heres my opinion on the "suspension vs. body" debate...
My old truck - 2001 EDGE 2wd w/ body lift, 4.56's, and 32's.
It handled the small stuff well and street driving was fine. Kind of a harsh ride, though. Some of the bigger stuff this truck didn't like... like the Barstow and Pismo trips I came along to... (Alon, Trent - you know what I'm talking about)
My new truck - 2000 XLT 2wd w/ Camburg 5.5, Deaver LTs, and 33's.
Handles pretty much everything I want to do... taking on whoops and jumps at a pretty good speed. Handles great on the street, too.
The spindle package is your best bet. Putting on those body lifts don't give you anything but tire clearence and an ugly frame to look at. Spending the little extra to get the spindles would definately be your best bet. You don't get an ugly frame to look at and it performs much better than would a body lift. Plus it makes it have a wider stance up front. Now, I know that my Camburg kit isn't exactly just a spindle - its much more than that, but it looks somewhat similar. The spindles would perform much better than a body lift, but wouldn't outdo the Camburg kit. Sorry if this post is a little much, I should have listened to people here on the forums before I put the body lift on my old truck.
