Xpress XP-10690 XQ2S XQ1S Mid Pulley Conversion Kit

Performance upgrade kit for the Xpress Execute XQ2S and XQ1S, the pulley has been moved to the middle of the drivetrain. With equal length belts for both the front and rear, this results in almost equal power delivery to both ends of the car allowing for earlier throttle exiting the corner.

By moving the pulley, the motor has been moved forwards as well putting more weight forwards and changing the weight balance by shifting one of the most heavy objects on the car.
