Energy Suspension makes a product called hyper flex bushing system, which replaces ALL suspension and chassis bushing from front to back on 87-93 foxes. The kit runs about $200. I am having some problems with wheel hop and spinning the tires, but I do have quality aftermarket upper/lower control arms, springs, shocks and struts. I do not have frame ties and I use street radials. I was wondering if anyone had an opinion on how much the bushing kit could help my problem.
