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.
