Enjoy years of trouble-free automatic shifting by mounting one of these Biondo Electric Solenoid Shifter Kit behind your existing shifter. They will improve the consistency of your race car and allow you to focus on winning instead of your tachometer. Each unit is permanently lubricated, and no air bottles are needed. A lightweight mounting bracket aligns the solenoid behind any forward pattern shifter. For reverse pattern shifters, a swing-away bracket is required.
How it works: Pull your shifter into low gear, and the solenoid automatically cocks. It stays that way until your engine reaches the RPM set with an RPM activator switch. Power is then cut & the spring action shifts into high gear. Unlike other shifters, when that RPM is reached again, the unit won't shift more than once.
