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

Refine Your XRAY X4 Handling with 59mm ECS Shafts

For those seeking a steadier balance through long corners, the 59mm ECS BB drive shafts for the XRAY X4 deliver bearing-based operation and Hudy Spring Steel durability. Supplied as a matched pair, they aim to make the car feel more settled when powering out of bends on faster circuits.

What Changes to Expect on Track

The ECS BB design reduces friction at the outdrive versus traditional blade shafts, creating a smoother steering response during abrupt direction changes. The 59mm length is tuned to strengthen steering mid-corner and under throttle, though initial turn-in can be a touch softer than with shorter shafts.

Maintenance Recommendations

Routine maintenance is easy. Fit as you would any ECS driveshaft and use Hudy Joint Grease (106213) between the small bearings and the outdrives to prolong component life and maintain quiet operation.
