I believe yes. Think of it this way: 1/8" 1 x 1 angle is stiffer than 1/4" 2" strap if both are the same material.Mace said:

but that only works out because you are using a 1" thick section (in profile) and comparing it to a 1/4" thick section..Rock Taxi said:
figure the 1/8" angle has a Gussett
LOL! That's kind of my point.
It seems like gun drilled, tubing, a straw is more rigid than solid of the same dimension.
Oh well, I'm no expert or engineer and am probably wrong.

Here is a link to a bender.
Look at the comparison to what the max sixe tube can be bent (not pipe) vs the maz size barstock.
barstock is always smaller in Diameter.

Go with the 2x2x3/16 or 1/4in square. No problems then. No bending issues. No worries. check out this guy
http://www.claytonoffroad.com/ He usese 2x2x1/4in wall tubing for his suspensions
The stiffness(modulus of elasticty) of a material has nothing to do with the yeild point of a material. You can change the yeild point of a piece of tubing. You can not change the stiffness of the same piece of tubing with out modifiying the geometry some how. All steel has the same modulus of elasticity(30 Mpsi), it is considered a physical constant of the materail just like density of a material.

it might be its about 4 foot long and i got 2 lengths .I decided to use 2x2 for lowers and the solid is getting tapped and I am putting heims in both ends

The modulus of elasticity is directly proportional to the yield stress of the material E=yield stress/yield strain.
All steel does not have the same modulus of elasticity. It is a material property specific to the material's composition, there are different types of steel, depending on what alloy they are the modulus will be different for each one, 28,000-30,000 ksi is a common range for steel.
Max torque/max stress is inversely proportional to moment of inertia, which is a function of the cross-section/geometry of the shape. Therefore a higher I, the lower the stress.
All solid material of the same diameter/outside dimension will have a higher moment of inertia. It's the strength to weight ratio of solid to tube that makes tube seem stronger. A hollow shaft compared to a solid shaft of the same material and diameter and loaded in the same manner will see 15% more stress but have 36% less weight.
To answer the question, the moment of inertia for your 1.25" dia. rod is .1198 in^4 and 2" x 2" x 1/4" wall is .9115 in^4
I'd go with the tube it will resist bending and torsion better than the rod.

Then turn the OD Down in a taper to the middle to cut the weight and increase coolness points.
