I am new to this site. I just bought a 1ton GMC. I have several questions. 1.Will I have to lengthen the drive shafts with a 6" lift? 2.Any other drive line mods? 3.What will longer front shackles do for me? 4.What front springs would you use if going to a Cummins? 5.Will a rear shackle flip decreas the load capacity of my 1Ton. 6.Who has the best stainless steal brake lines? 7.Thoughts on doing rear disks on the 14boltFF? 8.Does anyone have experience with the swamper truxxus mt? 9.I think I'll stop here. For now.
