The axle tubes are now made from 5/16" thick, high strength DOM
tubing and engage 5/8" farther into the center section. On top of that,
there is a 360° gusset welded around the tubes on the inside of the
housing to ensure unparalleled strength.
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 results are an increase of
3/8" ground clearance under the axle tubing.
The heavy-duty, press formed, 1/4" plate steel center section shell
is specially shaped to ensure a minimum of 3/4" additional clearance
under the differential. The differential mounting surface is made
from ˝” 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 53 1/4" mounting flange to mounting
flange. Empty housing is 54 lbs. Includes drain plug. 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
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
We-Rock F-Toy Series. Thanks Jason!
Note: All rear Rock Assault™ Axle Housings utilize an 8" differential
