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.

A 4x4 and traction go hand-in-hand; however, standard (open) differentials allow each wheel to turn independently to eliminate binding in turns. Off-road, this becomes a problem as engine power takes the path of least resistance—to the wheel with little or no traction. Limited slip differentials offer some improvement, but too often the slipping is not "limited" enough to maintain forward progress. Automatic locking differentials also have disadvantages; noisy when disengaging, they can also upset on-highway driving characteristics. Created to provide traction on demand, without sacrificing highway driving performance, ARB Air Locker differentials employ a 12 V ARB air compressor (sold separately) to pneumatically operate a solid and durable locking mechanism inside the differential. When activated, the Air Locker prevents the differential gears from rotating and the axle shafts from turning independently of each other. With both wheels tied directly to the rotation of the ring gear, the vehicle maintains maximum possible traction at all times. When unlocked, it operates just like a conventional open differential. ARB Air Lockers are available in over 100 configurations for a wide range of vehicles and can be installed in both front and rear axles. Installation should be performed by a qualified differential technician, although no special tools or skills are required, apart from those necessary for fitting a standard differential. ARB also offers three compressor models suitable for Air Locker operation, two of which can be used to inflate tires and operate other equipment. Additional features of ARB Air Lockers include: * Vastly improved traction means less reliance on momentum, reducing the likelihood of vehicle damage * Easy, convenient operation without leaving the comfort and safety of the driver's seat * Ultra durable and extremely strong; only the highest quality materials used in construction * Patented gear technology and 2-piece design ensures optimal locking strength * Forged gears provide superior strength and durability * Incredibly simple, yet effective, design employs minimal moving parts for maximum reliability * Thoroughly tested and proven * Most sold as kits with differential, activation switch, solenoid valve, air line, and bulkhead fittings * Front and rear Air Lockers available for most makes and models * For 4WD and 2WD applications * Easy maintenance; no special additives required * Also offered in ARB Traction Packs that include two Air Lockers, a compressor, and accessories for tire inflation
