RockJock's Geometry Correction Axle Bracket Kit for the rear Trac Bar of 2021-up Broncos is a highly recommended upgrade for lifted vehicles to relocate the axle housing mounting point of the rear trac bar upward, correcting the location of the trac bar mounting point. You’ll find this bracket necessary on lifted vehicles that feature heavy additions above the roof or behind the tailgate. The addition of this bracket will restore rear suspension lateral geometry and produce better overall vehicle handling by raising the rear suspension roll center to bring it closer to the vehicle’s center of gravity. This kit is completely bolt-on, works with factory or aftermarket trac bars, such as our RJ-183400-101 Johnny Joint adjustable trac bar) and very simply installs onto the factory axle housing. A rear brake line relocation tab is included to provide clearance for the new trac bar bolt location. Bracket is finished in semi-gloss black and includes all necessary hardware for installation.

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

Solid product, the lifetime warranty sealed the deal for me. Installed on my TJ and the ride quality improved noticeably. Shipping took a bit longer than expected but the parts were worth the wait.

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.
