    The 7075 X3 Capped Billet Front Knuckle Set is a race-ready option in a lightweight package. With larger, more consistent cross sections and no stress risers, this kit offers improved durability and performance.

    Just like our race saving rear knuckle the ZRP Desert Series Front Knuckle has been designed to handle the harshest conditions and most aggressive drivers, allowing your X3 to make it through even the most challenging of conditions. 

    Additionally, we have addressed the wheel bearing issue. Taking over 50,000lbs of force the ZRP knuckle is 3X as strong as the stock knuckle.


    We eliminated stress risers and added cross section in all the right spots to make this part truly race worthy. 

    Made from high quality, USA made, 7075 Aluminum. Limited Quantities will be available. Call for exact lead time.



    • Uses a steel alloy threaded cap to secure the wheel bearing. No more flimsy circlip.

    • Stronger tie rod mounting points. Boxed and reinforced to prevent failure.

    • Stock geometry, simply bolt on in place of your factory knuckles.

    • Recommended with wheel bearings. Includes upgraded ARP bolt on the lower A-Arm ball joint.
