The MAHLE 8600MS-12 is a high-performance piston ring set designed for 86.00mm bore applications. This set includes rings for four pistons and features MAHLE's advanced friction-reduction technology developed through proprietary piston ring simulation and computer modeling.

Key Features:

  • 86.00mm bore diameter with 1.2mm/1.2mm/2.8mm ring widths
  • Complete set includes rings for 4 pistons
  • Ultra-flat ring flanks for maximum ring-to-piston sealing efficiency

Great prices and fast shipping. Saved $100 buying here. Will do business again

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

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 cheap we will see

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