Description
Maximum compression and minimal blowby are non-negotiable in competitive racing, and this piston ring set delivers both. The plasma moly coating reduces friction while increasing durability under extreme cylinder pressures, making it essential for high-revving, naturally aspirated, or lightly boosted engines. File-fit design ensures you dial in the exact ring gap clearance your specific build requires—no compromises.
