California Suspension torsion bars
I may have misremembered the hex offset.
Now I'm thinking the Mopar Perfomance ones were 30* offset and the California Suspension ones are no offset.
At least the ones I have. I only have had that one set.
But that would explain why there was slack with the control arm down, and why I had to crank them in so far to get the ride hieght.
See what yours is.
I should be by the garage tommorrow. I'll try to remember to look at them.
