Revolution Gear & Axle Ring & Pinion Set for GM & AAM 11.5" 14-Bolt (4.56 Ratio)

This is a 4.56 ratio ring and pinion gear set for the GM and AAM 11.5-inch 14-bolt axle, the heavy-duty rear used in GM 2500/3500 and Dodge/RAM 2500/3500 trucks. It is the gear set itself, cut to restore proper gearing.

The set uses a standard-rotation 30-spline pinion on an 11.5-inch ring gear with a 14-bolt cover pattern and is listed with no carrier break. Gears are machined from 8620 steel, heat treated and lapped for a strong, quiet setup that holds up under load.

A 4.56 ratio suits heavy 3/4- and 1-ton trucks running larger tires that need their gearing brought back for towing, hauling and off-road use. Because this fits by axle, it covers a range of GM and RAM applications using the 11.5-inch 14-bolt.

This listing is the gear set only. Pinion and carrier bearings, crush sleeve, shims, pinion seal and cover sealant are not included, and a carrier or locker is separate. Add a Revolution 11.5-inch master install kit for the bearings, and have an experienced installer set the pattern, backlash and pinion depth.

Confirm you have the 11.5-inch 14-bolt and not a different heavy-duty axle before ordering. With the right install kit and setup, this Revolution set is a durable regear for the popular 11.5-inch axle.
