Toyota Rock Assault Rear Axle Housing
Improve Your Ground Clearance And Increase Your Axle's Strength
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.This is Trail Gear part #140187-1-K.
