MAHLE 3021032B Performance Piston Ring Set

The MAHLE 3021032B is a performance piston ring set engineered to deliver superior sealing, reduced friction, and long-term durability in high-demand engine applications. MAHLE has pioneered the use of piston ring simulation and computer development tools to design rings that deliver measurable horsepower gains by minimizing parasitic friction losses.

MAHLE's ultra-flat ring flanks and precision surface finish maximize ring-to-piston groove sealing, keeping combustion gases where they belong and oil where it shouldn't be. The result is improved compression retention, cleaner combustion, and reduced oil consumption across the full RPM range.

Key Features:

• Precision-engineered ring set designed to minimize friction and maximize sealing efficiency
• Barrel-faced top ring profile for rapid break-in and consistent cylinder wall contact through piston rock at TDC and BDC
• Napier taper hook groove (THG) second ring for superior oil control, combustion gas management, and top ring stability
• CP-20 oil control ring with exclusive 20-degree ear angle for optimal cylinder wall seal
• Available ring materials include cast iron, ductile iron, gas nitride stainless steel, and steel alloy construction
• Ultra-flat ring flanks and precision finish for maximum ring-to-piston sealing
• Engineered and tested to withstand high RPM, elevated compression ratios, and extreme operating temperatures

MAHLE performance piston rings are developed using the same simulation tools and engineering processes trusted by professional racing programs. Whether used in a performance street build or a dedicated competition engine, the 3021032B ring set provides the quality and precision MAHLE is known for worldwide.
