Product Details

The MAHLE 4130ML piston ring set is engineered for 4.125" bore engines with a +.005" oversize tolerance. This file-fit ring set features low tension design to minimize friction and unlock free horsepower, making it ideal for high-performance engine builds.

Ring Configuration:

  • Top ring: 1/16" ductile iron with plasma moly coating and barrel face profile for superior sealing
  • Second ring: 1/16" cast iron with reverse twist design for optimized oil control
  • Oil ring: 3/16" three-piece low tension style for reduced friction

Key Features:

  • File-fit design allows precise end gap customization for your application
  • Ultra-flat ring flanks maximize ring-to-piston sealing efficiency
  • Low tension construction reduces parasitic friction losses
  • Plasma moly top ring coating provides excellent wear resistance and scuff protection
  • Reverse twist second ring enhances cylinder wall conformability

MAHLE pioneered advanced piston ring simulation and computer development tools to engineer rings that deliver measurable performance gains. The result is proven on both the dyno and the track, with reduced friction translating directly to increased power output and improved engine efficiency.

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

Just what I've been looking for thank you

Easy ordering and the best price I could find on the internet. However, I wouldn't have found this part by looking on the Autoplicity web site! The only way it showed up was doing a google search for that specific part.

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

Very good customer service asked about a lot of different springs and parts for my Mazdaspeed 3.
