MAHLE 3010982B Performance Piston Ring Set Bore Plasma-Moly Steel - 4.130 1.5mm

The MAHLE 3010982B is a high-performance piston ring set engineered for demanding racing and performance engine applications. This set features a 4.130-inch bore diameter with a modern 1.5mm, 1.5mm, 3.0mm ring pack configuration designed to reduce friction and maximize horsepower.

Key Features:

• 4.130-inch bore diameter with .151-inch reduced radial wall thickness
• 1.5mm plasma-moly faced steel top compression ring for exceptional durability and scuff resistance
• 1.5mm second compression ring with tapered face for superior oil control
• 3.0mm oil control ring assembly for optimal oil management
• Low-tension design minimizes friction losses and frees up horsepower
• Barrel-faced ring profile ensures proper cylinder wall contact and seating
• Reduced radial wall construction allows ring grooves to be positioned higher on piston, reducing crevice volume
• SAE 9254 steel construction provides superior strength and eliminates ring breakage

MAHLE's plasma-moly face coating combines the strength of steel with excellent wear resistance and scuff protection, making this ring set ideal for high-RPM, high-cylinder-pressure applications. The thinner 1.5mm ring pack reduces mass and inertia, allowing the rings to better follow the cylinder wall and maintain sealing at high engine speeds. Each ring set is precision-manufactured to exacting tolerances for reliable performance and easy installation.
