The TeraFlex 4" Lift Suspension System w/ Eight (8) Adjustable Alpine Flexarms & Track Bar for the Jeep Wrangler JK Unlimited 4-door offers the Ultimate Suspension components needed to lift your JK Unlimited and get your Jeep capable of experiencing the off Road excitement of overcoming those larger obstacles, or to surmount the most challenging trails and extreme All Terrain circumstances. Included in the kit are the Teraflex Alpine Flexarms and Track Bar. The Track Bar is a heavy-duty forged adjustable front track bar. The Alpine Flexarms are designed to give your Jeep Wrangler JK the ultimate off-road articulation and ride comfort.

This kit allows you to fine tune your suspension by giving you the ability to add you own choice of shocks and the adjustable components help to customize the handling of your Jeep.
