Mahle pistons are designed as a complete, drop-in forged piston assembly including a performance piston ring set. With over 80 years of manufacturing experience, these pistons feature an anti-friction skirt coating for reduced drag and are forged from 4032 low expansion aluminum alloy for high strength and reduced piston-to-wall clearance. Key features include a forced pin oiler, CNC precision-machined pin bores, a high-quality steel wrist pin, a 1.5, 1.5, 3.0mm file-fit performance ring set, and Race Proven Round Wire Locks. These pistons are engineered for Chrysler Big Block engines with specific dimensional requirements.
