Artec Industries patent pending 14-bolt rear Apex short axle trusses feature a stronger design, lighter weight and are much easier to install. The key feature that sets them apart from the other brands is their unique peaked-shape top which provides extra rigidity to the whole truss, while allowing both a reduction in weight (vs. using a thicker material top) and eliminating long weld seams. Previous truss versions with long weld seams can lead to extra weld warping of the axle, longer install times and can be inconsistent. Without long seams to weld, the 14-bolt rear Apex short axle trusses can be dropped directly on to the axle, and then these trusses can be welded to the axle faster. Additional part features: * Designed using 3-D models directly from Ford and Jeep for an amazing fit and clearance with surrounding components * CNC precision-cut in-house from 3/16 in. mild steel for a lightweight yet strong solution * Patent pending Apex peaked top design provides more rigidity than a flat top truss design * CNC precision bent in-house for a great fitment * Installation is simple; literally drop the truss in place on the axle and it's ready to weld, no puzzle piece assembling * 70 percent less welding needed than previous truss designs mean less warping, faster turnaround, and lower costs * All long seams are bent so you don't need to spend time welding them together * Dimpled holes provide not only weight reduction but rigidity and strength * Contours both the cast steel differential and can be welded with normal MIG welder and moderate pre-heating and post-heating * Truss is low-profile allowing link joints to be mounted with ideal geometry—about 9 in. from the axle centerline * Truss is designed to fit in between leaf springs or can be used as a base for mounting link suspension mounts * 2-piece design means smaller packaging and less shipping costs along with easy installation Important note: Requires general welding and fabrication skills. Welding should only be done by a competent welder. Artec Industries implies no guarantees or warranties and is not liable for improper installation. Some grinding and fitment may be required when installing this item. Every axle varies slightly, and some fabrication may be required.

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
