Yokomo BD10/BD9 BB DJC Driveshaft Tuning Kit - Arrowmax AM-010062  [AM-010062]

Ball-bearing DJC upgrade to reduce driveshaft play on BD9/BD10

The Arrowmax AM-010062 BB DJC set is an RC-scale driveshaft upgrade designed for use with Yokomo BD10 and BD9 chassis. It substitutes non-bearing blade driveshafts with a ball-bearing sliding DJC assembly that integrates into the original drive cups. By controlling axial movement and lowering contact friction, the assembly helps sustain consistent drivetrain engagement during strong acceleration and when cornering under load.

These parts are targeted at hobbyists and racers carrying out drivetrain tuning. Installation requires the usual driveshaft removal and reassembly methods for the BD9/BD10 platform and does not list any special tooling beyond standard hobby workshop items. Fit this kit to trim drivetrain play and steady throttle response in race conditions.

Perfect for drivers after firmer drivetrain feedback on BD9/BD10 models, this set reduces free-play and friction while retaining the existing drivetrain layout and ease of maintenance.
