Serpent Medius X26 43mm DJC BB Driveshaft Set - 402203  [SER402203]

DJC BB 43mm Driveshafts for Medius X26

This 43mm DJC BB driveshaft set from Serpent 402203 is a purpose-made drivetrain component designed for the Serpent Medius X26 steel EP platform (SER400052). The description below focuses on fitment checks, recommended installation practices, and how these driveshafts integrate into a 1/10 electric touring car's drivetrain.

Compatibility and fit: the item title specifies the intended platform, so confirm your chassis is the Medius X26 steel EP with code SER400052 before purchasing. The 43mm length denotes the driveshaft dimension shown in the product listing; test-fit to verify clearance in the gearbox and hub regions. As with all RC replacements, verify spline engagement and rotational clearance rather than assuming interchangeability with other chassis.

Installation and service notes: work on a clean bench, remove necessary suspension arms or hubs to access the driveshaft positions, and inspect hub faces, axle hexes, and mating splines for wear prior to fitting new shafts. Apply thread locker only where the chassis manual directs it, and ensure retaining fasteners seat without binding. After installation, rotate the drivetrain slowly by hand to confirm smooth engagement and that there is no interference with suspension travel or gear mesh.

Tuning role: these driveshafts help restore correct drivetrain geometry and rotational balance on the Medius X26 steel EP chassis. If you experience drivetrain vibration or inconsistent traction feel, replacing or inspecting shafts is a useful troubleshooting step. Always pair shaft replacement with checks of bearings, spur/pinion alignment, and motor mount security for predictable performance.
