I spoke with a rep from Wheeler's yesterday in regard to leveling my 08 Urban Runner while leaving the rear at stock height. He actually called me to confirm that I wanted the top out 1.25" spacer, instead of the preload 1.25" spacer. I asked him about a specific DS kit number during our conversation, and he stated that he couldn't confirm a DS number because they order in bulk. The point being, at this juncture, Wheeler's has either type spacer you want to buy. They apparently buy components and assemble their own kits.
I wish I had noted the gentleman's name who called me, because he was very eager to please and deserves recognition. He actually called me back a second time to clear up a statement that I had made in the previous conversation. I was under the impression, based on reading J.A.'s excellent install guide, that the springs need not be compressed when solely installing a top out spacer. He told me that I will indeed need to compress the springs in order to replace the top studs. That makes sense, but it sure does sound as if it adds significantly to the task at hand. Is there no chance of the three existing top studs being long enough to accommodate a 1.25" top spacer?
