Rear Quad-Shocks 1989 mustang

The quad shocks are a roll of the dice. No matter what the combination of tires, control arms and shocks, some cars will wheel hop without quad shocks and some won't. There are so many variables in 28-13 year old cars with wear, misalignment and combinations of suspension components and tires that one unchanging answer won't work for everyone.

I personally would install them, and make sure they are in good shape. I do know this, that Ford is cheap. If they could have made changes in some simple component like bushings or control arm construction and saved $10, they would have done it. Multiply $10 times all the Fox body Mustangs ever made and you would be almost as rich as Donald Trump. That's a lot of $$$, and good incentive to engineer something to do away with the quad shocks.

I have the UPR upper and lower control arms along with the 5 way adjustable Illumina shocks and struts and I removed my quads and It didn't affect anything negatively, just my .02

I went out of my way to keep my quads with my Strange adjustable shocks and 275/40/17s....even with my tubular control arms and full length subframe connectors.

It's much better to keep them. The first time out to the track you will rush home to reinstall the quads.

i also say keep them.

i added control arms and etc to my car and i thought i wouldnt need them anymore since people told me that. i ran the car and had HORRIBLE wheel hop. put the quads back on and it went away. they DO work. i'd also buy a new set. you can get them from autozone under "steering damper" i think it was
