- Allows total concentration and improved consistency by enabling you to stage your car with the gas pedal to the floor while the engine remains at near idle. The throttle goes to wide open (up to the launch RPM) when your side of the tree starts, waiting until the "cross-over" times out. This eliminates destructive engine and converter damage due to excessive time at wide open throttle against the transbrake.
K&R is proud to introduce the Pro-Stage starting line control system. This device is a perfect choice for when all you need is a PRO-STAGE starting line controller or a single action throttle stop. Extremely lite-weight to eliminate throttle cable breakage to stay reliable.
Features:
- Universally used as a "PRO-STAGE" starting line controller or as a throttle stop.
- Extremely lite-weight inline throttle control.
- NEW cable saver end eliminates throttle cable breakage.
- Full 2.5-inches of travel (allows full closure of all throttle systems.
