Ok guys, I'm new to this forum and have been doing a lot of searching but have had very little results. I have an 86 k10 truck with 14bolt rear dana 60 front and am currently running 4" lift with 35's. I was wondering if anyone might be running a diy 4" shackle flip with BDS 4" Springs in the rear and BDS 8" springs in the front. I am considering this set up but not sure what size tire to run. I do mostly mud but like the idea of having some decent flex. I dont want to do any fender trimming if possible. Was thinking about running 38's but I may step down to the 36x13.50x16.5 Irocs. As most people know they actually are taller than the Iroc 37x14x16.5. Also If anyone is running this type of set up, I am currious how much money I should expect to tie up in driveshafts. I dont really want to do the front spring swap to longer springs either, I would like to just go with the stock spring locations. Thanks for any input.
