XB4 Slipper Eliminator Upgrade for One-Way Slipper Clutch - XRAY 364103  [XR-364103]

XB4 direct on-power slipper eliminator

This RC-scale slipper eliminator set is built for XB4 stock class use when drivers want a firmer drivetrain connection under throttle yet retain one-way behavior off the throttle. The design removes unwanted slipper movement on power to transmit torque directly, while the one-way action off-power still helps reduce front braking effect and improves stability when entering corners or landing jumps.

The components are CNC-machined from Swiss 7075 T6 aluminum and use Hudy Spring Steel outdrives, a combination that balances strength with low rotating mass. Lower rotating mass in the driveline helps improve acceleration and throttle response without altering the vehicle's basic driveline layout.

Tuning role: install this kit when you want crisper on-power acceleration and a steadier off-power balance for technical or high-traction sections. This is an upgrade aimed at changing drivetrain response rather than suspension or chassis geometry.

Compatibility

• XB4 stock class

For competitive XB4 stock class setups that demand a more direct on-power feel while keeping predictable off-power stability, this slipper eliminator provides a focused drivetrain refinement with durable materials suited to track use.
