Silverado HD front end lift
Does anyone have experience lifting the front of the new HD's? I've seen the 1 and 2 inch lift kits. And the local dealer told me that they can rotate something in the front suspension to raise it u...

Why does the ride quality suffer if the torsion bars are adjusted for a higher ride height ?
It seems to me that the higher adjustment is not making the torsion spring stiffer , but rather just increasing the ride height .
If that were true , then would the ride be softer if the torsion bars were adjusted for a lower ride height ?
Imagine a truck that is sagging in the rear. If you were to add another leaf spring it would raise the rear of the truck higher and make for a stiffer ride. Same thing for the torsion spring, but instead of adding a leaf to make the suspension stiffer, you are just winding the spring up tighter. And yes, if you were to "loosen" the torsion spring, it would provide for a softer ride, but in the case of the Silverado suspension, you would end up riding on the rubber bump stop.
That doesn't make sense to me. You cannot change the spring rate of a torsion bar just by rotating it. It's like adding longer shackles to a leaf spring.
Any change in ride quality is from the change in geometry of the a-arms at the ride height. If their leverage against the torsion bars decrease the ride will get rougher.
