Description

The USA Standard Ring & Pinion gear set provides a 5.13 ratio upgrade for your Dana 30 reverse rotation differential. This replacement set is engineered for durability and performance, featuring a 7.20" ring gear diameter and a 26-spline pinion. Designed specifically for reverse rotation Dana Spicer 30 axles, this gear set does not utilize a crush sleeve, simplifying installation in certain applications. It requires 10 ring gear bolts for secure mounting. This USA Standard gear set is a direct replacement, offering a precise fit and reliable performance for rebuilding or re-gearing your differential. Ensure compatibility with your specific Dana 30 axle configuration before installation.
