Good day to work on the Jeep

bro-dozer motorsports, i like that.

(sticker on the truck behind you)

Trusses usually go on the top of the axle not the bottom, you just killed your ground clearance, and I wouldn't expect that thing to stay on there very long if you do any serious wheeling. And where did all that rust come from if your in Cali?

Trusses work better on the bottom of the axle, and if your just doing desert wheeling, it's fine. If I were you, I'd run some plate (with speed holes would be better) between the truss tube and the axletube, since the truss tube alone isn't doing much to prevent the axletubes from bending. Looks good so far though. Gotta like the XJ's.

Yea I plan on plating in the truss. It was just late and I was tired. I don't rock crawl, I am more into the high speed desert stuff now.

I hate to tell you, but those welds are gonna last about a week of on road driving before they crack. You can't weld mild steel to cast with bare wire, at a minimum you need flux core wire or 10018-d2 rod. Idealy you will want to use nickle rod. Just thought I would let you know, it will be realy easy to crack also because of the weld bead not being 100%

my dads axle is trussed with the same welder and same tubing and same settings and its been there for 3 years. no cracks

If your running down the desert and hit a jump and land which way will the axle bend? Not down. Those welds of his are gonna pop right off. And like Kamikaze said, steel to iron ain't going to last long. A truss across the top would have been a lot better, and even if he doesn't rock crawl, I'd imagine that truss on the bottom digging into the dirt and doing more damage.

Take a look at TNT Customs D30 Truss. That is one solid design and has proven to be a great investment to a number of my buddies.

The bending up of the axle tubes on impact is what makes an axle truss on the bottom of the axle work better. On top, the truss can be bowed/distorted by being pushed into itself. On the bottom, the forces are trying to tear the metal apart, or break the welds. If both are constructed equally well, the bottom side truss will be stronger. Obviously, top side trusses are more common, since they don't hurt GC, but are inherently not quite as strong. In desert applications, it doesn't really matter though. Check out some Jeepspeed XJ's and see what they run.

When you land a jump and the truss is on top the truss is being compressed together, if it is on the bottom the truss is being pulled apart. Trusses work much better on the bottom because steel's tensile strength is much higher than its compression strength.

guys im also plating it in. so It will have more weld area
