MSD- Mod-Motor 2 Step Launch Controller

These MSD Launch Masters connect right to your late model Ford to produce consistent launches and quicker 60 ft. times by setting an rpm limit to stage with. When the MSD Launch Masters are activated, the rpm will be held steady. Once the green light comes on, release the clutch and take off, but be sure to hold on! The Launch Masters' rpm is adjusted with two built-in rotary dials ranging from 1,800-9,900 rpm in 100-rpm increments. A handy LED shows when the launch rev limit is active.
