• New skirt coatings use Wiseco's 

proprietary ArmorGlide material. 

Benefits include - longer engine 

life, increased HP, noise reduction, 

and much tighter dimensional 

tolerances than typical spray-on 

coatings. Controlled curing 

processes guarantee the best 

possible results.

Wiseco Quick 16 pistons are designed to fit conventional heads from today's leading manufacturers. 

Wiseco Quick 8 pistons are designed to allow for additional flycutting as necessary. Domes that can be cut to a 

lower rise to tune volume for different combustion chamber volumes. Every 2.76 grams off dome/valve pockets = 1cc 

volume. 

• New skirt coatings use Wiseco’s proprietary ArmorGlide material (Superior to graphite or Teflon based formulas). 

Benefits include - longer engine life, increased horsepower, noise reduction, and much tighter dimensional 

tolerances than typical spray-on coatings. Controlled curing processes guarantee the best possible results. 

• Designed with input from today's leading edge engine builders and Pro Stock technology to fill the demands of 

today's big valve, big cubic inch Sportsman Series engines. 

• Vertical Gas Ports located away from valve pockets. 

• Oil reservoir below oil drainbacks allow the lower rail to act more efficiently for optimal oil control. 

• In stock availability of kits and singles keeps you racing all season.
