If I remember right, cj springs from the front are close (2" wide springs maybe a little longer than your stock ones.)I have a buddy with the calmini lift springs, the first ones were the three leaf lift ones, they lasted until hitting the first rock, the h.d. ones he got from them to replace them were a five pack,so far so good, they ramp a little less than stock ones(I think his was 724 and mine were a 944 with rears up front and stock shocks)but they are ruff riding but could also be his shocks to be fare about it. I would get the h.d. ones you could always take a leaf off.
