I have read every post I could on cranking torsion bars with all the pluses and negatives ( ie. green keys/stock keys , stock shocks/shim shocks/longer shocks , ride quality good/bad/ugly.
My goal is to put H2 wheels and 315/70/17 on. Would rather not do a lift , too old to climb that high:)
In all my reading have not read any info on the yellow jounces except that after cranking they no longer contact the A arm . Reading in the service manual it seems to me that they are an intrical part of the suspension system and give the torsion bars their variable rate. This may account for the harsher ride that some are having with cranked bars. Rather than re-invent the wheel I'll ask first ,has anyone adjusted the jounce to contact the A arm after cranking and what were the results .
I am only a back yard mech. so any and all comments are welcome , thanks

Yeah. What ticki said... I'd want to hear about it, too. BB

I just got my truck back from having the t-bars cranked up and it rides like sh!t now.

Ticki2, Put a square pc of metal between the jounce and control arm. same size as jounce alum. plate. there is a tab on the jounce plate, drill an extra hole where this tab is. you will have to drill into the upper control arm with this extra hole for added security. I used a pc. of 1/4 inch alum. Have had no problems with this system, and the ride improved dramaticlly. Hope this helps! BigRedD/A

Ozzy you cranked them to high 1 1/2 max and mine rides good. dave

i cranked my bars enough to almost level the truck (i absolutely hate 4x4s that sit ass high). doing so almost maxed out my bolts but the ride is exactly like it was stock, i can tell no difference. my cv angles are still good as well so i have no worries. sorry this doesnt directly answer your question, but i wanted to share my experience.

I'm not sure how many turns they put on them but, I'll deal with the ride. It's no worse than my old Ford, and it looks a lot better getting the front end higher. Now I need to get bigger tires.
