Unlike a garage door spring the vehicle went up with the same resistance unless you keep on cranking and top it out ?

The bar doesn't twist, it rotates. The front of the bar will rotate the exact amount as the rear. The bar is not loaded any more than it was. You would have to add weight to the front of the truck to load it more, or completely top out the suspension and keep cranking.

Ok, watch this, shows exactly how it works...

WTF did we not cover over and above that video? Did you even bother to read what me and snap wrote? I have installed 4 lift kits on GM torsion bar system trucks...that video does nothing but dumb down what we were saying in the first place.

The reason that the GM trucks ride rough after you crank the piss(or install keys) out of the torsion bars has nothing to do with loading the bars more. They ride rough because the control arms are no longer level and now you have to overcome the steep downward angle before they start to move. Rotating a torsion bar is not a viable way to lift the front of the truck.

To add to this, the higher the bars are adjusted, the less "drop out" the A arms have making the ride even worse.

whatever you think...

It's pretty elementary.

yes, the bar twist to form the spring...

So there's a plane...

When the torsion bar is installed it is partially preloaded after removing the loading tool. So the adjuster bolt is installed, the vehicle is lowered down and it settles out. Now, I will talk in your terms...that is the initial "twist" as you call it. Now if you adjust the bolt/ride height the WHOLE BAR ROTATES...meaning it "twists" the same amount on EACH END OF THE BAR. Now, that ride height is set, the only time the bar "twists" more or less is under compression and drop out. I am done here. :kiss:

I cant actually believe that I am wasting my time with this on a boat forum...but it is november.

Damn you GM for replacing leaf springs/solid axle with IFS/torsion bars!!

It's hard to believe that a 30 yr GM mechanic and someone that programs robots for a living doesn't know how a torsion bar front end works. We must be idiots Jeb.

guess we are just bored...all winterized here...

I did stay at a holiday inn express last night!

Tucking my STV away this wknd...not looking forward to snow.
