Wiseco Sport Compact pistons are made from dedicated forgings produced in-house to provide a light weight piston with superior strength and optimal design. As 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 Wiseco ArmorGlide coating material for reduced friction and noise, freeing up horsepower.

These Wiseco Forged Pistons have a 10:1 compression ratio making it an ideal solution for forced induction applications looking to run specifications close to the OEM pistons.
