Product Description

The Mahle 42108CP.020 is a plasma-moly piston ring set in +.020" oversize for the Chrysler/Dodge/Jeep/Ram 5.7L HEMI V8 (Eagle engine), covering 2009-2017 applications across the Chrysler 300, Dodge Challenger, Charger, Durango, Ram 1500, Ram 2500, Ram 4000, and Jeep Commander. This oversize set is designed for cylinders that have been bored to 3.937" -- confirm your bore size before ordering. The standard bore version (3.917") is available as 42108CP.

Mahle's plasma-moly top ring uses an RF-13PF carbon steel base with a plasma-moly face coating for reduced friction and superior scuff resistance under high cylinder temperatures. The THM-17 reverse-twist intermediate ring improves groove side sealing, and the CP-20 oil ring assembly uses Mahle's exclusive 20-degree ear angle for optimal side sealing and oil drain-back. All rings are pre-lapped at the factory for immediate seating with virtually no break-in period required. Sold as one complete 8-cylinder set. Not legal for sale or use in California.
