Ain't no engineer here, but a hollow axle will resist bending better than a solid one. I believe it has to do with #1 the flexibility, #2 the surface area both inside and out... Plus the missing 3/4" bar, assuming you're using .25 wall axles, is equal to about 5.5lbs. CR

It bent, no crash just bumps, at that point I redid the whole rear suspension and used a piece of 4340M also called 300M ....it's has held up fine. I seem to remember the certs that came with it showed a tensile of about 280ksi and a rockwell of about 52-53 on the c scale. Maybe overkill but I haven't had to mess with it since.
