Revolution Gear & Axle Master Install Kit for GM (2001-11) & Dodge (2003-10), AAM 11.5" Rear Axle

This is the Revolution Gear and Axle Master Install Kit for the AAM 11.5 inch rear axle found in GM 2001-11 and Dodge 2003-10 heavy-duty trucks. It supplies the bearings and small parts needed to properly overhaul the differential when installing a new ring and pinion.

The kit uses Timken carrier and pinion bearings and includes a crush sleeve, carrier and pinion shims, pinion seal, ring gear bolts, and cover gasket/silicone. That covers the consumables a tech needs to set backlash, pinion depth and preload to spec on this big AAM rear.

It is the right choice for anyone re-gearing an 11.5-equipped 2500 or 3500, whether you are dropping ratios for tires and towing or simply rebuilding a high-mileage rear axle.

Note the exclusions: this kit does not include the ring and pinion gears, and it does not include axle seals or axle bearings. Plan on a separate Revolution AAM 11.5 ring and pinion set, and order axle service parts if you are pulling the shafts. Gear setup is precision work best handled by an experienced installer.

Matching the install kit to your gears is the cleanest path to a quiet, durable rear end that holds up to heavy towing and daily work.
