I had a TG front 3link on my old truck. It flexed great and the geometry was fine, but the cog was very low, i think 22" to the bottom of the frame, with 39's. You can run it with hydro assist, but it would be tough, there is just not alot of room for your pandhard, brackets, pitman, and drag. The brackets to your lower links, sit right behind your t-case crossmember, so if you want to push your axle farther forward you would have to cut some of the skid plate up. They are also 42"s long I think, and sit just below your frame, so they could get caught up easy if your not paying attention. I don't know what valving trail-gear gets from fox, but if you dont want to spend alot of time tuning them, make sure you tell TG your trucks specs and send you a good guess of what valving you would like. Mine were way to soft. In saying all that, its cheap, easy to install, and I thought worked great. Cheaper than putting your own together and there is no guess work in the geometry.
