RockJock's completely bolt-on Currectlync Steering System eases some of the pain of installing a JK front axle in your TJ, LJ, XJ, MJ or ZJ! The axle swap can be tricky, but it’s doable. But, what do you do for steering? Here is your solution! Features include an alloy steel 42mm, 1.65 in.) diameter tie rod, 1.3 in. diameter solid forged steel drag link, larger forged, greasable tie rod ends, premium jam nuts and adjuster and it's painted black, so it's ready for install right out of the box! Additionally, you’ll need a modified pitman arm to hook this all up. This kit includes a brand new TJ style pitman arm with the proper taper for the new steering system. Both the tie rod and drag link feature double adjusters so that they do not require removal from the vehicle for adjustment once installed. This unit is designed for use on stock height or lifted vehicles, but for those with big tires, these components are also compatible with ram assist steering. Components are completely bolt-on and kit includes our U-bolt style steering stabilizer shock mounting bracket to allow you to remount a steering stabilizer shock to the new tie rod tube.

Select your lift size in Step 1 — the kit ships with the correct geometry for that height. If you're running a non-standard setup, call us before ordering and we'll confirm compatibility.

Death wobble is a geometry problem, not just worn parts. Cruise Series corrects caster angle and eliminates the flex points that let shimmy start. Replacing one part at a time delays the fix — this replaces the geometry.

Yes, if you've done a lift kit before. Full-day project. Watch the complete JT install walkthrough on our YouTube channel — most owners wrap it in a day. Any off-road shop can run it if you'd rather have it done.

Any non-wear component fails — we replace it. No mileage cap. No maintenance intervals to track. No fine print about voiding if you miss a service. Lifetime means lifetime.

Teraflex's lifetime warranty voids if you miss a maintenance interval. MetalCloak's actual parts warranty is 12 months — their "lifetime" language refers to their service program. No conditions here.

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.

Exceptional customer service. All my questions were asked in a timely manner and parts were replaced when an error occured. I encourage people to make purchases due to their exceptional quality products, but also because of their customer service. Will make additional purchases in the future.

Excellent, strong, and durable products—perfect for both on-road and off-road applications. The customer service is outstanding—friendly, knowledgeable, and extremely helpful with understanding installation and ensuring I got exactly what I needed. I would definitely order again. Top-notch company with high-quality products made right here in the U.S.A.

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!
