This is the same upper shock cross bar setup that comes with our mini-tub kits. It includes everything you need to mount coilover shocks in the rear of your 1979-2004 Mustang. This set up allows you to hang coil over shocks in-board of your factory mounts with ease! It slides up between your frame rails and gets welded in to place. Constructed out of 1-5/8â€³ x .083 Chromoly tubing. Proudly made in Michigan. Bar, brackets & hardware included.
