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.

Their website estimated 2 days to get my parts but actually took 11. No communication to let me know what’s going on. Parts were missing. Some days they answer questions, some they don’t. Didn’t let me know I’d have to alter stock bolts to fit their parts.
All around just seems like they don’t care.

I have a 2016 RAM 1500 Crew Cab and I replaced the rear upper and lower control arms also the pan hard track bar and also the sway bar and links for the rear with all I had the articulating bushings. The vehicle now has no body role. They are absolutely incredible if you get the control arms you gotta get the CORE 4 x 4sway bar end links don’t don’t try and be cheap and get Moog or something else you got to get articulating bushings get the core 4 x 4 ones they are the best. My truck drives now through the canyons like a BMW. I have Fox high-performance shocks on there as well with all the CORE 4 x 4 suspension parts and they are amazing. Well worth the money I would highly recommend anybody thinking about CORE 4 x 4 go with CORE 4X4 and if you can go with their articulating bushings, they’re unbelievable drives better now than my Escalades. Well planted no body role and smooth on the Highway unbelievable the difference they all made!!
THANKS AGAIN CORE 4x4!!!!

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.

Korby was extremely helpful in helping me find the right part for my truck. He was kind, knowledgeable, and patient while I asked a million questions. He also went out of his way to find the right shipping option for me since it’s tricky where I live. I’m looking forward to getting the parts so I can fix my truck and go adventuring again soon!

First and foremost would like to say that Core4x4s customer service is top notch and they definitely stand behind their warranty on products! Highly recommend using them for any of your off road needs! It’s rare to find a company now a days that backs their products and they do!
Had a few issues with mounts and control arms and they handled it without hesitation! Thank you!

Great long arm kit with everything else I needed as well! They worked with me to ensure that I was getting an upgraded components kit just like I wanted. Fast shipping with some of the best packaging that I have ever seen. Nothing was scratched or missing and this kit is even more impressive than the videos or website can show. Powder coating looks great with no issues.
I would highly recommend CORE 4x4 to anyone looking for a great quality kit.
