Product Details

The MAHLE 42154CP.030 is a premium plasma-moly piston ring set engineered for 2008–2017 GM LS and LT engines with a 4.095-inch overbore (standard 42154CP bore of 4.065" + 0.030" oversize). As one of the world's largest OE piston ring manufacturers, MAHLE brings factory-grade form, fit, and function to every ring in this set.

Ring Specifications:

  • Top (Upper Compression) Ring: 1.5mm axial height, 0.154" radial width — plasma-moly faced for superior wear resistance
  • Second (Intermediate) Ring: 1.5mm axial height, 0.151" radial width — reverse twist design with taper face machining for enhanced groove-side sealing
  • Oil Control Ring (CP-20 Assembly): 2.5mm axial height, 0.125" radial width — exclusive 20° ear angle for optimal side seal against the cylinder wall

Key Features:

  • Pre-lapped from the factory — seats immediately upon installation, virtually eliminating traditional break-in time
  • Barrel-faced compression ring contact area — promotes more efficient compression and reduces blowby
  • CNC-controlled gap chamfer — optimizes compression ring performance and minimizes blowby
  • SAE 9254 high-alloy steel base material — delivers higher tensile and yield strength, extended fatigue resistance, and increased material hardness
  • CP-20 oil ring expander with special chemical polish — enhances oil drainback and simplifies installation
  • Optimized ring tension and coatings — calibrated to reduce friction and extend service life

MAHLE piston rings are driven by OE requirements, reducing friction and ring mass while minimizing engine oil consumption for longer service life.

Quick n easy! Istallation is a bit rough but the product is very much worth it.

Before I buy any auto part I check prices at Autoplicity. Almost always the price is significantly lower than anywhere else: Rock Auto, Summit, Jegs, etc... <br><br>Do yourself a favor and check their prices prior to your next purchase and save yourself some money.

Very easy system!! Thanks!!

Great experience with seller. Seller had the best prices that I could find on the Internet. Seller had prices that were over 50% less than a local dealer wanted. Fast shipping.<br><br><br><br><br><br>
