MAHLE 3030843B Performance Piston Ring Set Bore Low Tension - 4.185 1.0mm 1.0mm 2.0mm Chrome

The MAHLE 3030843B is a high-performance piston ring set engineered for 4.185-inch bore applications, featuring a low-drag 1.0mm, 1.0mm, 2.0mm configuration designed to minimize friction while maximizing power output. This ring set represents MAHLE's advanced ring simulation and computer development technology, delivering measurable horsepower gains on the dyno and track.

Key Features:

• 4.185-inch bore diameter with .113-inch (2.0mm) radial width oil ring assembly
• 1.0mm steel top compression ring with HV385 thermal spray coating for superior bonding and scuff resistance
• 1.0mm steel second ring with phosphate coating for optimal sealing and oil control
• 2.0mm low-tension chrome-plated stainless steel three-piece oil ring assembly
• File-fit design allows precise end gap adjustment for optimized sealing
• Reduced friction design provides "free" horsepower by minimizing parasitic losses
• Chrome oil ring segments deliver superior durability and cylinder wall protection

MAHLE's patented HV385 supersonic thermal spray process creates a ring face coating with exceptional strength and scuff resistance, ideal for high-performance and racing applications. The low-tension oil ring assembly maintains effective oil control while reducing drag on the crankshaft. This coordinated ring set is precision-engineered to exceed demanding performance requirements in modified and racing engines.
