JE Pistons Ring Sets 1.5-1.5-4mm-3.347

If you're rebuilding the top end of your 4-cylinder engine, getting the piston rings right is crucial for sealing combustion pressure and maximizing horsepower. These JE Pistons ring sets are designed for that exact purpose, offering a precise seal that helps your engine perform at its best. They come in a variety of sizes and thicknesses to fit many different engines, and this particular set is a file-fit style, meaning you can fine-tune the end gap for your specific application.

This set features a 0.0591-inch ductile iron Plasmy Moly top ring, known for its durability and ability to seal combustion pressure effectively. The second ring is also 0.0591-inch iron phosphate, providing a solid secondary seal. For the oil ring, you get a 0.1575-inch carbon steel chrome standard tension ring, which is built to manage oil and prevent it from entering the combustion chamber. These are the same types of rings used by professional racing teams, offering improved durability and reduced friction for more power.
