MAHLE 3150036-045 Precision-Ground Performance Piston Ring Set Bore - 4.045

The MAHLE 3150036-045 is a precision-ground performance piston ring set engineered to OEM and aftermarket standards for reliable sealing, optimal oil control, and maximum cylinder pressure retention. MAHLE is a globally trusted manufacturer of engine components, supplying OEM rings to major automotive and powersports manufacturers worldwide.

These rings are manufactured using advanced metallurgy and precision grinding processes that ensure consistent ring gap, face geometry, and tension — critical factors for long engine life and peak performance.

Key Features:

• Precision-ground profiles for consistent ring-to-bore contact and superior sealing
• High-quality materials including ductile iron, steel, or cast iron construction depending on ring position — built to withstand high combustion temperatures and pressures
• Advanced surface treatments (such as nitride or chrome facing) on top compression rings for enhanced wear resistance
• Optimized ring tension for reduced friction and improved fuel efficiency without sacrificing oil control
• OEM-equivalent or better specifications — MAHLE supplies rings directly to major engine manufacturers globally
• 4.045" bore size — the -045 designation indicates compatibility with a 4.045-inch cylinder bore diameter
• Complete ring set includes top compression ring, second compression ring, and three-piece oil control ring assembly

MAHLE piston ring sets are a preferred choice for engine rebuilders, performance shops, and OEM production lines. The 3150036-045 is designed to meet or exceed original equipment specifications, making it an ideal solution for engine rebuilds, overhauls, or performance upgrades requiring precise bore sizing.
