Rock Assault Front Axle Housing. Trail-Gear is proud to introduce the newest addition to the Rock Assault Axle Housing family, our Rock Assault Front Axle Housing. This exclusive axle design is the first in the industry to be released with all new parts. That's right, our axle housing is not made with 30-year-old used knuckle balls.
Our knuckle balls are forged from 1035 steel, making them much stronger than stock, eliminating closed or bent knuckle balls. 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 result is an increase of 0.375 Inch in ground clearance under the axle tubes.
The axle tubes are made from 0.3125 Inch thick 1020 DOM tubing with an outer diameter of 3.0 Inch. The short side of the axle tube has been lengthened by 3.0 Inch, making the axle IFS width, so there is no need to run wheel spacers.
The heavy-duty, press formed, 0.25 Inch plate steel center section is shaved to give you 0.75 Inch of additional ground clearance under the differential. The differential mounting surface is made from 0.5 Inch plate steel to ensure studs can not pull out, even under heavy loads.
Our housings are precision alignment checked using state-of-the-art, 3D digital imaging equipment to ensure that all Rock Assault Axle Housings are 100.0 percent straight and true.
The Rock Assault Front Axle Housing will come in your choice of bare tubes, with spring perches installed, or 3-link ready with a panhard bracket included. For an additional charge we can install an inspection cap making inspecting your front ring and pinion a breeze. Axle housing is shipped unpainted and lightly oiled to prevent rust during shipping and storage.
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! Includes high strength DOM axle tubes that engage 0.625 Inch further into the center section with 360.0 Degree gusset welded around the tubes on the inside of the housing.
