Product Details

The MAHLE 41137CP-030 is a complete moly piston ring set designed for 8-cylinder engines with a 3.766-inch bore diameter. MAHLE is a globally recognized OEM-grade supplier of engine components, and this ring set is engineered to meet or exceed original equipment specifications for reliable sealing, oil control, and long service life.

Ring Dimensions:

  • Top Compression Ring: 5/64 in. thickness
  • Second Compression Ring: 5/64 in. thickness
  • Oil Control Ring: 3/16 in. thickness

Key Features:

  • Moly-faced top ring for reduced friction and improved wear resistance during break-in and throughout engine life
  • 3.766 in. bore size — verify bore diameter before ordering; this set corresponds to a .030 in. over-bore (030 oversize)
  • Engineered for 8-cylinder applications — set includes rings for all cylinders
  • Precision manufactured to tight tolerances for proper ring-to-groove fit and consistent sealing performance
  • Helps restore compression and reduce oil consumption in rebuilt or freshened engines

MAHLE piston rings are a trusted choice for engine builders seeking OEM-quality components. The 41137CP-030 set is well-suited for engine rebuilds where the block has been bored 0.030 inches over standard, ensuring optimal fit and performance in the finished assembly.

Purchased a roll-n-lock bed cover. Ordering was easy and it was the lowest price by far that I could find online. Shipped within 48 hrs as informed. I have not yet rec'd it so I cannot comment on the packaging just yet. Sofar a good online purchase experience.

great experience, great prices. Although, it would be nice to have a description listed of the part numbers i ordered.

I was in the market for a cargo cover for my new Prius and I searched on line Autoplicity had the best price of all and plus the service was excellent as was the speed in which they promised delivery. While I have not received my shipment as of yet, I'm sure that it will be here as promised if their service is anything like what I have received already.
