2001-2015 GM 6.6L Duramax .040" Cast Piston Kit

Mahle is one of the most respected names in piston manufacturing.This is why we at PPE have partnered with Mahle Motorsports to produce an open-bowl, low-compression racing piston designed for high-boost applications.

With a compression ratio available from 14.5 to 16.5 (stock can be 17.5:1), it means you can fully pack the cylinders with fuel and boosted air to achieve those ultra-high horsepower and torque numbers. PPE gives you plenty of options as these pistons are available either forged or cast and comes in Standard, .020" and .040" over versions. Other options include custom compression ratios and can be had with or without valve reliefs for large cams.

Kit includes rings, pistons, pin clips and wrist pins.
