Our Sales Experts take calls all the time from enthusiasts that want to eliminate wheel hop while also staying on a
tight budget. This is where the Stop the Hop Starter Kit comes in. Our team of engineers got together and came up
with the best 3 parts for eliminating unwanted wheel hop in the new S550 Mustang. A kit that gives you the
fundamental foundation for ultimate traction and suspension compliance. As we have explained before, the factory IRS
subframe, (often inaccurately referred to as a cradle), mounts to the S550 chassis with 4 mounting locations
utilizing 4 soft rubber bushings with plenty of voids, even in the bolt holes. The kit we put together addresses
these issues and more.
Which "Stop the Hop" Kit is for you?
First is our Alignment dowel kit. This fills the factory bolt hole voids with CNC machined delrin inserts that will
square up the rear subframe to the chassis. By filling these voids we are also limiting the side to side and front
to back movement of the subframe that is present under hard acceleration and braking.
Second is our tried
and true IRS Subframe Bushing Support System. This 8 piece kit was a first of it's kind in the performance
aftermarket and so innovative and popular we patented it's design! Made in house from billet 6061 aluminum and
featuring stainless steel hardware, this kit fills all the factory voids in the IRS subframe mounting locations.
It's job is to prevent up and down movements of the subframe.
The 3rd and final piece to this kit is the
strongest support brace for the S550 IRS on the market!! Made in house from chrome moly steel, this brace is
designed to support the factory subframe by directly tying it into the chassis at key mounting locations. Using
factory mounting locations on the factory frame, this 5 point brace supports the front factory mount and the lower
control arm mount as well. A simple bolt in design this brace ties the subframe to the chassis in the best possible
The best part about this kit, is the price. These 3 parts were the first of their kind for the S550
Mustang and nothing will prevent unwanted subframe movement or wheel hop better than this kit.
