[GMCnet] Saginaw steering gearbox-spool valve torsion bar

[Bob Drewes]

Howdy;
The Saginaw steering gearbox has a spool valve assy with a torsion bar to control the spool valve. I had a list of various spool valve assy and the various torsion bar tensions for various vehicles, now I can't find that list. I have talked with Fritz Slama and Don Wirth on this topic, but can't find the GM parts list that I had for the various valves/torsion bar. I would think G Kosier would have some info on this, what say ye Gary?

Bob,

I just did a quick Google search and found this table which gives torsion
bar diameters in an assortment of vehicles -- no PN's though:

How'd your ride height come out after installing the 1-Ton?

Thanks Ken for the info on the Saginaw boxes and the torsion bar for the spool valve.

I do not have any height problem with the 1 ton install, in fact I have about 3/4" yet of bolt travel for full height.
