XRAY 305317 X4 ECS Bb Drive Shaft 59mm Hudy Spring Steel (2) Circuit Tuned Shafts  [XR-305317]

Enhance XRAY X4 Response with 59mm ECS Shafts

Drivers wanting crisper handling on fast circuits can fit the 59mm ECS BB drive shafts to the XRAY X4. Built from Hudy Spring Steel and supplied as a two-piece set, they aim to lower drivetrain drag and stabilise steering through sustained turns.

Benefits of the Bearing-Type Driveshaft

Compared with blade-style driveshafts, the ECS BB configuration reduces contact friction between the shaft and outdrive. You will notice smoother reactions when changing direction quickly, and stronger steering influence through the middle and exit of corners. Initial steering bite can be slightly reduced relative to shorter shafts.

Simple Upkeep for Long Service Life

Upkeep is easy: assemble following standard ECS procedures and add Hudy Joint Grease (106213) between the small bearings and the outdrives. Regular greasing and checks will help prevent accelerated wear.
