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.

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.

I purchased a set of the Cruiser Series control arms for my Jeep Jk based on postive reviews from different Jeep Facebook pages. Ordered and 2 days later realized they had the very same exact arms on sale in the overstock section. Called them up and they refunded me the savings from my original purchase. Amazing, honest service. Can't wait to get them installed. Keep up the good work guys.

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.

Top notch company. Mechanic lost bolts that clamp upper control arms. Korby sent out spare bolts no charge. Best customer service I’ve come across in a long time. Only suspension brand I’ll ever use.

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.
