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.
