GM's only reason to use torsion bars in the first place was to save some room for their IFS setup. it made it easier for them to get the front axles to the hubs without having a shock and spring in the way. it has worked for 25 (if it isn't broke, don't fix it mentality)
Most people wouldn't even look at GM IFS truck for building a cheap guy sand/mud truck. The parts just don't hold up under a lot of power, just ask the Dmax guys how long there tie rod ends last. 3/4 link solid axle in the front is the best bang for the buck if you want something that will stay together.
BTW, Atomics setup is still a real good idea for the lowered trucks and the ones that that like to stay at the stock ride height. I will end up with a kit this year. Just need to find a good heavy quality shock. Maybe look into a Fox or King and see if they have something that's short enough to work.

Here is a good spring rate calculator....

Look, I really didn't expect to face this much of problems with the Tbar! But you addressed alot too, for example:
1- you agreed that Tbars can deliver " reason to use torsion bars in the first place was to save some room for their IFS setup. it made it easier for them to get the front axles to the hubs without having a shock and spring in the way. it has worked for 25 (if it isn't broke, don't fix it mentality)"
2- So where is the problem? You answered
"The parts just don't hold up under a lot of power, just ask the Dmax guys how long there tie rod ends last."
True, I did replaced the ends and every thing else but it hold for a month or so and back to square Zero! My friends know how much effort has been done but again I can't hold it foe example: 2 months ago I replaced the front shocks from stock and used the Monroe sesnatrack now it dead again!! And yes the end are screaming laud!!
3- What we could do?? Your Decision:
"3/4 link solid axle in the front is the best bang for the buck if you want something that will stay together."
Ok, what if someone can't do that? Not possible to find a shop to do such a mod and the needed parts aee not found!?
Thats is the real question, please I am not here to attack I am here to discuss it so I could find a solution just like you
Thanks,,

The IFS actually isnt bad as long as you keep the CVs level. Its when guys crank the hell out of the torsion bars and all the geometry is off that you break things constantly. My truck has around 1100rwhp and ive done dozens of full powered 4wd launches on a drag strip with drag radials and never had a problem with the IFS. Only mod I had as tie rod sleeves and I wasnt convinced those were even needed.
Whats wrong with QA1 shocks? Mine work fine...
Thank you!
Could you please tell me which tie rod sleeves did you use? I think some how you got to part of the solution, I noticed like if I needed something woukd do this jop,,
