Victor 42101CP Engine Piston Ring Set Shallow Groove 3.464" Bore

The Victor 42101CP is a premium-grade engine piston ring set designed for shallow groove applications. This complete set features a 3.464-inch (87.986mm) bore diameter and includes rings for a 4-cylinder engine with precision-engineered ring thicknesses of 1.2mm, 1.5mm, and 2.5mm.

Construction and Materials:

• Upper compression ring: Carbon steel with chrome facing for durability and heat resistance
• Lower compression ring: Cast iron with chrome facing for optimal sealing
• Oil control ring: Stainless steel CP-20 assembly with chrome facing
• Pre-lapped design for immediate seating and virtually eliminates break-in time
• CNC-controlled gap chamfer to optimize compression and reduce blow-by

Engineering Features:

• Barrel-faced compression ring contact area for more efficient compression
• Reverse twist design on intermediate rings for better groove side sealing
• 20-degree ear angle on oil ring assembly for superior side seal
• Ring materials and coatings optimized for reduced friction and extended life
• Taper race machining to enhance contact and performance

This standard-size ring set is sold as a complete set for one cylinder and represents MAHLE's commitment to quality engineering for modern high-performance engines running at elevated temperatures and cylinder pressures.
