Differential Install Kits for Re-Gear & Axle Builds

Differential Install Kits for Re-Gear & Axle Builds

Differential install kits supply all the hardware required to correctly set up a new ring-and-pinion gear set during a re-gear, including pinion bearings, carrier shims, pinion seal, crush sleeve, marking compound, and ring gear bolts. Buying a matched install kit ensures proper gear mesh, preload, and backlash settings that are critical to differential longevity and noise-free operation.

Popular Differential Install Kit Applications

Install kits are available for nearly every popular axle including Dana 30, Dana 44, Dana 60, GM 7.5-inch, GM 8.5-inch, GM 10.5-inch, Ford 8.8-inch, Ford 9-inch, and Chrysler 8.25-inch and 9.25-inch differentials. Yukon Gear, Motive Gear, and Richmond Gear are common brands trusted by professional builders for accurate preload specs.

Do I need a master install kit or a standard install kit?

A standard install kit covers the basic bearings, seal, shims, and hardware needed for most re-gears. A master install kit adds carrier bearings and races, making it the better choice when installing a new carrier, locker, or limited-slip unit at the same time as the ring and pinion.

Can I reuse old shims from my differential?

Old shims can sometimes be reused if they are undamaged and the carrier has not been changed, but installing fresh shims from an install kit gives you a clean starting point for accurate backlash setup. Most professional builders recommend new shims any time the differential is opened.
