Going from 4\" to 6\" springs, bushing question Stephen, gonna be ordering 6" springs from you shortly to replace my 4" Tuff Country HD springs. I am using your greasable bushings and hd shackles. Will I probably be able to reuse the bushings, they have been in for about 3 years, but very little actual miles on them. Second question. I just swapped to a BB. As the 6" springs don't come in HD, can I (should I) remove the extra bottom leaf from my 4" HD pack and add it to the 6" pack to compensate for the extra weight of the BB? Thanks and will be calling you in a few days to order.
