Rock Krawler 4.5" T-REX Suspension System for Jeep Wrangler JL (Gas Models)
The Rock Krawler Suspension T-Rex Hybrid Long-arm Systems are the absolute best combination of on-road ride/handling and off-road ability you can get for your Wrangler JL 2 Door when keeping the gas tank in the stock location. Don’t shoot the messenger here, but Jeep killed the availability of putting full long arm systems in the front end of 2018 and newer 2 door applications due to the new fuel tanks that go up and over the crossmember all the way to the OEM front lower control arm mount on the frame. We promise it was not our idea! This vary fact is what made us create the Hybrid T-Rex System. The T-Rex is a full high clearance mid-arm front setup with our tried and true ultra high clearance 3 link rear conversion. This gives you the absolute best possible combination to enhance your 2 Door Wrangler Off-Road. The stock front suspension geometry on JL/JLU applications is really not terrible and is workable. The rear suspension geometry being a parallel 4 link with a track bar (i.e. 5 link rear) is really where the lack luster performance comes into play. This suspension arrangement naturally binds causing jacking when being tasked to perform off road. The Rock Krawler ultra high clearance 3 link with track bar removes the natural binding of stock rear suspension 100% allowing for ultra smooth suspension motion in the rear without jacking. A night and day difference. You also get the benefit of X2 rear suspension geometry gaining 4.5” of ground clearance under the rear axle without losing a single centimeter of rear shock travel! The rear roll center is raised significantly to further enhance handling and reduce side to side axle shifting while off-road. Make no compromise suspension geometry wise is our motto and T-Rex is no exception. All T-Rex control arms feature our exceptionally proven Adventure Series Joints for years of maintenance free use!
