This Trail system provides enhanced suspension performance to address all variants of off highway travel use including rock crawling, aggressive trail use and overland expeditions. On road, the suspension has been tuned with proper dual rate coil springs and shock valving to provide a very compliant ride that you will appreciate. The system is a complete short arm suspension that utilizes the factory control arm mounts for an easy installation. The Fabtech heavy duty link arms are constructed of 1.75&quot OD. .250" thick wall steel tubing that are guaranteed never to bend. They come with large poly urethane bushings on one end with internal threads on the other to accept the ground breaking Fabtech 5 Ton Joint? for longevity and a quiet ride. Fabtech?s long travel Dual Rate coil Springs are corner specific to the JL. This keeps the vehicle level side to side and allows for increased suspension travel. To address the steering geometry with the increased ride height, a Draglink Flip System along with a heavy duty Track Bar bracket is included. This relocates the steering geometry to the factory plane allowing for full articulation without binding the draglink ends in extreme conditions. The factory angle of the draglink to the pitman arm does not change and there is no increased side load on the steering box sector shaft as compared to using a dropped pitman arm. This helps extends the life of the steering box with the increased ride height. The heavy duty rear Track Bar bracket with side support maintains the factory roll center of the vehicle while centering the axle. Front and rear bumps stop extensions protect the suspension from over cycling. This popular system is a top choice for daily drivers that enjoy tackling tough trails and overlanding with the comfort that they have a high quality complete suspension under their Jeep.
