Trail-Gear, Inc introduces a new concept to 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. Axle
tubes are made from ¼” thick DOM 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 ½” 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 alignment checked using start-of-the-art, 3D
digital imaging equipment.
The
Rock-Assault axle housings use stock or aftermarket
1986-1995 Toyota Pickup/4Runner axle shafts. An
optional fill / inspection cap can be installed for an
additional fee. Additional lengths as well as front
applications will be available soon.
Overall
housing length is 51 3/8" 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 silicon are included and
are recommended for use with this axle. Unpainted bare-metal,
oiled finish to prevent rusting. We recommend
degrease housing inside & out before installation and
painting.
 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!

bracket can be purchased for $99. This bracket is
designed to accommodate 1.25"

upper link mount kit can be ordered loose as a do-it

to fit the Trail-Gear Rock Assault rear axle housing and
will not fit a factory stock rear housing. This product
is not compatible with the Trail-Gear "Creeper
