Hey guys, well I've owned a 2007 silverado 1500 classic 4wd ccsb with a 12" full throttle suspension lift. Recently had EFI live tuning, 5:13 gears installed, and a fully built trans installed with billet everutjing, extra clutch packs, and bigger torque converter. I'm getting a lot of axle wrap and axle movement. If I lay into it once I hit second gear people behind me are saying my axle cocks forward about 25 degrees until I hit another gear my truck clunks and then the axle shifts back to normal. Everything seems normal and is torqued to spec underneath the truck with the rear suspension. Will ladder bars fox this problem or is sometjing else wrong? I have 12" lift springs in the rear with a factory block. Any and all help or advice would be greatly appreciated! Thank you!
