Product Details

The MAHLE 51869CP is a precision-ground performance piston ring set engineered to OE-quality standards, delivering reliable compression sealing, superior oil control, and trouble-free installation for engine rebuilds and re-ring jobs. MAHLE is the world's largest piston ring manufacturer, with over a century of experience supplying rings to OE engine manufacturers and the professional aftermarket alike.

Key Features:

  • Precision-ground construction — rings are pre-lapped to seat immediately, virtually eliminating break-in time
  • Barrel-faced top compression rings — CNC-controlled gap chamfer optimizes compression and reduces blow-by
  • Reverse-twist intermediate rings — taper-race machining and reverse twist design provide better groove side sealing and enhanced cylinder wall contact
  • CP-20 oil ring assembly — exclusive 20-degree ear angle delivers superior side sealing against the cylinder wall; chemically polished expander promotes enhanced oil drain-back
  • 3-piece oil ring design — stainless steel expander between two chrome-faced steel rails provides a high degree of conformability within the cylinder bore
  • Optimized ring tension and coatings — materials and surface treatments are matched to each application for reduced friction and extended service life
  • Foolproof installation design — rings are engineered so they cannot be installed incorrectly, saving time and preventing costly errors
  • High-strength materials — special ring face contours and torsional designs ensure optimum compression sealing and oil control under demanding conditions

Whether you are performing a complete engine overhaul or a simple re-ring, the MAHLE 51869CP piston ring set delivers the OE-grade quality, performance consistency, and installer-friendly design that professional engine builders depend on.

Great prices very fast shipping!!!

very good so far. waiting to see how delivery goes. thanks

Very easy to find the parts I needed and great price half the cost of my local parts store

1st time shopper order shipped quickly very satisfied

I was unable to check out with Paypal

I would definetly order from Autoplicity again. Fast curtious service they had just what I wanted and the prices were the best I could find.

Great price. Minor problems with shipping because of UPS (dropped box and broke part, late delivery). Autoplicity sending me out replacement part.

Hi - I just want to say what a great job your customer service person - Rob Fratu did for me. I purchased a set of Mickey Thompson Indy tires thru Autoplicity's internet site. To my misfortune; the tires were out-of date (manuf. in 2005)when they were shipped from the warehouse. One of the tires immediately began to split around the outerside wall once it was mounted. I emailed pictures to Rob ; and he took care of the entire situation and got 100% of my purchase refunded to me.<br>I want to thank Rob for all his assistance and for Autoplicity for taking care of the customer and standing behind their business!! I must admit - I was a little worried and expected the worst? thanks again - best regards - Willis Hiscock
