The Arrowmax BB DJC set upgrades blade-style driveshafts with a ball-bearing sliding assembly made to suit Serpent X20 models. The bearing section seats into the drive cups to reduce backlash, cut friction and extend service life while keeping the original drivetrain layout unchanged.
This upgrade is intended to sharpen drivetrain response and handling predictability. Users will notice steadier torque flow under acceleration and fewer binding episodes in corners, aiding setup work focused on grip and balance.
Installation guidance: the BB DJC is designed to slide into compatible drive cups, so verify fitment on your Serpent X20 before fitting. Routine maintenance should include cleaning the sliding bearing face and checking for wear to sustain low friction and longevity.
The Arrowmax AM-010063 BB DJC set is a subtle yet effective drivetrain upgrade for Serpent X20 cars, focused on reducing play and friction to improve acceleration and cornering stability while remaining easy to service.
