Artec Industries Ford SuperDuty front axle trusses deliver a revolutionary low-profile design. They take the years of race and recreational abuse of Artec's first generation of trusses and add additional strength and functionality. Their key feature is how the truss top now bends around the differential for a better fit and clearance, making them ideal for vehicles needing more up-travel or for those building low center of gravity vehicles. The overall low-profile design means your axle is stronger, sleeker, easier to fit into any vehicle, and less likely to interfere with vehicle components. Features: * 3/8 in. thick mild steel truss top and 1/4 in. mild steel ram mount and gussets * Precision CNC-cut and bent for great fitment * Truss has super low-profile allowing better clearance for oil pans * Truss spans entire length of axle for complete reinforcement of the axle tubes * Truss is reinforced using interlocked 1/4 in. thick gussets for maximum strength and easy assembly * Main interlocking gussets are wider than Gen1 trusses adding overall strength to truss * Internal gussets conform tightly to the contours of the differential allowing you to weld to it for additional strength and rigidity * Truss is clearanced for differential breather tube

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

Insufficient carrier bearing pre-load can result in premature bearing failure and ring and pinion failure in all differentials, and possible oil/air leakage issues in an air locker differential. ARB differential carrier shim installation drivers are professional service tools for installing/servicing common shim pre-loaded differentials. Most common Salisbury-style axle assemblies require the pre-load shims to be tapped into place to achieve the required pre-load during set-up. Tapping shims into a tight space from a single point on the outside edge of the shim can cause damage to the shim, rendering it useless, resulting in extra cost and labor. ARB's shim drivers are comprised of six different sized steel profiles designed to evenly distribute the installation force around the outside edge of a differential shim as it is tapped into place, allowing thinner shims to be inserted into tighter places than would otherwise be possible.
