RockJock's Trac Bar Relocation and Ram Assist Mount Axle Bracket Kit for JL Wrangler, JL Unlimited and JT Gladiator vehicles is designed specifically to be used in conjunction with our High Steer Knuckles. This integrated trac bar relocation and ram assist mounting bracket raises your trac bar 2 in. and corrects it's geometry to prevent you from incurring any bump steer as well as giving you a solid mounting point for your hydraulic steering assist ram. The bottom side of the bracket provides a skid plate that protects your ram from rocks. The large axle bracket, as well as the small bracket for use on the driver’s side of the axle to relocate the sway bar end link mounting point, easily install, but do require some minor welding. However, both brackets can be mounted solidly enough with the bolts to allow you to drive to a welder if need be. We recommend buying this bracket in our complete RJ-440000-101 High Steer Knuckle Kit so that you are ensured a complete system that includes everything you need to get the job done. The use of our RJ-9120FJLF forged, organically shaped front trac bar is also strongly encouraged, so that all components nest together for maximum up travel as engineered.

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.

Great company! I have used there products consistently with no complaints with quality you can see and feel. From my experience, their customer service is also amazing. Core 4x4 has no issues standing behind their already amazing products and will quickly and professionally solve issues may they arise. I will continue to be a customer.

The parts are a massive improvement over factory. I accidentally ordered the wrong endlinks and they helped me figure out the correct size and sent me new ones.
Definitely an awesome store

To start off if you're looking to upgrade your control arms definitely hit this company up. Great product, easy install of the product, with three different tiers everything is priced pretty good, I'm a sticker guy and they sent a sticker for each arm each track bar and also three extra ones so the extra are on the Jeep the advertise them for sure. If you're reading this review I highly recommend you to check their website out.

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.
