MAHLE 3011242 Performance Piston Ring Set Bore Steel Plasma Moly - 3.553 1.0mm HV385

MAHLE 3011242 is a high-performance piston ring set featuring a steel top ring with the patented HV385 supersonic thermal spray process for superior bonding, increased durability, and exceptional scuff resistance. This precision-engineered ring pack is designed for 3.553-inch bore applications and features a reduced radial wall thickness of .143 inches to minimize friction and maximize power output.

Key Features:

• 1.0mm steel top ring with HV385 thermal spray coating
• 3.553-inch bore diameter with reduced .143-inch radial wall design
• Steel napier second ring for improved oil control
• CP-20 oil control ring assembly for easier installation
• Ultra-flat ring flanks engineered to minimize friction and maximize ring-to-piston sealing

MAHLE pioneered the use of piston ring simulation and computer development tools to engineer rings that provide "free" horsepower by successfully minimizing friction. These performance ring sets maximize combustion sealing and minimize frictional losses to increase horsepower and oil control. The 1.0mm, 1.0mm, 2.0mm ring pack configuration delivers reduced tension and improved conformability for maximum performance in high-output engine builds.
