Yokomo BD10/BD9 BB DJC Driveshafts by Arrowmax AM-010062  [AM-010062]

Ball-bearing DJC driveshaft upgrade for BD9/BD10

The Arrowmax AM-010062 BB DJC set is an RC-scale driveshaft upgrade designed for Yokomo BD10 and BD9 chassis. The design replaces blade-type, non-bearing driveshafts with a ball-bearing sliding DJC assembly that fits into the existing drive cups. By controlling axial play and lowering contact friction, the assembly helps maintain consistent drivetrain engagement during acceleration and in high-load cornering.

The components are intended for hobby-grade RC tuning and track setup. Installation requires standard driveshaft removal and reassembly procedures for the BD9/BD10 platform, and no additional tools beyond typical hobby workshop items are specified. Use this set when aiming to reduce drivetrain play and stabilize throttle response under race conditions.

This set targets drivers who need tighter drivetrain control on BD9/BD10 cars, offering a maintenance-friendly way to reduce free-play and friction without changing core drivetrain geometry.
