How do I work out the height I will need and the spring rate.
They range from 14" to 18" in height.
Dobinson Springs can make them for me.
It is not on the road and will only be trailered.
Any help will be great...
There are a lot of things to consider when doing a coil conversion, have you got the linkage design sorted?
IMO you should start with 175lb springs and go from there.
