Hay guys!!!! got the add a leafs in saturday night. Tuff country's added about 3 inches to the rears. It will settle I'm sure. The ride is the same and the install wasn't to bad. New U-bolts and a cetaline torch to heat up the bands on the leaf springs plus a grinder for the center bolt is all you need. I would say 3-4 hours now I know how to do. Looks good. The 35 x 12.5 x 16.5 don't rub lock to lock. It was 35 here and windy so the girl friend didn't want to pose. Give me a week. I'll get athe truck and her for my picture. Thanks again guys!!!!!!!!
