Product Details

The MAHLE Original 42087CP.030 is a premium engine piston ring set engineered to meet or exceed original equipment standards. Sized at +0.030" oversize, this set is purpose-built for engine rebuilds requiring a first overbore, delivering precise fitment and reliable long-term performance.

MAHLE Original piston ring sets are designed to be installer-friendly. They are pre-lapped to seat immediately, virtually eliminating break-in time, while ring materials, coatings, and tension are all optimized for reduced friction and extended engine life.

Key Features:

  • Upper Compression Ring (UCR): Ductile iron construction with plasma-moly facing and barrel-faced contact area for efficient compression sealing and reduced blowby
  • Lower Compression Ring (LCR): Cast iron with a reverse-twist intermediate ring design for superior groove side sealing and taper-faced contact for enhanced cylinder wall engagement
  • Oil Control Ring (OCR): Stainless steel with chrome facing; CP-20 oil ring assembly features an exclusive 20-degree ear angle for optimal side sealing against the cylinder wall
  • Axial Heights: UCR — 1.5mm | LCR — 1.5mm | OCR — 3.0mm
  • Ring Types: UCR: BR-18PF | LCR: THM-10 | OCR: CP-20 Shallow Groove
  • Size: +0.030" oversize
  • CNC-controlled gap chamfer on compression rings optimizes sealing and minimizes combustion blowby
  • Special chemical polish on the oil ring expander provides enhanced oil drainback
  • Engineered to reduce friction, minimize engine oil consumption, and extend service life

MAHLE is a global OE supplier trusted by major automakers, and their Original piston ring sets bring that same engineering precision to the aftermarket. The 42087CP.030 is the ideal choice for professional engine builders and serious DIY rebuilders who demand factory-level quality and durability.

I purchased an extend-a-truck on autoplicity. It was the best price on the Internet. Autoplicity beat amazon by approximately $30. I received a confirmation it shipped the following day.

Ordered on the 20th. Received on the 26th. Parts installed within half an hour of receiving them. No complaints and I'm very happy with the transaction. Would purchase from Autoplicity again.<br> Thanks!

Just placed order to my P.O. Box. So far so good.
