most 

effective way to manage high horsepower or load, especially in street driven performance cars. We purpose 

build RAM HDX pressure plates with 30% more clamp pressure than stock. The second important feature is 

smooth, chatter free operation, which we achieve with premium organic composite disc friction material. 

Also, HDX discs feature our exclusive 8-spring hub assembly for added load capacity.

POWERGRIP CLUTCHES 

MUSCLE CAR PERFORMANCE TO 550 HORSEPOWER 

As power levels move up to and beyond 500 horsepower. RAM POWERGRIP meets the challenge with a 

combination of organic and metallic disc friction surfaces that effectively increase the clutch capacity to the 

550 horsepower level. The 8-spring hub is equipped with RAM POLYCOIL damper springs encapsulated in 

polyurethane. This spring can handle three times the shock load of just the coil spring, and is standard in all 

RAM competition discs. The RAM Competition pressure plate in this kit provides 30% more clamp pressure 

than stock, and meets SFI specifications. At this high level of performance RAM POWERGRIP provides 

Characteristic Barometer surprisingly good driving characteristics with smooth,

POWERGRIP HD CLUTCHES 

STREET AND COMPETITION PERFORMANCE TO 650 HORSEPOWER 

POWERGRIP HD is a true "strip/street" competition clutch system that can handle the rigors of weekend 

racing and spirited street driving. This system has the same components as standard POWERGRIP above 

with the exception that the disc friction surfaces are both sintered iron. Sintered iron provides a degree of 

slippage on vehicle launch to prevent the violent and uncontrollable engagement characteristics of paddle 

type metallic discs. This firm consistent engagement is easy to control. Some chatter is likely on engagement 

with rear gearing less than 3.73 in street applications. Each set includes the pressure plate, clutch 

disc, release bearing, and alignment tool unless otherwise 

noted. Use Powergrip HD for power levels to 650

KEY FEATURE: 

All RAM performance discs feature an 8 spring hub with 

urethane coated springs for extended center hub life. 

NOTE: Sport compact applications require the next higher 

product level due to smaller diameters.

STREET DUAL CLUTCHES 

You were told, "you can't have your cake and eat it too". THAT'S NO LONGER TRUE FOR PER- 

FORMANCE CLUTCHES. The RAM Street Dual affords perfectly smooth engagement for street 

driving yet handles horsepower levels in excess of 1000! The premise of the Street Dual is driveability 

for yesterday and today's muscle cars. Street Dual units use our 300 series steel backed friction 

discs in a sprung hub top/solid hub bottom arrangement. The sprung clutch disc features an eightspring 

hub assembly with urethane encapsulated springs for added durability, and a marcel spring 

that helps eliminate the 'on/off' switch operation of most dual disc clutches. The floater plate drives 

from six stands, three of which are composite to help reduce floater plate noise. For severe duty 

applications, 6 steel stands are recommended. 


A billet aluminum flywheel rounds out the package 

that weighs in at an average of 45 pounds.

BILLET STEEL AND 

ALUMINUM FLYWHEELS 

All billet flywheels are not created equal! Make sure you are getting the features you pay for. RAM 

billet steel and aluminum flywheels are fully machined and assembled in house. That means when 

you get your RAM billet flywheel, it is already surface ground, already balanced, and ready to install 

out of the box. A key feature of RAM aluminum flywheels is the steel insert. A flywheel insert must 

have enough mass to wick heat away from the clutch without distorting. RAM uses a .250-inch thick 

inset that is riveted in before the flywheel is surface ground. This assures a parallel friction surface 

with no run out, and enough material to adequately wick the heat while maintaining flatness over 

time that thinner inserts simply cannot do. All RAM billet flywheels are SFI certified.
