James I saw your coil over thread on DF, do you think 800lbs spring rate is enough? Or would you go more like 1000lbs?. Also thinking about F.O.A shocks.
i have one on DF?? i dont remember putting one there.
there is a lot to consider and spring rate is only one part. you need to figure out where you want ride height, then measure how much suspension travel you want or can live with. being you pull, full suspension compression will something you need to look at as well or where you want the front end to be when full of weights up front (what i mean by this is not how much travel you want left when weighed down, but where you mount the upper shock mount will determind how low the front end will be when full bottomed out). you will also need to find a shock length that will work and more than likely beef up the LCA mount as the weight on the front is really gunna want to break those two little bolts and bend the bracket when you let off at the end of the pull and the front slams down. a bumpstop would be a good idea stoping the shock 1/4"-1/2" from full compression.
i would NOT run FOA. the seals just dont last in them. if you dont mind fixing them, might be a good choice. personally, id find a set of fox, sway-a-way, or kings. a 1000lbs spring might be a bit stiff on the street but may give you a little more adjustment room when weighed down compared to the 800lbs spring. i would start with that spring and go from there. you stuck with a 2.0 shock for any over 800lbs springs though. just make sure you take block height into account when setting everything up. allowing spring bind to happen is a good way to kill a spring in short order.
