CORE 4X4 Complete WJ Knuckle Swap Kit – Compatible with Jeep Cherokee XJ (1986-2001) (J-XJ-WJKSK1)

The Ultimate Steering Braking Upgrade for Your XJ

Transform the front-end performance of your Jeep Cherokee XJ (1986-2001) with the CORE 4X4 Complete WJ Knuckle Swap Kit—a comprehensive solution for upgrading steering geometry, braking power, and overall handling. This kit includes everything needed to swap in stronger WJ knuckles, a 7075 aluminum high-clearance steering setup, and larger rotors and calipers for improved stopping power. Whether you're running bigger tires, tackling technical off-road terrain, or simply looking to modernize your XJ’s steering and braking, this kit is the ultimate solution.

Important Installation Note: Cutting and welding required. Some hub modification may be necessary.

Key Features and Benefits

  • 7075 Aluminum HD Steering – Tie rod and drag link are built from aircraft-grade 7075 aluminum, offering extreme strength while remaining lightweight.
  • Over-the-Knuckle (High Steer) Option – Raises steering linkage to improve clearance and minimize tie rod exposure to off-road obstacles.
  • WJ Knuckles for Superior Steering Geometry – Upgrading to WJ knuckles eliminates weak stock XJ steering, improving turn radius, bump steer resistance, and overall durability.
  • Bigger Rotors Calipers – The included Explorer Sport Trac rotors and WJ brake calipers provide significantly improved braking force, making them ideal for XJs running larger tires.
  • Better Heat Dissipation – The larger rotor size reduces brake fade under heavy loads or steep descents.

Built for Strength and Performance

Designed to handle the toughest conditions, this kit upgrades your XJ’s weak factory steering and braking components with a complete high-clearance system. The 7075 aluminum tie rod and drag link provide extreme strength while keeping weight low, and the larger brakes ensure improved stopping power, making this kit essential for lifted vehicles and extreme off-road applications.

Fully Engineered for a Complete Swap

This is a true bolt-on solution that includes everything needed to install WJ knuckles, high-clearance steering, and upgraded brakes. The raised axle-side track bar bracket corrects steering geometry, ensuring proper alignment with high-steer setups.

Optional Add-Ons for a Fully Customizable Build

  • Over-the-Knuckle (High Steer) Setup – Converts the steering linkage to a higher mounting position, reducing tie rod exposure to rocks and obstacles.
  • Sway Bar Relocation Tabs – Needed for proper sway bar mounting when using the High Steer setup.
  • New XJ Hubs (Modified for WJ Swap) – We offer machined hubs for a direct-fit install. If reusing stock hubs, minor grinding may be required.

Installation Considerations

This kit is a cutting-edge upgrade but requires cutting and welding for installation. For the best results, we recommend professional installation or advanced mechanical experience.

Two-Stage Powder Coating for Maximum Durability

To ensure long-lasting protection, all steering components undergo a two-stage powder coating process.

Zinc Primer Base Coat – Provides superior rust resistance.

Durable Top Coat – Available in 10 custom colors to match or contrast your Jeep’s suspension while adding extra durability.

Installed rear and upper control arms and track bar on my 3rd Gen 4RUNNER to align rear axle and restore factory wheel base after 3.5" lift. Car drives better than New! Improved handling cornering and overall driving. Very solid and high quality made product. Support is outstanding. Shipping extremely fast. Thank you so much. I wish you will have something new for my car.

I purchased upper and lower adjustable arms for my WJ and lowers were missing the spacers. I didn't know until 3 months later when I was installing them. With absolutely zero hassles they quickly sent me the missing spacers. Fantastic product and service! Huge thank you guys for the awesome service and parts!!! Customer service is quickly becoming a lost commodity and you guys gave me hope that it's still alive and well, you just have to buy from the right people... Thanks again for going above and beyond! 👍👍

Have full upper/lower CA set on both front and rear axles on a 96 ZJ. These are the rubber bushing sets not joint sets. I have beat the hell out it in the Nevada desert for 2 years and has been great. I don’t go fast but I do articulate suspension a lot. Super solid and haven’t any issues. Just inspected the entire set recently due to some banging under it. Turns out the banging is lower rear shock bushings. Inspected each CA along the way nothing. Aside from dirt and obviously winter roads and what not still in excellent condition, bushings are solid like the day they were installed. I’ll add that I’m about tapped on a short arm at 4.25(less with settle) so the front CA’s get beat on just from that, still they’re like new. Paint is great condition, this set is red. I would definitely buy again. Another plus for me, Utah isn’t local necessarily, but it’s nice to support businesses closer to me.

Great product, excellent customer service. I mistakingly ordered a track bar for the wrong year model and Korby helped me out by sending me the correct part that I needed no questions asked. I highly recommend.

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.

I met a couple of the Core 4x4 guys at the Salt Lake Offroad Expo and decided to try them out after noticing one of my control arm bushings was disintegrated. I called to discuss parts on Thursday and I was leaving for a trip on Saturday. These guys built my control arms and had them ready to be picked up Friday, 24 hours later. The parts seem to be great quality and they charged me nothing extra to have them painted. These guys were extremely helpful and without them my trip probably would have been cancelled. looking forward to testing out the arms on my next trip to Moab.

Small business, family owned, made in the USA, lifetime warranty. Purchased Tier 3 control arms and rear track bar for a 2006 Jeep LJ. Simple website and easy to contact over phone and email. I had some technical questions and they were happy to answer them. They allow local pickup and were built to order same week. The order was wrapped and ready when I walked in and even gave a tour of the shop. They abrasive blast all raw materials to achieve a better surface profile for powdercoat to adhere and create a smooth, durable finish. I also noticed several CNC machines and a robotic welder they use for all their parts. A small outfit with a robotic welder? Their concern for quality is obvious and it shows in the parts they make. Very impressed. Happy to do business with these guys.
