The pieces I made were too complicated to make without access to a lathe, but the guy who aligned it for me said that he uses large fender washers under the cast iron block the spring sits on (the one the sway bar ties to). He said he gets them from a bolt supply, and they are 1/4" thick. You can get about 3/4" with the stock bolt before you run out of threads. Any more than that and you would need a longer bolt to hold it all together.
The pieces I made were aluminum, and went between the spring and the sway bar block. The bolt in the center of the spring holds it all together. It is somewhat complicated because it locates the I.D. of the spring. It is a little hard to picture if you have seen the parts, so I will try to get pictures for you.
For the shocks I used Bilstiens which have more travel than stock, and I shimmed them down 1/2" to compesate for the lift.
Hope you are not more confused.
Oh, by the way, I used 1997 F250 U-Bolts on the rear to work with the 1 1/2" blocks I made.
Thanks, I think I got it. I'll look into the washer trick. 3/4 in might just be enough to 'look' right.
I had 1" blocks made for my '00 V10 2wd rear. I had Edelbrock IAS's all around and though I intended to space them down to compensate, I never did. Never seemed to be a problem, though. I had Air Lifts on the back of the V10 also and they are in a box now waiting to be out on the '05 PSD. They seemed to raise the rear a bit even at minimum psi so I'm going to wait to install them before making a decision on the blocks.
