Axle Housing Kit Rear IFS Width. 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 heavy-duty, press formed, 0.25 Inch plate steel center section shell is specially shaped. The differential mounting surface is made from 0.5 Inch plate steel to ensure 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. Overall housing length is 51.375 Inch mounting flange to mounting flange. Empty housing is 54.0 lbs. Spring perches, shock mounts, and vent not included.
Differential stud kit and RTV silicone are included and are recommended for use with this axle. Unpainted bare-metal, oiled finish to prevent rusting. We recommend that you degrease the housing inside and out before installation and painting. The original design concept for this axle was created by Jason 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! All rear Rock Assault Axle Housings utilize an 8-Inch differential. 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 Do It Yourself installation version which requires drilling through the differential housing and welding on a threaded bung, as well as a factory-installed version.
In order to achieve full ground clearance, you will need to grind the bottom of the differential housing flange flush with the axle housing! The axle tubes have been offset above the housing centerline, so the inner axles ride near the bottom of the axle tubes rather than in the center.
The Rock-Assault axle housings use stock or aftermarket 1986-1995 Toyota Pickup and 4Runner axle shafts. An optional fill inspection cap can be installed for an additional fee.
