I have a 07.5 chevy 2500 my truck is riding rough. The tires are still good on them. It has the torsion bars cranked up with stock shocks and no keys. Do I need bigger shocks? And yesterday when I brake the truck is starting to shake and I don't know why?

This is a dodge forum, however, trucks in general suffer from similar issues regardless of brand.

Tires can cause rough riding conditions if over-inflated.

Cranking torsion bars can also cause a rougher ride, and broken torsion bars and other suspension parts.

Longer, rather than bigger shocks are sometimes needed when lifting suspensions. Shocks don't provide weight carrying capacity and are often confused as providing lift and an increase in payload. Shocks dampen spring recoil, or in your case, torsion reflex.

The shaking during braking is an alignment issue relating to your increase in torsion bar resistance (cranking) which increased ride height and is forcing the top of your tires and wheels to lean outward, which also increases toe-in. A good alignment shop can remedy this and will usually suggest you reduce the cranking of your torsion bars and instead install a proper lift.

The 07 era Chevs had a good front suspension design and should be able to accommodate a slight cranking of the torsion bars....
