Trail-Gear Rock Assault Front Axle Housings
Trail-Gear Rock Assault front axle housings give you clearance to go where you want and the muscle to do it! Their strength comes from heavy-duty, press-formed, 1/4 in. plate steel center sections; 1/2 in. plate steel differential mounting surfaces; 5/16 in. thick 1020 DOM axle tubes; and forged 1035 steel knuckle balls. Trail-Gear's knuckle balls are stronger than stock, so there are no worries of them becoming closed or bent. And, the thicker differential mounting surface ensures that the studs cannot pull out, even under heavy loads. Trail-Gear's design—offset tubes and shaved center section—provides you with added clearance to climb the high country. Plus, since housings are precision-aligned with computer imaging, you can rest assured they're 100 percent straight and true. You have a choice of bare tubes, or with spring perches installed—or 3-link ready with a panhard bracket included. You're equipped to attack any terrain with Trail-Gear Rock Assault front axle housings.

They combine the smooth operation of a limited-slip differential with the traction performance of a locking differential.

Only ultra-strength material that is 67 percent stronger than titanium is used. Installation is simple because no ring and pinion setup is required. In addition, no special tools or oils are needed. Step-by-step, model-specific instructions are provided with every kit.

Artec Industries 14-Bolt Rear Apex Short Axle Trusses
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.
