Hey Kids.... anyone out there added an additional crossmember for frame strength ? I just put my sliders on this past sunday, and when putting weight on them I can actually watch the frame tweak. They weld straight to the the frame. Am planning on building a crossmember for just behind transfer case to tie things together. Looking for ideas before i start building. 1990 K5 4" lift, 33" MTR's, 14FF w/ Detroit locker, D44 w/ posi, 4.10's Raptor Tranny and Velvet Rides !
