Sway Bar Rates

[Track Junky]

I'm in the process and planning to relocate my front sway bar to the top of my frame rails. In order to do that I need to know what my existing sway bar rates are so that when I go to a splined bar I know what size bar and length of arm to go with. Also going to drill 3 holes in the arms at 1" apart for adjustability.
I called Hellwig, DSE, Hotchkis, and Global West and this is what they gave me.

Hellwig 1 1/8 Tubular 600 lbs/in
Hellwig 1 1/8 Solid 720 lbs/in
DSE 1 1/8 Tubular 1532 lbs/in
Global West 1 1/8 solid 1279 lbs/in
Hotchkis 1 1/8 Tubular 750 lbs/in
