Sun Tool Co.'s Speed Pro-brand F-150 adapter system is designed to allow technicians to setup and successfully machine rotors on 2004 and newer Ford F-150 two-wheel-drive six- or seven-lug vehicles with internal bearings. The company says its patented No. 609350 adapter doesn't require removing the bearings, allowing technicians to machine the rotors, instead of replacing them, saving time, and the customers' money.
