I looked in the Summit catalog and the Hotchkis swaybar set is over $500 but the other two, Addco and Suspension Technologies are significantly less expensive. any suggestions/comments on any of the above? is the Hotchkis worth nearly double the price, will I regret it if I dont put that one on?

Can you post the specifications of each type of bar? I'm sure that they are not all the same.

The Hotchkiss bars are hollow. They are very light, but they don't work any different. I have an Addco, it's a solid steel rod 1 1/8" thick and it weighs a bunch, but as you said, cost a lot less and works just fine. I'm not familiar with the third one.

I was under the impression that hollow was not good, solid would transfer the load better. am i mistaken? (I often am!)

Only if the bars are the same size.
example...
1" solid bar ='s about the same torsional stiffness as 1 1/8" hollow bar.
So if you run a hollow bar the same dia. as your old solid bar the hollow bar wouldn't transfer as much weight.

67-69 Front Antiroll Bars
I just received an E-Mail from Hotchkis. Their hollow front bar is 1 1/8" in diameter by .120 wall.
Given that information, I've figured the bar rates and resulting wheel rates in lbs, and weight of each bar.
Dia. . #at bar #at wheel calculated weight of bar - lbs
11/16 . 144 . . . 109 . . . 5.6 stock
7/8 . .. 377 . . . 285 . . . 9.2
1 . . . . 643 . . . 487 . . . 12 common aftermarket size
1.125 . 636 . . . 482 . . . 6.2 (hollow)


FYI I run a 1 1/8" solid bar from Hellwig. It's way to heavy for a stock set up or runs down the track.
