I have an 2006 F-350 cclb 4x4 6.0l. I want to lower the truck. I plan to remove the rear block and I think the frt needs to drop about 1.5" for the truck to look level without the block. It currently has 6000lb coils up frt. I've tried searching and found 08+ trucks seem to look level with no block and 4800lb springs. Is this true for an 06 also, or will the 4800 springs drop it too much? The other option would be 5200lb springs. Most lowered 05-07 trucks I find have cut coils and I'd rather not do that. Also what is everyone doing for shocks with lowered trucks? thanks
