If you want to run 32 or 33" tires without having to do major modifications, then this is the kit for you. These TJs are not getting any younger and more parts are needing to be changed in order for your Jeep to handle properly. This complete system is made to handle great off road as well as ride far better than stock on road. This isn't a spacer kit, but rather an engineered suspension system. Fox Adventure Series Shocks are specifically valved for your TJ, then a matching Fox stabilizer is added. Your factory track bar is whooped, and the cause of 75% of deather wobble issues so we include a stronger Adjustable Track Bar along with all 4 lower control arms and new hardware for everything you need. When compared to your stock TJ, this kit increases droop by 4-3/4" and increases the wheel travel from the stock 7" to 10 full inches of wheel travel! The true performance of this system is attributed to the coil springs. These springs are design to handle all the abuse you can throw at them and still hold their original height.
