Rock Assault™ Samurai Rear Axle Housing Kit





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, 1/4″ plate steel center section shell that is specially shaped to ensure a minimum of 3/4″ additional clearance under the differential. The differential mounting surface is made from 1/2” 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 1/4” thick DOM tubing, with a 3” 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 3/8″ 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.

The Samurai Rock-Assault axle housings use stock or aftermarket 1986-1995 Toyota Pickup/4Runner brake backing plates and brake assemblies and uses a custom length chromoly axle shaft that Trail-Gear is also very proud to manufacture.. An optional fill/inspection cap can be installed for an additional fee.

Overall housing length is 51 1/2 inches from mounting flange to mounting flange. Axle is shipped unpainted and lightly oiled to prevent rusting. We recommend degreasing housing inside and out before installation and painting.

This housing uses a Toyota 8″ differential.
