Scott Drake now offers their own brand of new steering boxes. These boxes feature a quick 16:1 ratio for a very responsive and precise steering system and improved needle bearing design for smoother operation. The direct bolt-on design requires no modifications or core charge. The 16:1 ratio is the same ratio used on all high-performance mustangs (GT, "K" car, Shelby, Mach 1, and Boss models). Power steering cars also feature the 16:1 ratio. Most of these boxes are worn out after 45+ years of service and are not rebuildable. Scott Drake's new boxes eliminate play in the steering wheel, steering hesitation, and wandering. It improves high-speed tracking and an overall sense of control. This is also an excellent upgrade for regular production Mustangs with manual steering and slower 20:1 ratio.
