As soon as the first Jeep Wrangler Unlimited rolled off the assembly line and hit the pavement, aftermarket manufacturers began designing parts to accentuate the vehicle's off-road prowess. With a wheelbase 12 inches longer than that of a standard TJ, it was obvious that builders would have some redesigning to do. The smart ones, though, simply took their best TJ parts and looked at how to make intelligent modifications that would make them work with this new rendition of the Wrangler.
This is precisely what the engineers at Full-Traction Suspension decided to do with their popular 6-inch Long-Arm Kit. This bolt-on suspension lift uses a genuine three-link system in the rear, which pivots on a high-misalignment uniball joint. This setup completely eliminates the need for a rear track bar, which can bind and limit linear wheel travel and axle articulation. The more traditional four-link frontend is equally well-designed and has been built to maintain correct castor curve throughout the range of wheel travel. To withstand constant trail abuse, the lower arms are constructed of 2x0.250-inch-wall DOM tubing, and the plates and brackets are all made of laser-cut 1/4-inch steel.
As it turned out, R&D testing showed that the modifications required to make the kit work with the Unlimited were minimal, which was great news because this suspension worked so well. If you're looking for ways to turn your new Wrangler Unlimited into a tough trail machine that you can take over the meanest obstacles and still drive on the highway at 60 mph, take a close look at Full-Traction.
