MAHLE 42106CP.010 Moly Piston Ring Set GM 2.8L V6 LP1 +0.010 Oversize

The MAHLE 42106CP.010 is a moly piston ring set engineered for the GM 2.8L V6 LP1 engine. Designed to OE standards, this +0.010" oversize ring set delivers superior sealing performance, reduced friction, and extended service life — making it an ideal choice for engine rebuilds and overhauls requiring a slightly oversized bore.

MAHLE Original piston rings are built to meet or exceed original equipment requirements, with ring materials, coatings, and tension levels carefully optimized for each specific application. The set is pre-lapped at the factory for immediate seating, virtually eliminating traditional break-in time and simplifying installation.

Key Features:

• Moly ring coating for reduced friction and enhanced wear resistance
• +0.010" oversize bore specification for engines that have been bored or honed to oversize
• Pre-lapped design seats immediately, reducing break-in time
• Barrel-faced compression rings with CNC-controlled gap chamfer to optimize compression and minimize blow-by
• Reverse twist intermediate rings for superior groove side sealing and taper race machining for enhanced contact
• CP-20 oil ring assemblies with exclusive 20-degree ear angle for maximum cylinder wall side sealing
• Special chemical polish on the oil ring expander promotes enhanced oil drain-back
• Engineered to OE requirements for reduced ring mass and minimized engine oil consumption

The MAHLE 42106CP.010 piston ring set is sold as a complete set and is compatible with the GM LP1 2.8L V6 engine platform. Note: This product is NOT CARB-approved and is not legal for sale or use in California.
