Shift Cut Gear Knobs

Holinger Gearboxes work exceptionally well with clutchless upshifts, particularly when used in conjunction with a shift-cut. A "shift-cut" momentarily interrupts the torque output of the engine, allowing the driver to rapidly change gear while maintaining wide-open throttle. Holinger has developed a range of Shift Cut Gear Knobs that are installed directly onto the gear lever. It sends a signal to the Engine ECU during gear changes which can be programmed to interrupt the engine torque output.

H-pattern Shift: This allows the gear lever to be pushed or pulled in any direction, providing a trigger signal to the ECU. The ECU filters the signals to only cut torque during upshifts.
