Serpent X20 BB DJC Ball-bearing Driveshaft Set by Arrowmax AM-010063  [AM-010063]

Sliding ball-bearing DJC for Serpent X20 tuning

The Arrowmax BB DJC set swaps out blade-style driveshafts for a compact ball-bearing sliding assembly designed to fit Serpent X20 drive cups. The bearing unit seats into the cup to minimise free-play, reduce friction and lengthen component life while keeping original drivetrain geometry intact.

This upgrade is intended to refine drivetrain feel and handling. Tuners will notice steadier torque delivery under throttle and fewer binding moments mid-corner, which helps with consistent lap times and easier setup adjustments.

Fitment advice: the BB DJC is meant to slide into existing compatible drive cups. Verify cup compatibility on your Serpent X20 and follow normal disassembly procedures. Regularly inspect and clean the bearing slide area to maintain low friction and reliable operation.

Arrowmax AM-010063 provides a practical drivetrain upgrade for Serpent X20 racers seeking reduced play and smoother acceleration while retaining serviceability and straightforward maintenance.
