My truck wheel hop's "bad' in damp road conditions!
The worn spring bushing is a thought, but that axle to spring block is probably more the problem then any thing else,......... Hmmm, if the lower part of the caltrac was atached to the axle......some how so that the axle leverage was controled by the caltrac and the block was just there to support the truck!?

I don't mean the bushing, I mean the springs themselves. Weaker springs are more susceptible to wrap. When I got it, my Plymouth was so bad with old worn out springs on long shackles it was jumping around like a carnival ride if I got on it hard enough. Downright dangerous. Fixed that real good! 
That's the whole idea, that's what the bars do - lock the axle in position, torsionally so it can only move up and down with "normal" suspension travel, nowhere else. The hopping is "abnormal" suspension travel induced by torque twisting the axle as the springs wrap (to some degree), then let go when the tires lose grip and (once again) BOING!
The only functional difference between the long frame mounted bars and the Caltrac is the way they transmit that torque. Long bars transmit it into the frame. Caltracs transmit the force back to the spring in the opposite direction.

Ya,
i don't now why but i was picturing the block and spring on the under side of the axle not the top
I also, went and look at my Super Stock spring and there is not any space between the last leaf and the main eye loop.
I thing weather the leaf spring was old or new the caltrac would work the same right? just the ride hight would be different!

Nope. Doesn't affect the ride height or suspension travel in any way whatsoever. That's the nice thing about the Caltracs. You don't even know they are there in normal driving. Other leaf spring solutions will have some compromise. Frame mount bars will bind if they are not long enough - reeeaaallly long. Slapper bars and snubbers are less effective, and limit suspension travel to some degree causing a rough ride.

before i put the adj pinion snubber, the Super Stock spring where real smooth ride compared the the home made Super stock spring that i had made up from a couple set of spring that i had laying around!
then i installed the adj pinion smubber,set to "race hight' (1").......now i have no suspention to speek off.
luckly it isn't diven on the street any more!
