It goes back to this:I am so confused by this sentence.
...TTB and Ibeam suspension...had terrible alignment problems, poor handling characteristics with terrible camber change through the suspension cycle.
...a true IFS (A arms), that is built correctly.
If you've designed a better IFS, tell us about it.
My point is: your race toys aren't specifically relevant to the OP's issue. That's not his goal. He doesn't (and I don't) have a 1000hp engine, and probably doesn't want one. And my opinion is that, whatever problems you perceive with the leaf TTB, it's still the best solution for the truck's designed purpose.The topic of this thread, and what I'm talking about, is a suspension that would be an improvement on the TTB under a turbo-diesel in a 3/4-ton working, street-legal fullsize truck chassis.
And that's all I'm posting. I don't see this as a forum to convince anyone of anything - it's just a forum to discuss things. The OP can do what he wants to with his trucks; you can do what you want with yours; I'll do what I want with mine; everyone else will do with theirs... But discussing the options, experiments, attempts, results, & alternatives benefits us all.I'm obviously not going to convince you...this is all just simply my opinion.
All of my TTBs/TIBs are aligned perfectly, and have been for many miles. My overweight heavily-modified 4.9L stickshift Bronco handles so well that I can drift it easily around a dry or wet clover leaf without leaving my lane. IDK how you're judging the camber change, but IMO, it's perfect. Both steering tires' inner tread shoulders bite in, just like you'd want them to. Yes, the travel is supposed to be limited, because these trucks weren't designed to go ballistic. If you keep all 4 wheels on the ground, the leaf packs allow plenty enough travel, while bearing all that weight. I can't imagine any way to improve it FOR ALL DESIGNED APPLICATIONS. And I don't consider reverting to an antique solid axle to be an improvement, because it sacrifices too many actual improvements within the TTB. Based on your pics, you don't consider solid front axles better, either.
