XRay X4 ECS BB SC Drive Shaft 58mm - Hudy Spring Steel - Complete Set

The XRay XR305335 X4 ECS BB SC Drive Shaft 58mm – Complete Set delivers a notable step up in drivetrain efficiency. Featuring ECS BB (ball‑bearing) joints, this assembly reduces friction between the driveshaft and outdrive versus traditional blade‑type designs, giving a smoother, more connected handling feel. On high‑speed direction changes, such as chicanes, the lowered friction helps the car maintain momentum and can support higher cornering speeds.

Exclusively manufactured from self‑developed HUDY Spring Steel, the set combines strength and precision for consistent on‑track performance. XRay’s Spring Clip System (SCS) employs a driveshaft case with a C‑clip groove to secure the aluminium pin retainer, eliminating the need for set screws. With pins that float freely in the joints, the assembly rotates smoothly and is engineered for reliability and long service life.
