Product Details

The MAHLE 41879CP.040 is a premium plasma-moly piston ring set engineered for precision fit and long-term engine performance. Designed as a +0.040" oversize set, these rings are ideal for engines that have been bored over standard and require correctly sized replacement rings to restore proper compression and oil control.

Key Features:

  • Pre-lapped design seats immediately upon installation, virtually eliminating traditional break-in time
  • Plasma-moly upper compression ring (UCR) with barrel-faced contact surface for efficient combustion sealing and reduced blow-by
  • CNC-controlled gap chamfer on compression rings optimizes compression retention and minimizes combustion gas leakage
  • Intermediate compression ring features a reverse twist design for superior groove side sealing, with taper-race machining to enhance cylinder wall contact
  • CP-20 oil control ring assembly with an exclusive 20-degree ear angle for optimal side sealing against the cylinder wall
  • Chemical-polished oil ring expander promotes enhanced oil drain-back for improved oil control
  • Ring materials, coatings, and tension levels are application-optimized for reduced friction and extended service life

MAHLE is a globally recognized OE-level supplier whose piston rings are engineered to meet or exceed original equipment specifications. The 41879CP.040 set delivers installer-friendly design and professional-grade construction, making it a trusted choice for engine builders performing overhaul or rebuild work.

So far my experience with autoplicity has Ben good I like that u can pay with amazon

Fantastic ! Ordered a Weather Tech Cargo Liner for my 2012 Ford Explorer. Price was $60 less here than ALL other sites on web. I was skeptical that this was going to be a counterfeit -- as the price was too good to be true. I was extremely happy to receive the genuine product as I expected in less than a week -- and for $60 less than the competitors ! GREAT VALUE and great service ! I will definitely be back !!

great

Best Prices versus even Local Parts Stores, even with the shipping costs, just hope everything fits, don't we all, lol.

absolutely Awesome! Great Prices!

I haven't received my order yet but I am satisfied at how fast the order was processed and shipped. The website was very easy to navigate and best of all the prices were hard to beat. I believe I will be visiting this site again.
