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.

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.

Had a great experience with Core 4x4, I desperately needed a custom track bar and found out just a couple days before Easter Jeep Safari. Spence was a huge help and made it happen with plenty of time to spare. Their parts are top notch!

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.

Great company, who worked with me on shipping parts, to arrive in time for a show, when I explained my concern of possibly not getting the control arms in time. Quality is amazing on the part, affordable price for what you get, and the powdercoat is top notch, not a single issue with this product, would buy again.

Excellent quality product and service. My l lower control arms broke and within the same day core 4x4 hooked me up with tier 2 arms and with the color I wanted. My Jeep rides better and has been solid for several months so far. 10/10 would recommend their products to anyone.

Had a worn out set of rear upper control arms on my TJ. These were old rubicon express long arms. can’t buy replacements and no one makes a direct fit replacement. Talked with Korby at core off road sent some measurements and photos and a week later new arms showed up. Packaging was perfect fit was perfect. Would highly recommend giving these guys a call.
