MAHLE 3000700 Performance Piston Ring Set Bore Plasma Moly - 3.937

The MAHLE 3000700 Performance Piston Ring Set is engineered for high-performance engine builds requiring a 3.937-inch bore diameter. This precision-manufactured ring set features MAHLE's advanced plasma moly coating technology for superior wear resistance and enhanced sealing capabilities.

Key Features:

• 3.937-inch (100.00mm) bore diameter for precise cylinder fitment
• Top ring: .0935-inch (1/16") thickness with plasma moly inlaid coating on ductile iron construction
• Plasma moly coating provides exceptional scuff resistance and durability under high-stress conditions
• Barrel-faced top ring design with positive twist for optimal sealing
• Second ring: .184-inch thickness with reverse-twist taper face design
• Ultra-flat ring flanks maximize ring-to-piston sealing and minimize blow-by
• Computer-engineered ring design reduces friction for "free" horsepower gains
• Suitable for performance street and racing applications

MAHLE's plasma moly inlaid technology bonds the molybdenum coating directly to the ring face, ensuring superior durability compared to traditional spray coatings. This ring set is designed to meet the demanding requirements of modified engines, providing reliable performance under increased cylinder pressures and elevated operating temperatures.
