Description

Forged for strength, lightweight, and low drag, these Mahle Motorsports S85 pistons are a specialized application for increased performance. They use the original bore (+0.0004") but feature a higher compression ratio. Pistons include a Grafal coating on skirts to reduce friction and wear, and a phosphate coating on other surfaces. Each set includes 6 pistons, ring set, wrist pins, and circlips. Made in the USA.
