I get all my stuff from www.polyperformance.com. Good prices, fast shipping, and Dave is a knowledgable guy.

You could also use threaded rod couplers.

That's what I have. I also used 2"x.250" DOM and have 1" threaded rod couplers welded in. I used a combination of plug welds (rosette) and a fillet weld.

The couplers are about 3 1/2" long and the point to point outside dimension is just under the 1.50" ID of the tube.
If you wanted to go with 1 1/8" rod you might be able to grind down the points to fit it inside also.

Another possibility is to go with thicker walled tube and bore and tap the ID to the thread you want (1 1/4" etc.)

I use 2.0" x .25" wall, then a 1.5" x .120" wall sleeve inside. Then I weld in my 1.25" all-thread.

If you can find some 1.75" x .25" wall DOM or Seamless tube, it would be perfect for use with the 1.25" all-thread. I couldn't find any fr my latest project, so I used the method above.

I also got some stuff from www.polyperformance.com. He was out of the larger threaded inserts so I got them from www.xxxtraction.com . They are also available from www.crlcustoms.com .

Those are the only 3 places I found for the large ones. www.spidertrax.com has smaller ones for stuff like tie rods.

Edit: Fixed a link.

Try the guys at Chassis Engineering here in Florida...www.chassisengineering.com They are drag racer types, but have a ton of stuff including tubing. Reasonable and professional every time I have delt with them.

Ted,
Don't be afriad to consider just cutting the threads yourself. Get some tubing with the right ID to accept the right sized tap. Any machine shop will do it for you for very little money also. All of my stuff is cut including the radius arms & steering links. I trust this more than a tube adapter welded on the end.

I dont agree with that!You will either end up with very heavy arms or thin spots.I used grade 8 alloy rod couplings machined to fit inside my tubing.The cost of cutting threads and the quality of the threads also need to be considered.

BTW:thas 1 1/4"x12 Chromoly allthread!

I have always been told that threads cut on a lathe are much stronger than those cut with a Tap...don't know the logic behind it, just one of those things I heard somewhere. :confused:

BTW I have had good luck with these guys www.chassisshop.com

You can get the all-thread from www.polyperformance.com. (It's B-7 grade all-thread, the good stuff.)
