Artec Industries JK 1 Ton APEX Rear 14-Bolt Truss Swap Kits

Artec Industries JK 1-ton APEX rear 14-bolt truss swap kits feature patent-pending trusses that go to a whole new level of strength, weight savings, simplicity of installation, precision fitment, and complete axle protection. Artec Industries JK 1-ton APEX rear 14-bolt truss swap kits are advanced truss and bracket systems which can be used for AAM 14-bolt 10.5 in. ring gear. The kits provide the factory link, track bar, spring, anti-sway bar, bump stop pads, and shock locations all encompassed in an axle tube reinforcing truss system. Features: * CNC precision laser-cut in-house from 1/4 in. and 3/16 in. mild steel * Lightweight yet strong ... only 42 lbs. total * CNC precision bent in-house for a great fitment--literally drop the truss in place on the axle and it's ready to weld * Designed used 3D models directly from Ford and Jeep for not only an amazing fit but clearances with surrounding components * 70 percent less welding needed than previous truss designs means 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 * 2-piece truss design means smaller packaging with easy installation * Using a 1 ton axle will support larger tires and less chance of breakage in extreme conditions * Coil brackets and bump stop pads are combined to form an axle tube truss and allows for easy installment of other brackets * Save hours of installation time with the built-in axle tube truss which is quicker to weld than individual brackets * Track bar mount includes four locations for those who have aftermarket lifts. Stock height hole is not included though * Coil spring locator is machined from solid steel making welding to bracket quicker than previous tube and cap-style locators * Shock brackets have been moved up for a slightly higher clearance lower control arm bracket * Easily upgradeable for future link geometry changes. Just trim off factory location upper control mounts and weld on a center link mount
