I was wondering if anybody has used springs from a chevy truck newer than 99 for a swap onto a 1st gen 4runner. And if there was any reason anybody hasn't? I have access to some really nice 63" springs from a 2006 silverado RWD.

According to this chart, the only real difference, aside from pack thickness, is in the 1,425lb springs. The newer springs are only 2/1 whereas the older packs are 3/1, which could make it a little harder to fine tune your spring pack. I'd say give it a shot and let us know how it works.
