CP Piston Turbo Ring Set 1.2mm Top Ring 1.2mm 2nd Ring 2.0mm Oil Ring 87mm bore PVD

If you're building a performance engine that's going to see boost, getting the right piston rings is crucial for sealing and longevity. This turbo ring set from CP Pistons is designed for an 87mm bore, featuring a specific ring package that works well under pressure.

This set includes a 1.2mm top ring, a 1.2mm second ring, and a 2.0mm oil ring. The PVD (Physical Vapor Deposition) coating on these rings is a notable upgrade over standard moly or cast iron rings. It creates a harder, smoother surface that reduces friction and wear, which is especially important in high-performance, turbocharged applications where heat and stress are significantly higher. This improved surface helps maintain a good seal between the piston and cylinder wall, contributing to better power delivery and engine health.
