    Vehicle Fitment / Finish

    FEA TESTED

    Strength tested and meticulously designed to protect against weak spots

    LONG LASTING

    Completely sealed uniball extends its lifespan and provides overall improvement

    DURABLE ANODIZING

    Finished in type II anodizing for a strong, durable coating

    PRODUCT HIGHLIGHTS

    AMERICAN MADE

    CNC precision machined and anodized in California.

    COMPLETELY SEALED UNIBALL

    Only our billet UCA has a completely sealed uniball, extending the lifespan of the fastest-wearing component. By keeping the Kevlar-reinforced PTFE liner free from debris and grime, we help ensure it lasts longer.

    CAD DESIGNED & FEA ANALYZED

    Using 3D scan data, we reverse engineer the geometry and optimize it for lift. This optimized geometry creates balanced comfort and performance both on and off road. Several prototypes are made, fitted, and analyzed to ensure correction of camber, caster, reduce bump steer.

    MACHINING DETAILS

    Large chamfers at inside radius increases clearance for the coil spring at full suspension droop.
