Savvy Offroad upper and lower control arm measurements if you choose to build them

Because you can't.

Ah! You got me. I'm ruined!

That would be a very heavy arm for one that works for a mid arm lower. 1 1/8" hole in a 2" diameter tube gives us what, 7/16" wall thickness? I already don't like how heavy .250 wall is. Last time I saw 7/16" wall thickness was on the J arms, but they weren't 2" OD.

I’ve not weighed my short arms vs a savvy short arm set. I just wanted point out that it’s not absolutely required to have inserts.

Weight should always be considered and for the record, if I were making my own set of arms, I’ll use aluminum
 
You're an aluminum supremacist.
If that means I understand how and why to use specific materials to best utilize their properties to my benefit, then you are correct.
Lower control arm roughly specified below in DOM steel and 7075 for comparison. Steel weighs 9.34 lbs for a 24" arm plus a bit more since tube adapters are heavier wall thickness on each end. Aluminum weighs 7.38 lbs minus a bit for the material removed for threading. The aluminum arm is about 38% more resistant to bending than the steel arm and weighs slightly less than the steel arm.

I am going through the struggle of steel vs. aluminum for my control arms right now. I had originally bought steel for the cost savings over aluminum and no other reason. Two things stick out about Blaine's response. The weight savings and bend resistance comparison. The cost is minimal when looking at the big picture, but the bend resistance part of it is huge when wheeling where it matters.

What most folks miss in the aluminum versus steel discussions is how the weight difference can be used to our benefit. Because aluminum is 1/3 the weight of equivalent dimensional steel, you can double the thickness of something like a belly skid and get a bunch more goodness and still weigh less than the steel. To get the same weight, you would have to triple the thickness of the aluminum.

If you pick 1/4" for a belly skid in steel, that means you can bump up to 1/2" aluminum in the 6061 T-6 grade, still be lighter and with a large increase in all the things we need a skid to resist. We don't use stuff that thick since 3/8" 6061 T-6 works for our hardcore applications so you still wind up with something "stronger" and lighter.
 
I’ve seen it at $19 a foot. I didn’t look at that price was just looking at that they made it that size.
Just because I'm bored. You give up about a 1000 lbs in bending resistance by dropping 1/16" at the OD. The smaller stuff drops another 1000 if you switch to point loading in the center.
