Description
Rock Assault™ Rear Axle Housing – IFS Width
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 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 aligned 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.
Overall housing length is 51 3/8 mounting flange to mounting flange. Empty housing is 54 . 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 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 W.E.Rock Formula Toy Series. Thanks Jason!

- We recommend the addition of our Axle Housing Inspection Hole Kit to allow for easy fluid level and ring gear visibility. Just select With Inspection Hole Kit Installed in the drop down menu above. The kit is also available in a DIY installation version (requiring drilling through the differential housing and welding on a threaded bung).
- In order to achieve full ground clearance, you will need to grind the bottom of the differential housing flange flush with the axle housing!
