The MSD Powersports Launch Master is a universal low RPM limiter. It will provide consistent launches and quicker 60-foot times by setting an rpm limit to stage with. Once the green light comes on, release the clutch and take off - but be sure to hold on! The 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. Easily set an rpm limit to use for the launch. Matching connectors for easy installation. Delivers firm, consistent holeshots. 4-cylinder, coil-on-plug, PN 4350
