Mahle

• Forged 2618 pistons for performance applications
• Fully-machined crown
• Grafal® anti-Friction coating on skirts*
• Phosphate-coated to reduce micro-welding and pin galling**
• Pin bores finished on CNC boring equipment
• Hand deburred
• High strength, light weight German steel pins
• Race-proven round wire locks
• Low drag ring pack
• Light weight slipper skirt forgings

* MAHLE’s GRAFAL® skirt coating reduces drag, scuffing, friction and cylinder bore wear; reduces piston noise.

** Phosphate coating provides the grey appearance to the MAHLE piston. This dry lubricant coating (not to be confused with a thermal film coating) provides a lubricant film in the pin bores and ring grooves until the oiling system of the engine reaches operating pressure; particularly useful during the initial start-up or break-in of engines to protect against galling and microwelding. The piston crown is still machineable.
