Hardcore Launching
Serious racers know that to get the hardest and most consistent launches you need a transbrake. Even if you have a higher stall torque converter, you'll never get full flash stall off the line by just foot-braking. The LaunchMax for 2011-2017 Mustang is a simple plug-in device that allows you to activate the trans-brake function with a push of the included push button.

All Digital
The JMS LaunchMax has no moving parts, making it extremely fast and durable. Since its all self-contained there are no external relays or other components to fail. It doesn't affect the line pressure or shift logic so that it can be easily used in conjunction with a tune.

Installation
Installation is essentially plug and play. You just plug the LaunchMax unit into the transmission control unit and wire the included activation switch wherever you'd like it. Alternatively you can activate the trans brake function with any switch that provides 12-volt power.

Fits
