Mahle PowerPak Piston and Ring Kit for 408ci/418ci Small Block Ford, 4032 Alloy (Set of 8)

The POWERPAK kit is the racer’s best value. Developed for high-performance enthusiasts and engine builders who want uncompromising reliability, the POWERPAK delivers just that.

These forged piston kits are made from 4032 aluminum alloy, which allows for tighter cylinder-to-wall clearances and improved temperature stability. In addition to fully machined crowns and CNC machined pin bores, the pistons are dual coated with phosphate to reduce micro-welding and pin galling, and the skirt features a GRAFAL® anti-friction coating. Each set includes low-drag rings proven to increase horsepower and torque, clips and application-specific pins—all designed to ensure minimum friction and maximum horsepower.
