MAHLE Motorsports Performance Cast Pistons Kit ,.040 16.6CR w/.075 Pockets (Delipped with Machine Valve Reliefs) 2001-2016*

The Mahle Diesel PowerPak is a complete race-proven piston assembly kit composed of hand deburred, forged, performance coated pistons, high-quality steel pins, round wire locks and low drag performance rings.
It may seem crazy, but you really can get 8, 14, or even 22 more HP with Mahle pistons and rings. The secret is in Mahle's ultra flat ring grooves and low drag rings. Improved sealing minimizes parasitic drag to create ''free'' horsepower.


Performance coatings include a phosphate dry lubricant (not to be confused with a thermal film coating) that is used to protect against ring micro-welding and pin galling during initial startup and break-in. For additional performance, Mahle applies its proprietary Grafal anti-friction coating to each piston skirt.


Performance Cast - Designed for street/strip or pulling trucks making 400-1000Hp that still get used as a daily driver or work truck. Machined from OE castings (retaining the steel top ring insert) giving the same drivability and longevity of an OE piston with additional strength through industry leading design technology. •Performance bowls with design features intended to reduce erosion issues caused by high pressure, long duration, advanced injection timing.

*Pistons Delipped with Machine Valve Reliefs
•Lower compression ratio (.5 to 1.5 points) allowing more flexibility for high output tuning.
•Fully radiused valve pockets where applicable to reduce stress and fatigue cracking.
•MAHLE's proprietary Grafal® skirt coating for reduced drag and increased scuff resistance.
•Rings, pins and clips included
