@hot cocoal...
The ride was that bad?
Not only was the ride poor, in my experience with a couple GM rigs, due to cranking up the torsion bars to level out the truck there has also been premature IFS part failure and excessive and poor tire wear as well.
Forget about efi live tuned boosted launches...a stock trans race tune has the potential to pull apart the c/v joint when they are leveraged out like they do when you crank up the torsion bars
As Andrew pointed out, a better shock will make a difference in ride quality, more so if the torsion bars aren't totally cranked, also use an extended lower shock mount if you plan to level the rig out and are using stock length shocks.
You'll get a significantly better ride using an upper control arm kit, along with the "ability" to go even higher, or maintain some ride quality and save your c/v joints a tiny bit.
Keep in mind, you typically get what you pay for, there's no single miracle part that's gonna make the truck the way you want, at least not in a well rounded fashion anyways
I started out with Cognito upper control arms maxed out, ball joint on top of the arm and extended shock mounts and +1" bilstien shocks, couldn't do a boosted launch in a built trans tune ( appx 525whp) with out busting a half shaft and it rode like a first gen dodge on 19 1/2" rims and highway tires
Maybe not that bad, but it sucked, and I was running a tire with a nice big sidewall 285/75/18
That tire size is what started it all, as it's the tire, or wheel/tire aspect ratio I feel looks "right" on our trucks, JMO
This is all IMHO, my perspective and what's acceptable to me
Now I'm runnin a full Cognito 4" lift with modified spring pack, gears, custom 4x4 drive shaft
And it rides better than a stock truck does
well, that's relative too, it rides the way "
I" want it to
