Well the stock keys can only be tightened up so much before it tops out. Once it is toped out then that is where the Indexed Keys come in. It indexes the bar so you can turn the torsion bar MORE than the stock key would allow.
I don't know the true numbers/rates but say under stock the bar is under 1,000lbs of weight/pressure which is also stress. When you crank it up 2 inches the pressure goes up to 2,000lbs. 4in 3,000lbs of pressure. The more pressure you give it the more lift you get. So stock stress is not the same as lifted stress. It is completely safe as long as the control arms are not maxed out and as long as the torsion bar is not bending.
Now I don't know for sure if you can top out the stock keys on a 2nd Gen. On 1st Gen you can very easy.
A body lift will lift the body and allow you to lower the torsion bar some. If that is your goal.
Stock truck IFS sucks for anything serious like rock crawling or racing. Stock can do anything with light throttle. When you need more strength then stock IFS then you would go with a SAS.
But IFS in the right conditions are stronger and better then SA. For one IFS has 6 joints in a Constant motion That is where the CV comes from. Vs 4 joints with SA. The individual articulation doesn't disturb the other side.
What makes stock IFS weak is the CV joints can come out of the housing under high articulation. The joints are smaller than SA joints due to space. The IFS ring and pinion are smaller then the good SA's.
Remember the Humvee use IFS. And we know those go threw the hardest stuff we have on this planet.
