Put a 4" drop and have pretty good vibrations at mainly hwy but 45+ a little also. Do ya'll think a 2* shim should fix me?:confused:

Shouldn't it be towards the front, I didn't use a flip kit.

URGENT
Hey 97 look I got the leafs up finnaly but looks like when I go under them the bolt head on the bottom that fits into the whole on the top of the mount that is on the rear end won't be long enough to go all the way thru shim and mount is that a prob. Let me know soon as you can

Let me know soon as you can I thought the same thing when I first looked at mine but it turned out alright. I know when I ordered my shims (Belltech) they came with new bolts. Unless something is different on the new body style trucks I wouldn't think you should have a problem.

I just went up to 4 wheel parts here in town. They didn't give new bolts but I finished just now. I actually had to put mine forwards because the yolk was aimed up. To put the shims in the back would have aimed it further up. That job wasn't all that fun no new ponies. Thanks again:rocking:

I would think it should be pointing down. Oh well, as long as it works!! Have you test driven it yet?
