MSD RPM Two Step Module Selector 2011 Ford 5.0L Modified Motor 2010057 and other poly-lock style rockerThis 2 Step connects right to your late model Ford to produce consistent launches and quicker 60 foot times by setting an rpm limit to stage with. When activated, the rpm will be held at a steady rpm and 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. MSD
