If your Coyote powered Ford was built after February 23, 2016, and you need a 2-Step rev-limiter for consistent burnouts or launches, MSD part number 87311 has you covered.

• When activated, the 2-Step will hold your engine at a constant RPM. This can be achieved by way of a clutch switch or push button. As soon as your activation switch or button is released, full ignition is restored and you're off to the races.
• The rpm is adjusted with two built-in rotary dials ranging from 1,000-10,900 rpm in 100 rpm increments. A handy LED shows when the launch rev limit is active.
• Connects to the factory coils for easy installation
• Easily plugs into factory coil connectors
• The best way to achieve consistent launches
• Easily set a launch rpm for consistent holeshots
