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.

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.
