Industrial Injection Chevrolet Duramax Forged .040 Oversize Mahle Race Pistons Set

When you're rebuilding a Chevrolet Duramax or GMC Sierra diesel engine and need to go beyond standard bore sizes, this set of Industrial Injection Forged Race Pistons is what you're looking for. You get a complete set of four Mahle pistons, each forged from high-strength aluminum and machined to a .040 inch oversize. This means they're designed to fit cylinders that have been bored out by 0.040 inches, allowing for a fresh start on worn or damaged cylinder walls, or to achieve a slightly larger displacement for improved performance.

These pistons are built for demanding applications, featuring a robust forged construction that stands up to the high cylinder pressures common in Duramax engines. Mahle, a well-known name in piston manufacturing, brings their expertise to this set, ensuring a well-built component that's ready for serious work. The .040 inch oversize specification is critical for engine builders who are re-boring their engine blocks to a larger diameter. It's important to ensure your machine shop is aware of this specific oversize when preparing your engine block for these pistons.

This set is designed to fit a wide range of Chevrolet Silverado and GMC Sierra HD trucks from 2001 through 2015. While these pistons are built for performance, please note they are not CARB approved and cannot be shipped to California. Always consult your engine builder and follow proper installation procedures when working with performance engine components like these oversize forged pistons.
