Maintain optimal cylinder sealing and engine longevity with this Supertech high-performance piston ring set. Specifically engineered for engines with an 86.5mm bore, these rings are subjected to a gas nitriding process that creates a hardened, low-friction surface capable of withstanding the extreme temperatures and pressures of forced induction or high-RPM operation.
