Procomp Electronics Thunder Starters
Start your engines with Procomp Electronics Thunder starters—they deliver maximum cranking power! Thunder starters are designed to fire up the highest compression engines under cold or hot weather conditions—and feature all-new components, beginning with a 3.0 hp motor. This power is used to crank over the reduced 4.4:1 gear set, delivering great torque to the ring gear to get the engine turning. In addition, Thunder starters feature high-voltage tested armature and field coils for reliable performance. These units are available for a range of applications, including Chevy small and big block engines, the Ford Windsor, Cleveland, and GM LS1, LS2, LS6, and LS7 engines.
