I had some pro comp mx-6 on a 1/2 ton a while back, they were adjustable, sorta
thought they were crap
as for the best responding "fixed"shock,
Fox 2.0 emulsion up front and 2.0 resi's in the back
That set up was my all time favorite
I would love to try some q1a's someday
The cognito spec'd bilstiens are cool, way way better than stock and the proper length
they are considerably lesser of a shock in comparison to the fox shocks
