Differentials, Axles & Rear-End Parts

Ford Performance Parts Axle Girdles

Ford Performance Parts axle girdles are a great way to strengthen the rear-end of your car. Made of lightweight aluminum, they incorporate load bolts that provide additional support for differential bearing caps. Because they reduce the amount of flex in your differential while under load, they significantly reduce bearing wear and chipped teeth on the ring and pinion. They provide increased ring and pinion gear life and are a definite must for all racing and high performance street cars. Additional information: * Available for a variety of applications, including some independent rear suspensions * Replaces OE rear cover * Covers with cooling fins and machined for differential cooler pickup and return fittings recommended for road racing or extended high-speed/high-temperature applications * Models equipped with differential coolers may require modifications * Check exterior clearance to chassis/suspension

BD Diesel Differential Covers

BD Diesel differential covers are cast to cool. Specially engineered, the powdercoated aluminum covers are designed with internal and external cooling fins, plus an extra-capacity bottom sump. This strategy allows gears to pick up and deflect oil back onto the ring gear and into the pinion gear for cooler, longer life. BD Diesel differential covers are gasket-less, and each includes a reusable Viton® O-ring, stainless steel Allen head cap bolts, fill plug, and magnetic drain plug for a complete, easy, and "cool" installation.

Trail-Gear Assembled Super Finish Third Members

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. Will not fit 7.5 in. IFS front axles.
