moregrip Posted May 7, 2006 Author Report Share Posted May 7, 2006 If I can remember I can check tomorrow at work since we have some HD lowering keys and I have my stock keys laying around somewhere. <{POST_SNAPBACK}> did you happen to remember? what I'll probably end up doing first, is taking some tension off my torsion bars to see how that feels.

moregrip Posted May 9, 2006 Author Report Share Posted May 9, 2006 anyone else willing to crawl under their truck to see what torion bar code they have? I was hoping to get a few inputs Link to comment Share on other sites More sharing options...

I was hoping to get a few inputs <{POST_SNAPBACK}> This is from Mr. P the second post in this thread. The bars in my truck ('03 SS) is YT; if you find out what their rating is please post here, I'm considering going heavier because I have lowered my front suspension. Mr. P.

moregrip Posted May 29, 2006 Author Report Share Posted May 29, 2006 so far I have two conformed YT codes and it looks like the T-bars are the same length on the SS and 3/4ton applications, about 4' 7"...... I measure the T-bar Hex at about 1 3/4" Link to comment Share on other sites More sharing options...

I have heard relaxing tb's too much is dangerous... lastly, what color keys come on the SS's? Link to comment Share on other sites More sharing options...

I have heard relaxing tb's too much is dangerous... lastly, what color keys come on the SS's? <{POST_SNAPBACK}> Well first your truck has purple keys correct? If so installing SS keys will only lift it. As far as relaxing you mean turning some adjustment out of them? I couldn't say weather or not it would have the same effect as the yt's but I don't see why it would be dangerous? Is this because when you turn them down far enough you can jack up the front of your truck and have them be lose? If this is the reasoning I have thought about this as well but I never plan on getting air in my truck either, if you were to get enough air for them to be lose you would have to hit something while in the air moving forward hard enough to dislodge the t-bar and have it slide out the front of your controll arm. If this ever happends you have much more to worry about than your tortion bar comming out. Link to comment Share on other sites More sharing options...
SS_bnoon_SS Posted May 31, 2006 Report Share Posted May 31, 2006 Would relaxing my current tb's yeild the same effect as installing the YT's(next spring down)? I have heard relaxing tb's too much is dangerous... <{POST_SNAPBACK}> No, turning the adjustment bolt does not change the spring rate. Think of the adjustment bolt/keys/pork chop as a weight jack. It will change the height of the vehicle by changing the angle of attack of the spring, but the spring will retain almost exactly the same stored energy with minor differences for weight shift (front end goes down, it will carry ever so slightly more weight). Unless you lower it enough to rest on the bumpstops, your springs will have the same stiffness as before. Link to comment Share on other sites More sharing options...

The reason is because the tortion bars have preload on them from the factory which makes them act stiffer than they really are. When you release the preload then the spring will be softer once the preload is released then yes it will have the same spring rate at any other ride height. Your ride will soften a bit but not much to make enough of a difference IMO. Link to comment Share on other sites More sharing options...
TBSS Posted June 1, 2006 Report Share Posted June 1, 2006 I did a lot of research into torsion bars and spring rates when I was looking at lower my Avalanche. The definitive answers I got were: - Whenever you adjust torsion bars, you change their spring rate - You cannot adjust or change height without also changing spring rate - Changing via keys or bolts is irrelevant, both change height and spring rate Anyway, don't know if this helps, but I thought I would offer what I found.

moregrip Posted June 2, 2006 Author Report Share Posted June 2, 2006 thanks guys, my question isn't so much spring rate related, as it is related to relieving more tension than is safe. It's my understanding that a certain amount of TB tension is needed to be safe and for the spring to function correctly. If true, I would only have so much room to play with before it would make more sense(safety wise) to step down to the next lighter spring to maintain the min required amount of tension to stay safe. Does this sound familiar to anyone? Link to comment Share on other sites More sharing options...
