Product Details

The MAHLE 4000MS-112D is a performance drop-in piston ring set designed for a 4.000-inch bore diameter with a 1.0mm / 1.0mm / 2.0mm ring pack configuration. Engineered by MAHLE Motorsports, these rings are built to deliver reliable sealing performance, reduced friction, and durability in high-performance and race engine applications.

MAHLE's drop-in ring sets are manufactured to strict tolerances and are designed to work with a wide range of pistons, making them a popular choice for engine builders performing rebuilds or upgrades. The narrow 1.0mm top and second rings reduce reciprocating mass and friction, while the 2.0mm oil control ring provides effective oil management.

Key Features:

  • Bore Size: 4.000 inches
  • Ring Pack: 1.0mm Top / 1.0mm Second / 2.0mm Oil
  • Drop-in design compatible with a wide range of pistons
  • Moly-faced top ring for enhanced wear resistance and sealing
  • Manufactured to strict dimensional tolerances for consistent gap and fit
  • Suitable for high-performance street, track, and racing engine builds
  • MAHLE Motorsports quality engineering and materials

Whether you are building a fresh engine or replacing worn rings, the MAHLE 4000MS-112D offers professional-grade performance in a convenient drop-in format. Part number cross-reference: 4000MS-112D.

Everything was quick, simple and straightforward. I liked having a picture of the item I was looking for. I entered my specific vehicle as well to check compatibility. Price was much lower than everyone else. And I was able to pay with Paypal, which I feel is much more secure for online shopping. I received the item quickly, delivered to my door. The lugs have already been installed on the vehicle and were exactly as ordered. I would use this company again.

Quick, easy and the best price
