SBC250155F05 - Mahle PowerPak Piston Kits

Representative Image
Product images may differ from actual product appearance.

The Mahle 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 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.

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 oil system of the engine reached operating pressure; particularly useful during the initial start-up or break-in of engines to protect against galling and micro welding. Piston crown remains machine able.

Mahle's Grafal Skirt Coating - Reduces drag, scuffing, friction and cylinder bore wear; reduces piston noise.
