Torsion Bar Information
I received the attached document from Truxxx Manufacturing and it does provide some helpful information on how the torsion bars work.

I currently have my bars adjusted 2 1/2 turns and I just ordered the Truxxx H3 Lift Kit. Should have it installed next week and I will provide feedback.

Re: Torsion Bar Information
Good info,
I adjusted mine 2 turns and seems OK. Some lift to front end and no significant stifness noted. In fact seems the same ride so far. Thinking that if foul weather or catastrofic conditions occur I will crank it to the max to get up high to beat the water and come what may...
Regards,

I just read the Truxxx report and while most of it is true that style of torsion key is not used in the H3. The H3 has a key bolt twice as big and doesn't force the end of the key up as in other gm's, It pulls the key down as you tighten the bolt. One thing I have noticed with the H3 is as you tighten the torsion bars the ride ends up getting rough...This is happening because the shock is "topping out". I cranked my torsion bars up 7 or 8 turns and untill my extended BDS shocks get here shimmed the shock lower in the mount so it is not "topping out. I also built a set of rear shackles that are 2 1/2 inches longer then stock to raise the rear and inch or so to match the front. In this pic I have the H3 with 315 Coopers, torsion bars cranked and shackles installed.

I believe everyones concern is wanting to know the "acceptable limit" a torsion bolt can be turned without premature damage to connecting parts or the torsion bar itself. We (H3 owners) don't have any long term studies or verifications. I believe most, like me, are just winging it and scared to go beyone 3 turns. You went 7 or 8. For some this may be risky, others acceptable.
Please give some addition information:
How long ago did you do the 7 to 8 turns ?
How is the current ride and do you believe it will be better with new shocks?
Anticipate any wearing problems?
Other concerns?
I purchased the Truxxx kit and it gets installed on 8/2/06. I'll provide feedback and photos.
Thanks for the input of the Truxxx report.

Not sure how many people are interested. I still have to get my shocks and install them. I also noticed that I will have to lengthen or at least arrange to allow the rear wheel speed sensor wires to travel the extra 2 or so inches that the shocks will allow.

Chris -
Do you have pics of the sensor wire issue? How about the brake lines? Are there any issues with them?
Thanks!

What did you use to lower the shock top mounting position?
Do you have a part # for the BDS shocks you ordered?
Thanks!
BTW here are my results and findings from 1 year ago...

Do you have a part # for the BDS shocks you ordered? For the front a 55602 and the rear a 55719. both BDS #'s in the 5500 series shock.
Thanks!

Re: Torsion Bar Information
Humdoug - When are you having the Truxxx kit installed? I am very interested to see the results (I imagine that others are too ).

Re: Torsion Bar Information
We've been doing these to the H2 and all the 99 up GM trucks and SUVs.
It just changes the a arm location in relation to the torsion bars.
No different tension/twist in the bars since they are carrying the same weight.
put a 300# bumper or a snow plow on the front then turn the bars up to the original level, the bars have more load on them.
As said before just have to watch topping out the shocks.

Re: Torsion Bar Information
I did the torsion bar adjustment today. Did two and half turns and gained 1 inch in ground clearance. It is getting an alignment right now. Any ride difference is barely noticeable and looks great!
