The wrist pin deck height measures 1.270 inches, compatible with OEM connecting rods of 7.440 inches in length, making installation straightforward for most stock configurations.
Manufactured in the U.S.A., this piston kit is engineered to meet high standards of quality and precision. When using earlier connecting rods with a length of 7.470 inches, expect a slight increase in compression ratio by approximately half a point, which can enhance performance but may also require careful clearance checks to prevent clearance issues. Proper installation and clearance verification are essential to ensure optimal engine operation and longevity. This high compression piston kit is an excellent choice for enthusiasts looking to boost their engine's power while maintaining reliability and durability.
Designed for easy installation and lasting performance, the S&S Cycle piston kit is an ideal upgrade for your stock big twin motor, offering improved compression and strength to support your riding needs.
