I've lowered several of mine and customers vehicles and have quite a few of extra parts. All prices are plus shipping. Let me know if there's any questions.
McGaughys rear shackle flip. This can either be used to lift your truck 1" or 2" with factory shackles. If they're used with a flip kit you can raise the rear to a 4" or 5" of drop on 99-06 trucks and 5" or 6" of drop on 07+. These are brand new but I don't have the original box. All hardware included. Part # 93049 (I have 2 sets) $75
McGaughys shock relocators for '07-'13 trucks. Brand new never installed. All original mounting hardware included. Part #34044 $50 (I have 3 sets)
