LS7 Mahle Forged Flat Top & Inverted Pistons and File Fit Performance Ring Set (4.185 in. Bore for 6.125 in. Rods, -6cc)


Model Number: 930221985

Mahle’s PowerPak piston assemblies include forged pistons, piston rings, pins, and wire locks–all in one race-proven package. The pistons are hand-deburred and then coated with dry phosphate to protect against ring micro-welding and pin galling during initial startup. For additional performance, Mahle added its proprietary Grafal anti-friction coating to the piston skirts. Low drag rings, steel pins, and round wire locks complete the Mahle PowerPak package
