Serpent SER401943 38T Solid Axle BB Set X20 Tune  [SER401943]

Fine-Tune X20 Handling with the 38T Solid Axle

For racers aiming to sharpen cornering on the Medius X20 '21 MID 1/10 EP, the Serpent SER401943 Solid Axle BB Set provides a direct, race-oriented option. The 38T solid axle helps reduce unpredictable differential behavior and makes the car easier to place mid corner.

Model Fitment and Recommended Use

This 38T solid axle is made to fit the Medius X20 family, specifically the '21 MID 1/10 EP variants (SER400037 and SER400038). Swapping the diff for the solid axle delivers a more linear power delivery and steadier rotation of the rear end, which many club racers prefer for consistent lap times.

Fitting and Maintenance Advice

Fitting the solid axle BB set is straightforward when the axle is aligned with the rest of the drivetrain. Check bearings and drive cups after installation and inspect the axle after hard sessions to preserve performance.
