Mahle Motorsport has introduced an all-new 5.3L LS PowerPak Plus piston assembly, which it states has been designed with serious racers in mind.
Mahle also states that the new piston design features attention to detail and precision machining ‘where it matters most’. Designed with 2618 alloy slipper skirt forgings to minimize weight while adding strength to key areas, the pistons feature lateral gas ports to promote optimal ring seal and power. A triple surface treatment is then applied beginning with a phosphate dry film, followed by hard anodized top ring grooves to protect against microwelding, and Mahle’s proprietary Grafal skirt coating to reduce drag and wear.
Topping off this comprehensive combination is Mahle’s revolutionary HV385 1.0mm, 1.0mm, 2.0mm all steel ring package and a heavy duty .188” wall wrist pin for the strength to withstand the toughest race application conditions.
