Mahle 42108CP.010 Engine Piston Ring Set

Overview

MAHLE 42108CP.010 is a premium piston ring set for engines that require a 0.010 in oversize and a shallow groove configuration. It uses a plasma-moly faced top ring, carbon steel top ring construction, and stainless steel oil ring assembly materials to support controlled sealing and reduced oil consumption.

Compatible with Chrysler, Dodge, Jeep, and Ram applications, this set is built for specific engine rebuild needs rather than general use. The MAHLE 42108CP.010 part number is also referenced by installers looking for the same application as Hastings 2M5141.010.

The MAHLE 42108CP.010 part number should be matched to the engine’s bore and ring groove requirements before assembly.

What It Is Used For

• Restoring cylinder sealing during an engine rebuild
• Reducing oil consumption caused by worn rings
• Addressing compression loss from ring wear
• Replacing rings in engines that require a 0.010 in oversize

Installation Notes and Tips

Verify bore diameter, ring groove dimensions, and oversize requirements before installation. Confirm the piston ring set matches the engine’s specified bore of 3.9272 in and the shallow groove design. Clean the ring lands thoroughly and follow the engine builder’s ring end-gap and break-in procedures during assembly.
