MAHLE 3150036-060 Plasma-Moly Piston Ring Set Bore - 4.060 8-Cylinder

The MAHLE 3150036-060 is a precision-ground, plasma-moly piston ring set designed for 8-cylinder engines with a 4.060-inch (0.060" oversize) bore. Engineered under strict quality controls, this set delivers OE-quality materials and performance-focused design for engine rebuilds and overhaul applications requiring a reliable, long-lasting ring seal.

MAHLE is the world's largest piston ring manufacturer, with over a century of experience supplying rings to leading OEM engine programs. The 3150036-060 carries that same engineering expertise into the aftermarket, offering a ring set that installs correctly the first time and performs reliably under demanding conditions.

Key Features:

• Plasma-moly top ring: Plasma-moly face coating provides superior scuff resistance, faster break-in, and long-term durability under high heat and pressure
• Barrel-faced top ring: Maintains consistent cylinder wall contact as the piston rocks at TDC and BDC for improved compression sealing
• Napier (Tapered Hook Groove) second ring: Acts as a check valve to relieve combustion pressure buildup beneath the top ring while providing superior oil scraping on each down stroke
• CP-20 3-piece oil control ring: Features a 20-degree ear angle and stainless steel expander between two chrome-faced steel rails for maximum conformability and oil drain-back
• Precision-ground ring faces: High-strength materials with special ring face contours and torsional designs ensure optimum compression sealing and oil control
• Foolproof installation design: Ring sets are built so they cannot be installed incorrectly, saving time and reducing the risk of assembly errors
• Ring widths: 1/16 in. top, 1/16 in. second, 3/16 in. oil
• Bore size: 4.060 in. (+0.060 in. oversize)

The MAHLE 3150036-060 plasma-moly piston ring set is the ideal choice for engine builders seeking a proven, technically advanced ring package that maximizes combustion sealing, minimizes frictional losses, and delivers consistent reliability from the first startup.
