MAHLE 42154CP.020 Premium Piston Ring Set 0.020" Oversize for GM 6.2L LS V8

The MAHLE 42154CP.020 is a premium-quality piston ring set engineered for GM 6.2L LS V8 engines including L9H, L94, and L92 applications from 2007-2011. This 0.020" oversize ring set is designed for rebuilt engines that have been bored to accommodate the larger diameter rings.

Advanced Ring Technology:

• SAE 9254 high alloy steel base material provides superior tensile and yield strength with extended fatigue resistance
• Plasma-moly facing on compression rings for enhanced durability and reduced friction
• Pre-lapped rings seat immediately, virtually eliminating break-in time
• CNC-controlled gap chamfer optimizes compression and reduces blowby
• Barrel-faced compression rings deliver efficient sealing and compression control

CP-20 Oil Ring Technology:

• Exclusive 20-degree ear angle provides optimal side seal in piston oil ring grooves
• Chrome-plated stainless steel construction for superior oil control
• Special chemical polish on expander enhances oil drainback
• Simplified installation design

Intermediate Ring Features:

• Reverse twist design for better groove side sealing
• Taper race machining enhances cylinder wall contact
• Cast iron construction for durability

MAHLE is one of the world's largest OE piston ring manufacturers, providing the most technically advanced piston ring technology in the industry. All ring materials, coatings, and tensions are optimized for reduced friction, minimized oil consumption, and extended service life in demanding high-performance applications.
