MAHLE 3150028-060 Performance Piston Ring Set Over - 0.060

The MAHLE 3150028-060 is a precision-ground performance piston ring set sized at +0.060" oversize, engineered for high-output and competition engines demanding superior sealing, reduced friction, and long-term durability. As part of MAHLE's renowned performance ring lineup, this set is manufactured to exacting tolerances using advanced materials and surface treatments that go well beyond standard OEM replacement rings.

MAHLE's performance rings are developed through piston ring simulation software and computer-aided engineering tools, resulting in a ring package designed to minimize friction losses and deliver measurable power gains. The precise ground faces and advanced coating technologies ensure rapid break-in and consistent cylinder wall contact throughout the ring's service life.

Key Features:

• +0.060" Oversize — designed for bores that have been bored or honed 0.060" over standard diameter
• Barrel-faced top ring — promotes instant break-in and maintains consistent cylinder wall contact as the piston rocks at TDC and BDC
• Napier THG (hook groove) second ring — scrapes oil from cylinder walls and creates a reservoir on each down stroke for superior oil control
• CP-20 oil control ring — features an exclusive 20-degree ear angle for optimal cylinder wall seal and oil management
• Available ring materials include cast iron, ductile iron, gas-nitrided stainless steel, and steel alloy options within the MAHLE performance series
• Precision ground to tight tolerances for consistent end gap and groove fit
• Engineered to withstand higher RPM, elevated compression ratios, and increased operating temperatures

The MAHLE 3150028-060 is the correct ring set for engines requiring a +0.060" overbore application. Whether rebuilding a street performance engine or a competition powerplant, this ring set delivers the sealing efficiency and durability that MAHLE's motorsport heritage demands.
