JE Pistons Ring Sets 100.5mm Bore 1.0mm Top Ring 1.2mm Second Ring 2.8mm Oil Ring

When you're rebuilding an engine, the piston rings are a critical piece of the puzzle for getting good compression and keeping oil where it belongs. This set from JE Pistons is built for a 100.5mm bore, featuring a file-fit design so you can achieve a perfect seal in your cylinders. They're made with a carbon steel nitride top ring and oil ring, known for their durability and sealing ability, paired with a ductile iron phosphate second ring.

JE Pistons is a well-known name in performance engine building, and these rings are made with the same attention to detail that goes into their top-tier racing components. The file-fit nature means you'll need to gap them yourself to match your specific engine build, which is standard practice for performance applications where precise control over ring tension and sealing is key. This set includes the necessary rings for a 4-cylinder engine.
