RockJock's Heavy Duty High Steer Knuckle Kit for JK Wrangler and Unlimited vehicles provides everything needed to do the job! The components in this kit are specifically engineered to modernize your JK's steering and trac bar geometry to the improved specs. of a JL/JT, dramatically improving drivability as well as off-road performance. The new knuckles raise both the tie rod and drag link 2 3/4 in. as well as pushing the tie rod outward, away from the axle slightly, allowing for tighter (JL/JT) steering angle over that of stock JK and 1 ton axles. Currectlync steering that is included in this kit features a forged, organically shaped drag link for maximum up-travel and rigidity and a 42mm tie rod. All steering rod ends are forged steel and comparable to those found on modern 1-ton trucks. The included forged, organically shaped JL/JT trac bar's longer length pushes the trac bar adjuster joint outboard of the frame rail providing an additional 5/8 in. of up-travel! RockJock's fully integrated trac bar relocation and ram assist mounting bracket raises your trac bar mounting point 2 in. and corrects it's geometry to prevent bump steer, as well as providing you with a solid mounting point for a JL/JT spec. hydraulic steering assist ram (allowing for more steering radius). The bottom of the bracket acts as a skid plate, protecting the ram from rocks. A forged chromoly tie rod clamp installs to provide an easy hook-up point for the other end of your ram. All other factory outer components are retained with the new knuckles including outer axles, unit bearings, dust shields and brakes. The use of RockJock's RJ-107101-101 adjustable front bump stop kit is strongly encouraged to allow for maximum up-travel, as engineered.

Core 4x4 excels with precision and service and keeps nothing else higher in mind. Everyone I've met at the company is very honest and down to earth, 10/10 would recommend.

I broke a grease fitting off in my end link. I thought I was going to have to buy a new one. Reached out to Core 4x4 and wham! bam! They fixed it and sent it back with 2 day shipping. Got it a day early even. If they couldn't fix it they were going to send me a new one. Now that's customer service! They are now a permanent part of my garage. Thank you Core 4x4!

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.

I purchased the Jeep WJ control arms Camp series over a year ago. Very pleased and impressed. Easy installation and solid build. Bracket broke for rear upper control arm, they redesigned it to be more robust and sent me a new one with hardware, honoring their guarantee!

Got the CAMP version of adjustable control arms and track bars for our 03 TJ with a 3” lift and 33x10.5 KO 2’s. Super beefy bars, great fit and adjustability. Friendly advice and support from Korby at CORE 4X4. Good follow up as well. The ride quality is great as well as the handling. I think it all looks pretty good as well.

I don’t write reviews often, but Core 4x4 absolutely earned this one. I recently ordered leaf spring mounts and realized after the fact that I messed up my order. Totally my mistake. Instead of giving me the runaround or pointing at a return policy, Core 4x4 emailed me back and forth, worked through exactly what I was doing with my build, and made sure I ended up with the correct parts. That kind of customer service is rare these days — especially in the off-road world where a lot of companies stop caring once the order is placed. The parts themselves are exactly what you hope for: solid, well-made, confidence-inspiring hardware that looks like it belongs under a vehicle that actually gets used. You can tell these are designed by people who understand suspension geometry and real-world abuse, not just CAD screenshots. Mistakes happen — especially on custom or modified builds — and Core 4x4 handled mine like pros. Fast responses, clear communication, and a genuine effort to help me get it right. If you’re on the fence: don’t be. Core 4x4 is the kind of company you want backing your build — the kind that treats customers like fellow enthusiasts, not order numbers.

Great customer service. I got my front upper and lower control arms and hardware on Friday afternoon. It didn’t come with instructions so I called Core 4X4 and they immediately e mailed me the instructions. Also, the kit I got had the spacers missing so I called. It was late Friday by thus time but they took care of the issue first thing Monday morning and I got the spacers on Tuesday. Great company.
