5.0 Resto Quad Shock Bracket Kit


Alright, so I know the old-school Fox Body folks are probably thinking, “man, I threw a lot of quad shocks and brackets in the dumpster back in the day,” A few of us probably still do it.

Well, I think we all know how this works. As the cars get older, the good ones get more difficult to find; they change ownership, and so on; a lot of us want those factory-style parts, which is exactly why we wanted to offer a replacement factory-style quad shock bracket. The 5.0 Resto quad shock brackets feature steel construction and a welded 10.9 bolt to serve as the stud. They feature OEM dimensions and tolerances, so the fit and finish are exceptional. They’re coated in a black corrosion-resistant coating, and the mounting holes are precisely located in each bracket. Kit components will include two side-specific quad shock brackets and new retaining hardware for a complete installation.

As far as applications are concerned, these quad shock brackets will only work with 1984 to 1993 cars originally equipped with a V8, as well as 1984 to 1986 SVOs.

    Restore your 1984-1993 Fox Body Mustang's rear suspension performance with this 5.0 Resto rear quad shock bracket and hardware kit. The rear quad shocks are installed to reduce the axle wind-up that causes wheel hop. They did this by damping out the axle's tendency to rotate during acceleration. Often, these are removed when installing aftermarket lower control arms or for added wheel clearance. These brackets bolt to the rear frame rails and supply a mounting point for the rear quad shock that is attached to the rear axle. Whether you are replacing rusted-out brackets or reinstalling missing quad shocks during your restoration, 5.0 Resto's quad shock and hardware kit is the perfect solution for your next Fox Body Mustang suspension restoration project.
