Product Details

The MAHLE 41870CP.040 is a premium plasma-moly piston ring set engineered to OE form, fit, and function standards. Designed for six-cylinder engines, this 0.040-inch oversize set features a 3.915-inch (99.441mm) bore diameter with 1.5mm / 1.5mm / 4.0mm ring thicknesses (top / second / oil).

Key Features:

  • Plasma-Moly Top Ring: Cast iron upper compression ring with a plasma-moly facing and barrel-faced contact area for more efficient compression and reduced blow-by, with a CNC-controlled gap chamfer for precise fitment
  • Pre-Lapped Design: Rings are pre-lapped at the factory to seat immediately, virtually eliminating engine break-in time
  • SAE 9254 High-Alloy Steel Construction: Provides higher tensile and yield strength, extended fatigue resistance, and increased material hardness for long service life
  • Intermediate (Second) Ring: Features a reverse twist design for better groove side sealing and taper race machining to enhance cylinder wall contact and oil control
  • CP-20 Oil Ring Assembly: Exclusive 20-degree ear angle provides the best possible side seal against the cylinder wall; chemical polish on the oil ring expander offers enhanced oil drain-back performance
  • Optimized Ring Tension: Ring tension is precisely tuned to minimize friction while maximizing sealing efficiency and engine longevity

Easy to use website

First off, the price was excellent and they communicate every step of the sale. Shipping was immediate and arrived promptly with the complete order. One observation is the shipping calculator is flaky. I had to revise the order during checkout and noticed it seemed to give a different price each time. 6 cans of satin black $12 add 6 more of gloss, $15 change to 12 of the satin then $24 cancel order and purchase 12 satin then back to $15

Had exactly what I wanted. Shopping cart did not have an update button for new quantity

Ordered a CTEK charger. Great price, and recieved it in 3 days. Very pleased.

Very easy system. I hope the shipping is fast too.
