Mahle 4.6 / 5.4 Forged FLAT TOP Pistons w/ Rings

• ULTRA FLAT RING GROOVES, THE KEY TO POWER

Every MAHLE Motorsport piston is machined to exacting tolerances with focused attention given to the radial flatness of the ring grooves. A flat ring groove is essential in achieving and maintaining the best seal possible. The quality of the ring grooves is so critical to peak and lasting performance, that MAHLE designed and built the machinery used to machine the ring grooves for its MotorSport piston assemblies. Combined with ultra flat MAHLE rings that are included in every PowerPak piston kit, MAHLE delivers the formula for the best sealing power cell on the market.

• A TRUE PERFORMANCE COATING

MAHLE Motorsports’ proprietary Grafal® anti-friction skirt coating is like no other on the market. It is graphite impregnated to reduce drag like many other skirt coatings, but this is where the similarities end. The screen print application provides superior adhesion and is designed to last 100,000+ miles. Because Grafal® is a compressible membrane with a unique cushioning property, harsh contact between the piston skirt and the bore is dramatically reduced. Resulting in much less wear on the bore and significantly reduces piston skirt fatigue.

• LOOKS CAN BE DECEIVING, NOT ALL FORGINGS ARE ALIKE

MAHLE Motorsport, creators of the “Slipper Skirt” forging design, uses strong, lightweight, low drag forgings in every PowerPak piston kit. Not all piston manufacturers can make that claim. A Slipper Skirt forging offers many benefits over the standard “Full Round” design, but the technology runs much deeper than looks alone. These benefits are only achieved through the proper management of the design; any misapplication can result in a similar looking part with poor performance.
