What harm could come from...automotive?

Turning the torsion bars on the front end of a 3/4 ton 4x4?
Also is there such a thing as turning them a little or is it all or nothing as I'll only need to raise the front about an inch.
I know the ride will be stiffer but what else could happen.
I'm getting new tires and an alignment at the same time.
It could be the simplest solution if my tires rub which I expect them to.

There shouldn't be any problems, that's why there's an adjustment bolt. But I do suggest turning them to the desired setting before you get your vehicle aligned.

Certainly

Tires
Torsion bars
Alignment

I had an '86 S10 4X4 that I maxed out the torsion bars on and didn't really feel a difference in ride, but the front end came up 2". I never got it aligned and my tires started to wear on the outsides after a while, but I got rid of it before I remedied the situation. Certainly helped with the extra weight of the winch and bumber I had on it.

I think the first step to aligning a torsion bar chevy is to set the 'ride height' which is a set value

After 150K, I tighted up the ones on my blazer 4x4. It was a little stiffer, but otherwise I just gained back my lost ride height. I drove it for another 55k before trading it in.

It is not changing a spring rate just the preload.

I had a 3/4 ton gm with the bars turned up, no real ill effects. The ride was harsher, cv shafts will not last as long, otherwise no issues. I beat the snot out if it for a few years and never a problem.
You could waste your money on the clocked keys which in effect are identical to bottoming out the factory adjustment bolt. People don't seem to realize that for some reason.

When you raise the vehicle via the torsion bars, 1in is ok. Align and keep driving. We will generally add a little more caster depending on the tire.
The further you go up, the less up travel you have. The upper control arms have drop stops. Stopping the upper control arm from dropping too far because the front end is coming up.

Your changing the steering geometry, and steering angles that do effect Yaw, turning radius , returning to center and performance type measurements.
Real world effect is not catastrophic.
The best addition you can make to compliment the lift and tire increase is to install a higher quality extended Shock for a lifted truck.
Are they 100% necessary, "NO". will your truck be happy, and reward you with a better ride, " Hell Yes "
