Product Description

Wiseco domestic auto and sport compact pistons are forged and machined in-house and receive a full compliment of power enhancing features. Light weight forgings, millimeter ring packs, extra-strength forgings, gas ports, skirt coatings, offset pins, and a variety of other features are available to insure each engine exceeds our customer’s expectations. Optimized skirt profiles minimize rock and provide long skirt life in stroker applications. 

Our Sport Compact pistons are made from dedicated forgings produced in-house to give you a light weight piston with superior strength and optimal design. Being the multivalve piston technology leader, the line features specially designed valve pockets, complex dome and crown shapes, the steel nitride/napier xx rings and optimized skirt profiles. The pistons come standard with our ArmorGlide® coating material for reduced friction and noise, freeing up horsepower.

All Wiseco piston sets include pistons, wrist pins, and rings.
