Designed and developed alongside Ford Racing for the 2014 Factory Built drag race program! For the serious Mustang drag racer, the Watson Racing wheelie bar is designed to work with 9-inch rear axles only. The kit includes brackets that have to be welded to your axle housing, as well as a small sheet metal notch that must be welded into the spare tire well, for wheelie bar clearance. Will work with any 2005-2014 Mustang -possibly other years as well- using a 9-inch rear axle. Constructed of CNC mandrel bent 4130 chromoly tubing, precision TIG welded in fixtures, and powder coated, all right here in Michigan. The Watson Wheelie Bar is a product of months of extensive testing and dozens upon dozens of passes down the track- no shortcuts taken here. Contact us if you’d like us to weld the brackets to your axle housing.
