Description

Proper ring sealing is critical for maintaining compression and controlling blow-by in high-displacement motors—weak or worn rings kill power and destroy oil integrity. The HASTINGS 107" piston ring set delivers OEM-matched geometry with engineered improvements for superior oil control and longevity, making it the right choice for rebuild and performance applications. This is a complete two-piston ring kit manufactured to exacting tolerances right here in the USA.
