Yokomo BD9 Double Joint Universal Replacement Kit B9-010TWA for BD10 series  [B9-010TWA]

Maintenance steps for BD9 double joint

This maintenance kit contains one set of replacement components intended for the BD9 series double joint universal on 1/10 scale RC touring car drivetrains. The parts are supplied to replace worn joint internals and restore a stable drivetrain connection while keeping chassis geometry unchanged.

Intended for builders familiar with basic disassembly, the kit installs into the existing universal assembly. Fitting typically needs only common hand tools and a hex driver used for hub removal.

When incorporated into your setup routine the replacement parts help maintain reliable wheel coupling and reduce play that can undermine cornering predictability. Check and replace the kit after heavy running blocks to sustain handling balance.

This replacement set is designed as a direct service spare for BD9 and BD10 double joint universals, helping preserve drivetrain performance through planned maintenance.
