The XRAY 364113 - Narrow 3-Pad Slipper Clutch Shaft is designed to improve XB4 drivetrain efficiency. Manufactured from Hudy Spring Steel, the shaft offers strong fatigue resistance and durable service life. The narrow 3-pad layout reduces rotating mass for better on-throttle behaviour and more precise handling.
Hudy Spring Steel is selected for parts that must resist repeated stress. Heat-treated for increased hardness and finished in black to reduce surface wear, the shaft stands up well to regular track use and competitive demands.
Reducing the cross section of the shaft lowers inertia, helping the model accelerate faster and react more quickly to driver inputs. This makes the car feel livelier off the line and more agile through technical sections.
A practical upgrade for XB4 owners who want improved throttle response and robust component life without complex changes to their setup.
