Beef up your rear-end with Trail-Gear Rock Assault rear axle housings. Better trail performance comes in the shape of fabricated, thick steel center sections and differential mounting surfaces, heavy-duty DOM axle tubes, and 4130 chromoly flanges. Plus, Trail-Gear engages the tubes further into the center section, with a 360 degree gusset welded around the tubes on the inside of the housing, to ensure that your rig is strong enough to go wherever you want! Rock Assault's overall design also offers additional clearance under the axle tubing and differential, providing more height to climb over those big boulders. Outfit your rig to be extremely tough with the rugged, high-clearance design of Trail-Gear Rock Assault rear axle housings.

Years after releasing their successful Rock Assault 9 axle housing, Trail-Gear decided to add a Toyota 8 in. version to the Rock Assault lineup. This housing is built to the same specifications as the Rock Assault 9 axles; however, they're built to accept the popular Toyota 8 in. differential. These housings have been tested in W.E. Rock, CalRocs, and King of the Hammers—so you know they'll stand up to the toughest terrain on earth. Trail-Gear started with a 1/4 in. thick formed shell for the center section made from A36 steel. This is a high-strength, low alloy, structural steel plate with a minimum yield strength of 36,000 psi. All of this is attached to an equally strong 1/2 in. thick faceplate for anchoring the DOM axle tubes. The axle tubes are secured by the industry's first 3-Point Attachment System, giving the tubes superior support and engagement into the center section. Trail-Gear also faces the center section to ensure your differential mounts flush against the axle housing to prevent any leaks. Rock Assault Fabricated 8 Housings are offered with 3.5 in. O.D. axle tubes with your choice of 1/4 in. or 3/8 in. wall thickness. NOTE: The housing is shipped with no ends. Housing ends must be sourced and installed to complete axle. Portal style ends are commonly used for this application.

Trail-Gear assembled Super Finish third members are made from tool-grade 8620 steel and heat-treated for maximum strength and wear resistance. They include all new parts and are ready to drop into your axle with top-quality Super Finish 29-spline ring and pinion gears, and your choice of locker. The ring and pinion gears are treated with the REM Isotropic Super Finishing (ISF) process, which removes the microscopic peaks in the material and creates a surface on the ring and pinion gears with a roughness of less than 10 µin Ra. This means that there is less friction between the gears, reducing wear by 95 percent, and allowing the gears and bearings to run cooler and last longer. Select the ideal kit for your application. Additional features and benefits: * Fully built Super Finish 3rd members--all new parts--no used housings or internal components * 29-spline pinion spline is 7 percent larger in diameter than the 27-spline for increased strength * Available in 4.88 and 5.29 ratios for 4-cylinder, V6, and high-pinion applications * Gear teeth are cut using Gleason CNC hobbing machines and cutters * No break-in period * Non-directional surface that increases lubricant retention on the gear surface, reducing lubrication requirements * Dust shield pre-installed onto flange * High-pinion sets also include a high-pinion oil slinger * V6 units feature larger OEM-style V6 gear sets with a longer pinion gear * Trail-Safe pinon seal and nut included * Flange is quadruple drilled with popular Pickup/4Runner and Tacoma patterns: -- 66mm x 66mm x 11mm (Tacoma) -- 60mm x 60mm x 10mm (Pickup/4Runner and TG heavy-duty driveline) -- 60mm x 68.3mm x 10mm -- 61.5mm x 70mm x 10mm Notes: * Requires ring and pinion setup kit to complete the installation into your existing differential housing * For Toyota 8 in. solid axles only.
