7. With Summit Racing being the one-stop shopping outlet that it is, we ordered up one of Flaming River’s Big Switch and Lever kits (PN FLA-FR1003-2). Flaming River offers a number of different battery switches, and its Big Switch and Lever fits the requirements for IHRA/NHRA competition use. With mounting the switch, again, you’ll likely spend more time planning out its location than actually installing it. Things to consider are its proximity to the battery, and where you want to drill the hole for the threaded aluminum rod to poke through.
