Product Details

The MAHLE 3150139-040 is a premium plasma-moly piston ring set engineered for high-performance and racing applications. This ring set features a 4.040-inch bore diameter (+.040" oversize) with ring widths of 1/16", 1/16", and 3/16", utilizing standard tension specifications and durable carbon steel construction.

Advanced Ring Design Features:

  • Plasma-moly steel top ring provides superior tensile strength, hardness, and fatigue resistance
  • Proprietary plasma face coating extends ring life and eliminates ring breakage
  • Barrel-faced top ring offers instant break-in and maintains consistent cylinder wall contact
  • Napier THG (hook groove) second compression ring delivers superior oil control
  • CP-20 oil control ring with exclusive 20-degree ear angle for optimal cylinder wall sealing
  • Reduced ring mass design tolerates high inertial forces and improves sealing effectiveness

MAHLE Original performance piston rings are rigorously tested to operate reliably at higher RPM, increased compression ratios, and elevated temperatures. The smaller cross-section design allows for closer positioning to the piston top, reducing crevice volume and unburned fuel while improving conformity to cylinder bore distortion in high-output engines.

so far so good

GREAT COMPANY TO DO BUSINESS WITH AND THE BEST PRICES I HAVE FOUND.

I'm unsure how it's connected to my amazon account but that made it faster.

nice price,

glad to find this web

Shipping took a little longer than quoted

first time user and was pleased with ease of use.

Product came fast and shipped well. Price was far better than I could find elsewhere. What else could you ask for?

Very easy to use.

Nice! Just wish you had PayPal.

Although there was a mix up with the shipping on my order customer service was helpful and expedited the solution and made it worth my trouble. I will be keeping Autoplicity in mind for any other parts I might need for my Jeep.

Best the price and shipping cost. Had a question about the product, the customer service was fast and helpful in getting my question answered
