Show original supplier description

The Yukon Gear and Axle YG D30R-488R is a high-performance ring and pinion gear set engineered as a direct replacement for Dana 30 reverse rotation differentials without a crush sleeve. Yukon has optimized the gear tooth surface finish to actively reduce friction and heat buildup during operation. Key specifications include a 4.88 gear ratio, a 7.20" ring gear diameter, a 26-spline pinion, and it requires 10 ring gear bolts and 10 cover bolts for installation. This ring and pinion set is intended for applications requiring a specific gear ratio for enhanced performance, such as larger tire fitment or improved torque for off-road use. Installation typically requires specialized tools and knowledge of differential setup.
