Notes
- Forged piston for performance applications
- Fully-machined crown
- Grafal anti-Friction coating on skirts
- Phosphate-coated to reduce micro-welding and pin galling
- Pin bores binished on CNC boring equipment
- Deburred
- High strength, light weight steel pins
- Race proven round wire locks
- Low drag ring pak
- Lightweight slipper kirt 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.
