Re: Spring Info
David here is what I have found so far and still looking. I am still playing with my 71 Jeepster. The Jeepster front spring is 46" long with a 21/25 offset, standard suspension was 1.75 wide; heavy duty was 2" wide. Rear springs are 56" long with a 23/33 offset & 2-1/2" wide. If you are staying with the stock set up the only alternatives for a lift that I have found so far are custom springs . However stock replacement springs are available from Leon Rosser Jeep, your local spring shop, or Rancho.
I am moving my front springs out board of the frame for a Wagoneer Dana 44. In my case I have a set of 81 J-10/Wagoneer springs to use on the front unless I find something else real soon. They are approximately 47"+ long (I thought they were longer when I got them) with a 22+or-/25 offset and 2-1/2" wide. With the Jeepster and J-10 spring side by side there is between 1" and 1-1/2" difference both in the length and the tiebolt location. Another alternative is to use CJ or YJ springs both are 46" long with a centered (23/23)tie bolt; CJ being 2" wide up front and 2-1/2" wide rear, YJ being 46" long 2-1/2" wide and centered tie bolt front and rear. If you use a CJ or YJ rear spring you will have to fabricate a new rearmost spring mounting point to accomodate the 10" shorter spring. If you use either CJ or YJ springs up front you will have to move both of the front spring hangers forward to keep the axle in the same place up front.
I don't know if I have helped or created more confusion, but either way welcome to the wonderful world of Jeepsters. I am still looking for a spring that is close enough that I can buy aftermarket lift springs without changing the entire setup. Those odd offsets are the problem. I am seriously considering going with a YJ lift kit, since I am relocating the front axle anyway it would only be 2 more spring mounts to make.
