Rock Assault Samurai Rear Axle Housing Kit. Trail-Gear is proud to introduce The Strongest Samurai Axle Housing Ever Made. The Samurai Rock Assault Axle Housing Kit is a Toyota IFS width axle housing that is offset for a Samurai t-case. This housing features a heavy-duty, press formed, 0.25 Inch plate steel center section shell that is specially shaped to ensure a minimum of 0.75 Inch additional clearance under the differential. The differential mounting surface is made from 0.5 Inch plate steel and comes with our Differential Stud Eliminator Kit to ensure that your differential never pulls out of the housing.

The outer offset flanges are made from 4130 chromoly to prevent distortion or bending. Axle tubes are made from 0.25 Inch thick DOM tubing, with a 3.0 Inch outer diameter. 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 0.375 Inch ground clearance under the axle tubing. The center section is offset to line up with the Samurai t-case so that your driveline does not vibrate from being offset.
