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.

Made in the USA

CORE 4X4 manufactures all steering components at our Orem, UT facility, ensuring strict quality control, premium American-sourced materials, and expert craftsmanship. By choosing CORE 4X4, you’re investing in durability, innovation, and long-term reliability.

Recieved warrenty exchanges for my control arms last night couldnt be happier!!! Lets talk about the arms tho! Great quality arms in multiple styles and colors!!! I purchased the teir 3 short arns for my 98 xj. I can say that they setoff nicely so my 35 inch tires do not rub! As long as you can get a photo or video of broken hardware core will take care of you. The body of the arm is bulletproof. However make sure to maintain and grease the joints regularly as with any greaseable joint and they shouldkast forever. I had a few problems arise a year after purchase and after some troubleshooting spence was able to help get me the correct parts to get back on the road. I recommend this setup to any and all jeepers looking to get away from the stock arm setup. Alltogether i am Very happy with the performace of my control arms!!!! Mechanic and bodyman of 12 years and my first choice for quality control arms!!

Excellent service, Prompt responses when needing technical assistance, Amazing looking parts that fit excellently. I would recommend them to anyone looking for suspension components. Also very well packaged when we received the shipment, which means no damage from shipping company!! We went with the Crawl Series double adjustable kit and it definitely looks killer on our build!!!

I ordered the jeep xj long arm lift kit. Control arms showed up first they turned out amazing!! Had some issues with the powder coating on the cross member and sent korby and the team at core4x4 an email. They got right on making me another cross member and sending it out. I appreciate all the help they've given me along the way. Very fast response thru emails. Build quality seems to be pretty dang nice!! Can't wait to install it and enjoy it!

Core 4x4 has outstanding products at a fair price and unmatched customer service. When you call Korby, it's like talking with a friend. Very cool and helpul! I ordered some custom control arms, but from the wrong product line and they were super cool about returning them and upgrading to a better "Crawl" series. Only charged the difference between the two products. They paid all the return shipping and sent the uprgaded arms super quick. It was only a couple days. Awesome!! I couldn't be happier with the transaction👍🏼 Also, these control arms are stout and take a beating. I run heck out my Jeep in the rocks and desert. No problems whatsoever. Thanks Core 4x4, ya'll are welcome at my campfire anytime! Jake T. Pleasant Hill, Or.

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.
