The rear end of my truck is extremely stiff. When I go over a bump at all speeds (usually go over them slow), the rear end drops like a brick and everything in the bed hops around. I've got a set of Downy long AAL and a set of Rancho 99144. Is it the AAL or shocks that are causing this stiff ride? Is there anything relatively cheap to do to fix it, or am I better off getting a set of deavers or alcans with some bilsteins?

I'd suggest removing the AAL and putting a shackle in. See how it rides then. If still to stiff then look at diffenrent shocks.

sorry, I disagree. and I said to remove the AAL, not to add shackle with AAL. have you tried removing your AAL adn see how it changes the ride???? might want to try.
Probably need to relevel truck somehow w/o AAL. or jsut use shackle lenght to re-level. Dont' go too long on shackle.
