This ground shaft is used to checking the lower a arm bushings for alignment along with the squareness of the lower a arm chassis points. If everything is correct you will be able to slide the shaft though the chassis holes and the bushings in the lower a arms. Includes 2 shafts and works very well with our Set Up Plates, Caster Camber and Plumb Bob kits to find your true wheel placement in your race car.

                LOWER A-ARM AND CHASSIS MOUNT CHECKERSeems like a simple rod, but don't fool yourself. These checker rods are precision machined. Don't settle for just good enough, get these rods and you will know your mounts are perfect!

                Great toolGreat tool to find out how bad out of whack control arm mounts are from the factory. Great for checking used control arms for binding.
