    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.
    • 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

    Performance Forged - Forged diesel pistons are best suited for dedicated drag and pulling vehicles. Although the Performance Forged pistons are stronger, the lack of a steel top ring groove in the forging will result in a limited lifecycle for street applications. Strength and design flexibility still make the Performance Forged piston a favorite for competition only applications.
    • CNC machined from MAHLE's exclusive M142S alloy chosen for its good high temperature strength and low expansion characteristics.
    • Performance bowls with design features intended to reduce erosion issues caused by high pressure, long duration, advanced injection timing.
    • Customer specified Compression Ratios
    • Fully radiused valve pockets where applicable to reduce stress and fatigue cracking
    • Hard anodized top ring groove for add durability and increased longevity
    • Grafal® coated skirts for reduced drag and increased scuff resistance

    Extreme duty MONOTHERM® - Providing unmatched strength and durability, the MONOTHERM® piston will enable you to step to the next level or tow longer with confidence.
