    BMW LSD Spider Gear Cross Pin

    Forged Replacement Cross Pin for BMW ZF Limited Slip Differentials

    Solve one of the most common failures in early BMW ZF plated limited slip differentials with the RacingDiffs forged spider gear cross pin.

    As clutch discs wear out, the LSD slips more than it should, increasing friction between the small spider gears (satellites) and the cross pins. Over time, this leads to cross pin damage or failure. Our forged replacement pin restores strength and reliability to the differential.

    Why Choose RacingDiffs Cross Pin
    • Direct replacement – designed as a perfect replacement for the original OEM pin.
    • Forged construction – stronger and more durable than standard components.
    • Cost-effective repair – repair the LSD without replacing the complete differential unit.
    • Improved reliability – restores strength in one of the most failure-prone parts of BMW ZF LSD units.
