I don't see how longer eye bolts will help. It would give you less tension. Shorter springs maybe. Are you sure it's installed correctly? When you put that assembly with the plate and folcum(sp)through the A arm frame you leave the nuts loose and slide it towards the front wheel. Then hook the springs onto wheel side then the other side to the eye bolts making sure you have the nut on the back side of the eye bolt threaded on flush. Next slide the bracket in the A frame back as far as you can keeping the folcum centered on the pins and then tighten the A frame assembly bolts. Now thread the nuts on the back side of the eye bolts all the way down stick a screwdriver in the eye bolt to hold back on while doing this.
