Description

This set is specifically engineered for a 4.56 gear ratio, providing optimal performance for applications requiring increased torque and capability. Constructed with precision, this gear set features a 7.20-inch ring gear diameter, a 26-spline pinion, and utilizes 10 ring gear bolts for secure mounting. It is explicitly designed to fit reverse rotation Dana Spicer 30 axles, and importantly, does not require a crush sleeve for installation. This makes it a suitable option for axles that are not equipped with one, simplifying the installation process. This ring and pinion set is ideal for enthusiasts and professionals looking to upgrade or replace existing differential gears for enhanced performance and reliability. Whether for off-roading, towing, or general driving, the 4.56 ratio offers a good balance between acceleration and highway cruising capability.
