Description

The USA Standard Gear Dana Spicer 30 Axle Ring and Pinion Gear Set offers a reliable solution for restoring or enhancing axle performance in your Jeep Wrangler TJ. Engineered with a 4.88 gear ratio, this set is designed to bring your vehicle's powerband back, providing optimal performance for both demanding off-road excursions and daily driving. This gear set features a 7.20" ring gear diameter, a 26-spline pinion, and 10 ring gear bolts. It is specifically designed for Dana Spicer 30 axles that utilize the Crush Sleeve Design and a Short Pinion configuration. The robust finish is built to withstand heavy-duty use while minimizing noise levels, contributing to a quieter driving experience. Installation of this ring and pinion gear set requires moderate mechanical knowledge. It is intended for standard rotation differentials.
