    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.

    Suburbans have a 1" x 3" channel for the carrier bearing when they have a 2 piece driveshaft. just ties the top of the frame together. Although you have flex coming from the bottom part I take it? Your driveline would be your only limitation.

    The rear mounting plates for my sliders extends below the frame 2'' . I welded a piece of 2'' square tubing across the frame between the plates. I gusseted the mounting plate on the outside of the frame up to the sliders. This took care of any flex even with the entire weight of the truck resting on the sliders on the waterfall at Disney, OK

    Your crossmember sounds stock. The factory used them to mount up the skid plate. It's just another tranny mount thrown in.

    Sure,..... i'd like to see some pics of it..... I may give me some better ideas. Right now my plan is a piece of 2x4 (box steel) with gusseted ends and plates that run up the sides of the frame and it will bolt on.
