4Crawler Offroad Products - Front Differential and Sway Bar Drop Kits
i run all of his brackets and drops. Top tier.
Bj spacers, Diff, sway, pan hard and the brake sensor or whatever its called.
Cvs have no bind at full droop, they bound enough when I installed my bj spacers where I could barely rotate the front tires by hand when it was jacked up and hubs engaged(2wd on the selector). Soon as I put the diff drop in, smooth as butter on the rotation on stands with hubs locked
Edit: you might want to do some research on the 4in lift, as I am only at 2 with my tbars and ome 900s and spacers. A 1 in drop that 4crawler offers will definitely help, but a 4 in lift is quite a height. You can relax your tbars a bit to help those cv angles as well. It will improve the front end ride quality
