Skyjacker's Platinum Coil-Over Rock Ready 8-inch Jeep Unlimited system re-engineers the TJ's suspension geometry via an integrated subframe assembly. An 80-percent increase in the length of the lower control arm produces an unprecedented amount of articulation with no more than 1.5 degrees of caster change. A new driveshaft and replacement CV, as well as modifications to the factory exhaust crossover pipe, will be necessary. Contact: 318/388-0816, www.skyjacker.com
Race Car Dynamics makes a variety of Jeep suspensions, including the 3- to 4-inch suspension system for '87-'96 YJs shown here. The system includes progressive-rate leaf springs that are individually shot-peened and powdercoated for corrosion resistance. The system uses nylon anti-friction pads on all leaves, and open spring clamps to reduce friction and improve flex. Polyurethane bushings provide increased performance and long life. An integrated-degree shim is built into the rear spring for proper pinion angle. The kit also includes front and rear bumpstop relocation pads, extended sway-bar links, front and rear Panhard bar relocation brackets, and four custom-matched Bilstein 5100 series monotube gas shocks.

Currie manufactures the Johnny Joint Suspension system with heavy rear springs for the TJ Wrangler. The kit includes an Anti-Rock Swaybar with a heavier-rate rear spring for hardtop or heavy load applications. The anti-rock kit with aluminum arm option provides balanced performance of front and rear suspension for rugged off-pavement conditions. The aluminum arm is lightweight, adding traction by distributing weight over all four tires. The sway bar is made of SAE 4130 and is heat-treated. It incorporates Johnny Joint rod ends that supply 30 degrees of free movement. Bushings are of high-density urethane. The ball is heat-treated steel, and cross-drilled for through-bolt lubrication. The outer shell is 0.180-inch DOM tubing; retaining washers are heat-treated steel. Contact: 714/528-6957, www.currieenterprises.com
The new Full-Traction "Ultimate Jeep TJ 4" suspension provides adjustable four-link front axle mounting for a true and correct front axle caster curve throughout the entire range of linear axle travel. The rear axle is attached to an upper triangulated link bar using an unique bolt-on truss mount, and pivots on a high-misalignment, adjustable Heim joint. This eliminates the need for a rear-axle track bar. The result is substantial linear wheel travel and axle articulation, without binding caused by the rear track bar. The geometry of the rear triangulated link eliminates chassis "yaw" and adds to stability at freeway speeds. Components in this system use 1.5-inch by 0.188-wall DOM tubing for the lower control-arm assemblies for serious rock dragging, and 1/4-inch plate, laser-crafted brackets throughout. Grade 8 quality plated hardware provides corrosion resistance and long service life. It is said to be fully bolt-on, with no welding required. Contact: 661/398-9585, www.full-traction.com
Mountain Offroad Enterprises carries long-travel shock kits, body lifts, shackle systems, and other suspension pieces, available in kits or separately, for a wide variety of Jeeps. Shown is a bolt-on shackle reverse system that incorporates a "buggy spring" to act as a normal shackle mount in everyday driving situations. The springs are mounted so they can pull away from the frame to add as much as 2 inches of articulation. The system provides a 1-inch lift at the front by itself, or can be used with other aftermarket lifts up to 4 inches. Contact: 970/625-0500, www.mountainoffroad.com
Fabtech's 6-inch kit for TJs uses extended-length link arms that mount to a massive one-piece welded transfer-case crossmember that uses the stock transfer-case skidplate. The kit includes adjustable front and rear track bars, shock-mount relocation brackets, pitman arm, oversized sway-bar quick disconnect links, brake hoses, and performance coil springs. The 6-inch system will allow use of a 35x12.50R15 tire on a 15x8 wheel. Contact: 909/597-7800; www.fabtechmotorsports.com
