I have a set of rear Fox 2.5 Performance series shocks for sale with about 7,000 miles on them for anyone interested. Also Fox 2.0 Ford Performance coil over with about 20,000 miles.
I added the ICON leaf pack. Great addition to ride quality. Also quality at ICON seems top notch. I had Deavers on my ZR2. Rusted and squeaked terribly after 1 NE winter. ICON quality seems much better.
Because I started off with the Ford Performance Fox 2.0 (front and rear) installed by Ford and still had stiff ride in the rear. The front had to be aligned 3 times to get it right the first time. And the front Fox 2.0 are $2,000 not installed.
