Ive tried a few different shocks on this truck. The bilstein 5100 and a couple models of rancho shocks.
One thing Ive noticed with the ranchos is that the adjusters only seem to affect compression damping, not rebound. Rebound is my main problem on this truck, it wallows all over the place and its not really safe IMO.
Has anyone tried inverting the rancho shocks to see if the adjustment has more effect on rebound?
Not sure what the internals of this thing look like, and if it will operate properly upside down. Cant really get much info online about this either.

 

I don't know what your rancho's look like inside either, but I did find basic information on how the different types of valves work and which one can be flipped, which ones cant here.

I didn't think it had any difference in compression vs. rebound dampening though, because (in my mind) the valves are submersed in oil either way.

 

I had a set of ranchos I think 9000's. if I inverted them they would not dampen or rebound at all. Hey just stayed stiff as a brick.
