I had a shock leaking so it was buy a new shock or figure something else out. So I called foa about a set of 2.5 reservoir shocks instead of the duals. They said about the perfect valving and with running a single 2.5 it would be perfect on a full size truck. So I orders a set from Dave's Offroad supply, he answered all my questions and was very helpful. They came a week after ordering them, they are really nice. Hopefully they were worth the change. The 2.5 shock hardly fits in the hoop, I wanted it on the front side of the mount but no room for that. Then I had no where to put the reservoir, the hose was either too long or too short. So I made a mount out of tube and bolted it to the frame. I ran out of por15 so I'll order more and paint where bare frame is now showing. I don't like the isolator style resi mounts but for now they will work fine.
