Trac bars

What sizes?
How are you guysw attaching the bars to the rear axle? Underneath the U-bolts?
Any all ready made brackets out there for DIY guys?
Here are some pics of mine, I used ballistic joints on one end and bushing on the other, both are greasable.

dang those look nice...
if you go to duramaxracing.com (Mike Tomac's website) and look at his. I have those same rod ends, I just used 2"x0.125wall" square tubing instead of the round DOM like he uses. I'm not positive but I think Burkhardt stocks those same rods ends. They are from like semi truck track bars I think.
If you can't find those... places that sell offroad components have those ends like Dmax15 is showing on his. I think Ballistic is one of the manufacturers of them. If you get on Pirate4x4 and cruise the shops there, there's several of them that sell weld on tabs and brackets and all that kind of stuff.

After digging around i think i might try summit brand 3/4 rod ends on both ends, qa1 tube adapters, and some 1 3/4" od, 1 1/4" id .25 wall thickness dom tubing and see if it holds up to pulling.
The bars dmax15 made look good but it doesn't sound like he's trying to sell them on this forum.
If it were mine, I'd go bigger diam. on the tubing but I like 'em stout with little or no flex. To help with that, keeping them as flat as possible should help the round tubing with deflection. The more axial the loading on them, the better.

no sir. its not like trying to crack an egg in the palm of your hand type deal.

2" does cost a little more but i suppose might as well go over board the first time and not have to make 2 sets.
square tubing is stiffer than round tubing given the same axial load, rod ends, etc etc.
ultimately, I'd go square tubing if I were you but if its gotta be round (I admit, it looks a little bit better being round) then I'd go for some 2"
And yes, square absolutely is stronger than round when talking about the compressive forces being applied and equal size outside dimensions.

You would have to use pretty thick-wall square tubing for it to be stronger. Every set of bars I've seen made out of square tubing have bent, both single bars and triangulated bars. The first set of bars i built for my truck were 1/4" wall, 1-1/2 box and were bent front to back and side to side. All the bars we build are now made out of either 3/4 i.d. DOM tubing or usually 1-1/2 i.d. DOM tubing with heim joints.
If they are the same material and same size square is stronger. If you go to s larger round bar that doesn't mean it's stronger because it held up
