About this part

Product Details

When you're rebuilding a worn-out engine, replacing internal components is key to getting back that original performance. This Omix piston ring set is designed to fit a wide range of Jeep models from 1972 through 1990, including the CJ5, CJ7, Scrambler, and Wrangler YJ, as well as various Cherokee, Wagoneer, and J-Series trucks. These rings are specifically sized at 0.060 inches over the standard bore, which is crucial for engines that have been previously bored out during a rebuild.

Piston rings are essential for sealing the combustion chamber, controlling oil consumption, and transferring heat from the piston to the cylinder wall. Over time, these surfaces wear down, impacting engine efficiency and power. This set includes a full set of rings for one engine, providing a direct replacement for OE part number 4485572.060. Using the correct over-bore size ensures a proper seal and helps restore your engine's lost performance.

Installing these rings is part of a larger engine rebuild process. Make sure to consult your vehicle's service manual for the proper procedures and any additional parts or tools you might need for a complete engine overhaul.
