RRS Shock Tower Notching Kit
RRS Shock Tower Notching Kit
The Ford Maverick engine bay is just 27 inches across. Early Mustang and Falcon engine bays are not much wider. Ford engine bays did exceed 31.5 inches until the Fox-body Mustang. The RRS coil-over deletes the upper control arm, allowing "notching" of the shock towers. You can make room for bigger motors while retaining full suspension travel and improving your suspension performance only with RRS.
Question
"I want to put 427 dark blocks in my Mad Max coupe but it won't fit. I want to run 17x8 globe Bathurst replica mags and adjust the ride height so the tire sits just right, so I can't use a Mustang2-style front clip. What can I do?"

Answer
The Cammer shock tower notching kit will allow you to fit a big block or a Coyote, the RRS coil-overs will allow height, ride, and camber adjustment.
Gives You up to 10.5” of Engine Bay Space
The RRS notching kit is an optional system that will increase the distance between your shock towers by up to 11 inches, allowing ample space for that mammoth 426 or 429 big block as well as turbo small block and hard-to-fit header applications.
The best part of all is that you retain the integrity (strength) of your shock towers, giving you all the room you need to install that monster Ford V8 in that engine bay. Then, look no further than the combination of the RRS Strut and Brake Kits and the RRS Shock Tower Notching Kit.
The RRS coil-over suspension kits and rack and pinion steering systems are bolt-in and do not require any modification to your classic Ford.
