Product Details

The MAHLE 4015MS-15 is a high-performance piston ring set engineered for 4.010" bore engines with a +.005" oversize tolerance. This file-fit ring set features standard tension design with 1.5mm, 1.5mm, and 3.0mm ring widths, providing optimal sealing and performance for performance and racing applications.

Key Features:

  • 4.010" bore diameter with file-fit design for precise end gap adjustment
  • Top ring: Ductile iron with plasma moly coating and barrel face profile for superior wear resistance
  • Second ring: Cast iron reverse twist design for improved oil control
  • Oil ring: 3-piece standard tension configuration
  • Ultra-flat ring flanks maximize ring-to-piston sealing efficiency
  • Advanced friction reduction technology delivers measurable horsepower gains

MAHLE has pioneered piston ring simulation and computer development tools to engineer rings that minimize friction and unlock free horsepower. The precision manufacturing ensures consistent performance on both the dyno and the track, making these rings ideal for performance builds, rebuilds, and racing applications where maximum power and reliability are critical.

I ordered an Optima battery for my truck after I did a Google search for the battery. Autoplicity was the cheapest on the Web. Even cheaper then eBay. They got me hooked. Thanks Autoplicity

Easy to use

Best prices online for a locker and pretty fast shipping too!

Awesome place to get parts from. Went looking all over the city of houston to find a certain light everyone was sold out tried online two "Huge chain name" places were also sold out. Stumbled on Autoplicity and they had just what I needed!

Really pleased with the service I had. They had the best price I could find, and they shipped quickly. Highly satisfied
