trying to get some info from possibly someone who has or have done some upgrades in the past. GMC is an odd duck compared to Chevrolet as it has coils up front, and leafs in the rear. So my question is, is there a company that offers a lowering kit? Or will Chev coils fit on the front? And what would be best on the rear? We would like to go as low as possible, we dont want to go thru all the fab work of bagging it so it will be a static drop. possibly thought about moving the spring mounting perch's up higher on the frame rails. keep in mind this is sort of a budget build, but if we gotta do a 4 link and coil overs to achieve the proper drop well then so be it. But would like to see and hear what others may have done. Thanks for taking the time to read and hopefully offer a little insight..
