Product Details

The MAHLE 3150139.065 is a high-performance plasma-moly piston ring set designed for 4.065" bore engines with +.065" oversize. This precision-engineered ring set features advanced materials and coatings optimized for high-output engines that demand superior sealing and durability.

Key Features:

  • Plasma-moly steel top compression ring provides ultimate tensile strength, hardness, and fatigue resistance
  • SAE 9254 steel construction with proprietary plasma face coating extends ring life and eliminates ring breakage
  • Barrel-faced top ring design offers instant break-in and maintains 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 seal
  • Standard tension design suitable for performance and racing applications
  • Reduced radial wall thickness allows better conformity to cylinder bore distortion
  • Lower ring mass improves sealing at high RPM by reducing inertial forces

MAHLE Original performance piston rings are engineered to handle higher RPM, increased compression ratios, and extreme temperatures while maintaining reliable sealing. The precision-ground components are designed for immediate seating with minimal break-in time, making them ideal for engine builders and performance enthusiasts.

ty

so far so good

Quick and easy

Good so far, so long as it is actually in stock.

Get a 4 star for the ordering process. Not enough product information on the site but when I called they were very friendly and informative.

Tried to use Amazon for checkout and was not able to. Was able to log in but when it came back to your page it would not allow me select anything else. Used Paypal and it worked.

Great prices if it shows up in a reasonable amount of time

OK. Hope to receive my order by the specified date.
