MAHLE Original pistons are OE quality and have many premium OE features. Pistons have to put up with extreme pressures, as their working conditions have become significantly tougher in recent years. Naturally, the demands on pistons have also risen progressively: they must be lighter, must have lower oil consumption and must be absolutely safe and reliable. MAHLE Original pistons are reliable. In many instances, MAHLE is asked to supply the pistons for an OE manufacturer's high output, premium engines. The Chrysler 2.5L Turbo, Chevrolet 5.7L LT5 (ZRI Corvette), Chevrolet 5.7L LT1 and Chevrolet 4.3L 200HP truck engines all have our pistons. MAHLE's eutectic (12% silicon) aluminum alloy is performance proven in literally millions of engines around the world including high output diesel engines and Formula One racing.

Product Features:

• COMPENSATED RING GROOVES assure proper ring loading and oil control.
• EXPANSION CONTROLLED DESIGNS for small fitting clearances. With the tighter fitting clearances comes reduced engine noise, reduced wear, reduced emissions and improved oil control in the long term.
• PIN OFFSET for reduced engine noise.
• LIGHTWEIGHT DESIGN for reduced reciprocating mass without sacrificing reliability. This reduces bearing loads, offers smoother engine running and improves engine response. Consider, for example, the MAHLE design for the Chevrolet 4.3L 200 HP truck engine. At 520 grams, the piston is 15% lighter than other pistons offered by Chevrolet for this engine.
