Guy's hate to bother ya'll with this I know it's been touched on a million times but I just bought a 07 NNBS ext Cab thats been lowered,the truck was a repo and bought at a sell in texas,I've got a NBS thats lowered 6 and 3 but not sure on the new truck,all I can tell is that the shackle or the mount for it has been replaced and rewelded the bump stops have been removed and the blocks are gone.The front I have no idea on,all I no is that the upper control arms had to be replaced at the dealer before I bought the truck, they were wore slam out,alright with all that said I'm thinking maybe 3 and 5 or 3 and 6anyone fimilar with a kit like this,i would like to be lowered about 7in's in the back,could I add on to this kit or just start over,one last thing the truck is a Texas edition it has cloth buckets with a console and a towing pacakage is that all the texas edition means.Oh i'll try to get some pics as soon as the rain stops.THANKS A LOT!
