    A short fall of the modern day IFS 4wd is the adjustment range provided for successful wheel alignments, this becomes even more of an issue when the vehicle is lifted by more than 1 inch. Not only does the vehicle run into camber and caster issues, but ball joint articulation and clearance issues to the coil over strut at ride and droop height. The new Whiteline offset UCA (Upper Control Arm) is an all-in-one solution for any vehicle that has been lifted between 30mm and 70mm. Providing an increase between +2.5 and +3.5 degrees of caster and up to 1.5 degrees of negative camber increase (figures quoted are based off an approximate 50mm/ 2 inch) along with greater clearance to the coil over strut and more articulation of the arm by virtue of new maintenance free GIIRO bushing technology.

    KCA514 Steering Knuckle Kit - Bump Steer Correction
    Optimizing Steering Geometry for Better Handling and Safety

    The KCA514 Steering Knuckle Kit is designed to improve steering geometry and reduce bump steer. It is completely legal and doesn't require engineering certification or modification plates. This product is VSB 14 approved and ADR compliant. It functions similarly to installing an upper control arm in your vehicle.

    Our engineering team has rigorously tested the aftermarket front knuckle (KCA514) to VSB 14 load standards using FEA analysis, assessing it for a front axle rating of 1650kg. The tests confirm that the product exceeds strength requirements. It is compatible with any GVM upgrade.

    VSB 14 Compliance & Legality

    VSB 14 outlines legal requirements for aftermarket modifications. The KCA514 knuckle is classified as owner-certified, meaning no engineer or certification is needed once installed. This is similar to installing legal modifications such as upper control arms, shocks, or lift kits.

    ADR Compliance & Legal Status

    The Australian Design Rules (ADRs) set national safety, anti-theft, and emissions standards for vehicles. While there are no specific ADRs for steering knuckles (similar to control arms or shocks), the KCA514 steering knuckle meets OE (Original Equipment) design standards. As there are no ADRs governing the "robustness of a vehicle," VSB 14 is the primary standard for in-service modifications.

    Comparison to Other In-Service Modifications

    Other similar in-service bolt-on modifications that don't require engineering or mod plates include:

    1. Leaf Spring Replacement � Parabolic vs. original leaf springs.
    2. Front Strut Swap � OE strut to Formula 4x4 or equivalent.
    3. Bull Bar Installation � No issues with fitting a bull bar.
    4. Control Arm Upgrade � Replacing a steel control arm with an alloy one.

    Whiteline products undergo extensive testing to ensure compliance with relevant engineering standards, offering peace of mind regarding quality.

    Benefits

    • Enhanced Handling: Improved vehicle dynamics, providing better driving confidence and a smoother feel.
    • Better Stability: Improved stability for daily driving, off-roading, and touring.
    • Reduced Steering Correction: No more constant steering adjustments or fighting lane assist features.
    • Less Driver Fatigue: A more relaxed driving experience and reduced risk of accidents.
    • Reduced Tire Wear: Better tire contact with the road, increasing tire life.

    Why the Isuzu D-Max, MU-X & Mazda BT-50 Need This Product

    These vehicles experience chronic bump steer, which leads to significant tire wear. This issue is apparent in both standard-height and lifted versions, but becomes more severe with lift modifications.

    The KCA514 steering knuckle provides a direct replacement, replicating all original features and mounting provisions. Made from hot-forged 4140 AISI steel, it's heat-treated and finished with black e-coat for optimal corrosion resistance.

    Pairing KCA514 steering knuckles with upper control arms resolves premature tire wear, improves alignment, and restores proper handling.

    Can Regular Wheel Alignments Fix the Issue?

    No. While wheel alignments may temporarily reduce tire wear, they don't fix the underlying problem. Alignments are a band-aid solution, not a permanent fix.

    Alternative Fixes to Steering Knuckle

    After extensive testing, we've learned that while an upper control arm may slightly improve bump steer, it doesn't provide a full solution. Adjusting the steering rack pickup point is necessary to properly address bump steer. Using an upper control arm to fix bump steer would cause other issues, such as tire clearance problems.

    The Whiteline steering knuckle is engineered to correct bump steer without introducing new complications.

    What is Bump Steer?

    Bump steer refers to changes in the vehicle's toe as its ride height changes, especially when driving over bumps. This is particularly problematic when towing, carrying heavy loads, or using a suspension lift. Excessive bump steer causes premature tire wear, as demonstrated in real-world field tests and R&D.

    How Does the Whiteline Steering Knuckle Help?

    The Whiteline steering knuckle relocates the tie-rod pickup point to optimize the steering geometry and reduce bump steer across different ride heights. Testing shows a 75% reduction in bump steer when these knuckles are installed in lifted vehicles. When installed in standard-height vehicles, bump steer is reduced to nearly zero.

    Combining the KCA514 knuckles with offset upper control arms can reduce bump steer by an additional 10-15%.

    • 18 x sleeves - 28mm-113mm diameter (5mm increments)
    • 4 x press plates
    • 4 x pulling spindles covering bolt sizes (M10, M12, M14, M16)
      • Rolled thread on spindles
      • Nuts with double washers and encapsulated lubricated ball bearings for strength and longevity (stops nut from binding and stripping thread)
    Ideal for bushings, bearings, spherical joints or other applications. Can be used on workshop press or better yet on car simply and easily. Less force required to remove / install bushings, bearings and joints making use easy even without power tools Benefit Note: Most old and new suspension bushings are pressed in and out with old bearing shells, sockets or just anything you can find. This creates a safety issue, given that heat treated steel will shatter under stress. The assortment of sleeves that make up the Whiteline Press Tool Kit are made from mild steel to allow distortion or crush when over-pressed. These newly designed tools provide an easy way to install and remove Whiteline polyurethane bushings and aid in other workshop pressing requirements.
