Product Details

The MAHLE 4080MS piston ring set is designed for engines with a 4.080" bore diameter and features a drop-in installation with standard tension configuration. This ring set uses the 1/16", 1/16", 3/16" sizing format for precise sealing and optimal performance.

Ring Configuration:

  • Top Ring: Ductile iron construction with plasma moly coating and barrel face profile for superior wear resistance and sealing
  • Second Ring: Cast iron reverse twist design to enhance oil control and combustion sealing
  • Oil Ring: 3-piece standard tension style for effective oil management

Advanced Engineering:

  • Ultra-flat ring flanks maximize ring-to-piston groove sealing
  • Computer-optimized design minimizes friction for measurable horsepower gains
  • Plasma moly coating on top ring provides exceptional durability under high-temperature conditions
  • Reverse twist second ring improves cylinder wall conformity

MAHLE pioneered the use of piston ring simulation and computer development tools to create rings that reduce parasitic friction losses while maintaining excellent sealing characteristics. This engineering approach delivers real-world performance improvements measurable on the dyno and proven on the track.

Out of all the websites I've used to find my item, this was the lowest cost, and I'm so happy that I found them! Keep up the great work guys!

Ordered on a Thursday evening and received my parts on Tuesday. Very quick but the website couldn't provide proper tracking info.

Had the product I wanted and at the lowest price. Thank you for the outstanding service!<br><br>-M

Great price and really fast shipping. Great communication as well.

This company offers profesional service at a very competitive price. The header collectors i ordered were not available at the big speed outlets. The fast shipping was also a plus. I would recomend Autoplicity to anyone who needs parts in a hurry !

They have great prices! The same item I purchased from autoplicity is on summit racing for triple the price! This is my first order and I am very happy, will order from again!

Love that item was the cheapest found anywhere and that I could use Amazon checkout!

I was very pleased with the way my order was handled. I will definitely use them again.
