Product Details

The MAHLE 4155MS-15D is a high-performance piston ring set designed for 4.155-inch bore applications. This drop-in style ring set features metric ring widths of 1.5mm, 1.5mm, and 3.0mm, offering an alternative to traditional fractional measurements for modern engine builds.

Key Features:

  • Bore size: 4.155 inches with drop-in fitment for easy installation
  • Ring widths: 1.5mm top ring, 1.5mm second ring, 3.0mm oil ring
  • Top ring: Plasma moly-coated ductile iron with barrel face profile for superior wear resistance
  • Second ring: Reverse twist design with tapered face in cast iron construction
  • Ultra-flat ring flanks maximize ring-to-piston sealing
  • Standard tension design balances sealing performance with reduced friction
  • Complete 8-cylinder set included

MAHLE pioneered piston ring simulation and computer-aided design to create rings that minimize friction while maximizing sealing performance. Backed by over 90 years of racing heritage, MAHLE Performance piston rings deliver proven reliability for street performance and racing applications.

Good price and very fast shipping.

I had been searching many sites for a better price on shocks for my 1999 Ford Explorer, upon finding Autoplicity the savings was 13.00 cheaper than all others. I instantly made the purchase. wish i had knew about them before I purchased the other items for my truck. will return as a customer .

By far they had the cheapest prices. I made a mistake on my order and they were able to switch it out for the correct item before it shipped. Amazing guest service over the phone, will def shop again with their low prices.
