Piston Ring Set 4.505 Bore 1.5 1.5 3.0mm

The Piston Ring Set 4.505 Bore 1.5 1.5 3.0mm by MAHLE PISTONS is a precision engine component designed for high-performance and stroker engine builds that require custom bore sizing. This four-piece ring set is specifically engineered for 4.505-inch bore applications, making it an excellent choice for serious engine rebuilds and performance modifications.

MAHLE's engineering features two compression rings at 1.5mm thickness each, along with a 3.0mm oil control ring. This configuration effectively balances sealing integrity with minimal friction losses, ensuring optimal performance. The 1.5mm compression rings help reduce piston skirt stress while maintaining critical gas sealing in the combustion chamber, while the 3.0mm oil ring excels at controlling oil flow.

Engine builders working with custom pistons or performance applications will find this ring set essential for maintaining engine longevity and efficiency. Its premium materials and tight manufacturing tolerances ensure consistent performance, making it suitable for engines running elevated boost or extended RPM ranges.
