JE Pistons Ring Sets 1.2-1.2-2.0-82.00 PVD

The 1.2mm top ring on this JE Pistons set features a PVD coating, a tough surface treatment that helps it stand up to wear and tear. This is important because the piston rings are what seal the combustion chamber, keeping pressure where it belongs and preventing oil from getting into the cylinder. When you're rebuilding an engine, getting the ring seal right is key to performance and longevity.

These rings are designed for an 82.00mm bore size, which is a common measurement for many engines. The specific ring dimensions are 1.2mm for the top ring, 1.2mm for the second ring, and 2.0mm for the oil control ring. This combination is chosen to balance sealing, oil control, and ring tension for optimal engine operation. JE Pistons is a well-known name in performance engine building, and their rings are a solid option when you need reliable components for your rebuild.
