Rock Assault Tacoma Rear Axle Housing. Trail-Gear introduces a new concept to the axle housing design. This exclusive design features axle tubes that have been offset above the housing centerline. The inner axles ride near the bottom of the axle tubes rather than in the center.
The differential mounting surface ensures studs can not pull out, even under heavy loads. The outer offset flanges are made from 4130 Chromoly to prevent distortion or bending. Housings are precision aligned using start-of-the-art, 3D digital imaging equipment.
We recommend the addition of our Axle Housing Inspection Hole Kit to allow for easy fluid level and ring gear visibility. The kit is available in a DIY installation version which requires drilling through the differential housing and welding on a threaded bung, as well as a factory-installed version.
The original design concept for this axle was created by Jason Locktup Stanley. This rugged, high clearance design proved to be extremely tough and helped Team Trail-Gear win first place in the 2007 W.E.Rock Formula Toy Series. Thanks Jason!
