Product Details

The Alumiseal coating on these JE Pistons ring sets is a notable design choice, offering a unique surface treatment that helps with initial break-in and reduces friction. This specific set is designed for a 3.307-inch bore, with ring thicknesses of 1.0mm for the top ring, 1.2mm for the second ring, and 2.8mm for the oil ring. Proper ring seal is critical for engine performance, ensuring that combustion pressure stays where it belongs and oil stays out of the combustion chamber.

JE Pistons is a well-known name in performance engine building, and these rings are built to match that reputation. The Alumiseal coating is applied to help the rings seat quickly against the cylinder wall, which is especially important when you're rebuilding an engine. This means you can get back to running your vehicle sooner and with more confidence in the seal. The precise sizing ensures a snug fit within the piston groove and cylinder bore, contributing to efficient compression and oil control.

When installing these rings, always refer to the manufacturer's instructions to ensure proper gap setting and orientation. A well-sealed engine means better power delivery and improved longevity for your build.
