Product Details

The MAHLE 42089CP.030 Premium Piston Ring Set delivers OE-quality performance with advanced engineering for demanding automotive applications. Designed with a 4.085-inch (103.759mm) bore and 0.030-inch oversize specification, this complete ring set features premium-grade materials engineered for reduced friction and extended service life.

Ring Configuration and Materials:

  • Top compression ring: 1.5mm ductile iron with plasma-moly facing for superior wear resistance
  • Second compression ring: 1.5mm cast iron with reverse twist design (THM-10)
  • Oil control ring: 3.0mm stainless steel with chrome facing (CP-20 shallow groove design)

Advanced Engineering Features:

  • Pre-lapped rings seat immediately, virtually eliminating break-in time
  • Barrel-faced compression rings provide more efficient sealing and reduced blow-by
  • CNC-controlled gap chamfer optimizes compression and minimizes combustion leakage
  • Reverse twist intermediate ring design enhances groove side sealing with taper race machining
  • CP-20 oil ring features exclusive 20-degree ear angle for superior cylinder wall sealing
  • Chemically polished oil ring expander for enhanced oil drain-back performance

MAHLE's premium piston rings are engineered with optimized ring tension and advanced coatings to reduce friction losses while maximizing durability. The installer-friendly design and precision manufacturing make these rings the preferred choice for professional engine builders and performance enthusiasts.

Excellent service. Fast shipping and email confirmation.

best price I could find...just ordered the product. Hope everything else is as good.

Ordered some headlight/taillight covers for my challenger, order # 10491. The covers were a brand that I like and for a cheap price for the pair! Can't beat that! I definetly recommend them for auto accessories, I know I'll be coming back :-)

I couldn't use PayPal but the order went smooth.

Quick and Easy so far.
