Engine Piston Ring Set Overview

Mahle piston ring set 41510CP.030 is a premium oversize ring set for 4.030-inch bores. It is built around low-friction ring technology and OE-driven engineering for engines that need controlled oil use and durable sealing.

Key Features

  • 0.030-inch oversize for 4.030-inch bore applications
  • Plasma-moly face coating for improved wear resistance
  • Carbon steel top ring, cast iron second ring, and stainless steel oil ring assembly
  • Shallow groove design for matched ring package fitment
  • Premium-grade construction for rebuild applications

Detailed Description

Mahle 41510CP.030 piston rings are engineered for rebuilds that require precise bore sizing and consistent ring control. The ring package combines a carbon steel top ring, cast iron second ring, and stainless steel oil ring assembly, with a plasma-moly face coating to reduce friction and support long service life. This set is suited to engines using a shallow groove configuration and a 0.030-inch oversize bore specification. Compatible With American Motors Concord, Eagle, and Spirit applications, as well as Buick Skylark, Chevrolet Citation, Jeep CJ5, Jeep CJ7, Jeep Scrambler, Oldsmobile Omega, and Pontiac Phoenix applications listed in the fitment data. Part number 41510CP.030 is also referenced by Hastings 2M5630030 and Sealed Power E383K30 for the same application.

What It Is Used For

  • Restoring cylinder sealing after wear or scoring
  • Reducing oil consumption caused by worn ring packs
  • Improving compression retention in rebuild work
  • Replacing rings in engines that require 0.030-inch oversize sizing

Installation Notes and Tips

Verify bore diameter, ring groove style, and oversize requirement before installation. Confirm the engine matches the listed shallow groove configuration and inspect cylinder walls for taper or damage before assembly. Follow the engine builder’s ring end-gap and break-in procedures for the specific application.

Quality Assurance

Mahle develops piston rings to OE requirements, with an emphasis on reduced friction, lower ring mass, controlled oil use, and extended service life. Part number 41510CP.030 reflects that engineering approach for rebuild-focused applications.
