I have a 2000 (old style) Chev 3/4ton diesel that I want to upgrade the shocks on. I'm interested in your recommendation on a shock brand/model for improving the ride control. I don't want to make the ride stiffer, because there is plenty of stiff already. Alternately: I moved up from a Z-71 diesel, and I really liked the Z-71 shock package on that truck. For the experts out there, will the 1/2ton Z-71 shocks fit the 3/4ton? Thanks in advance.
