Pistons

MAHLE pistons are OE quality and have many premium OE 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.
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.

MAHLE pistons are available from a number of Warehouse Distributors located throughout North America. Please contact our customer service representative for a location nearest to you under
