2000 Bumpy Jimmy. Wanting to remove the factory z85 springs for a better and lower ride, mainly because I'm getting old and the city stopped repairing the roads in phoenix (well they pave over the ok ones, and never fix the crappy ones). I went for removing the one rear leaf above the helper spring and 2" drop blocks. End up with 4 inch drop out back, looking good. Install some Moog 81000 springs up front, hoping for 2 or 3 inch drop. Maybe 1.5 inch drop over the z85's. Way to much butt dragging for my taste, so I take out the 2" blocks. Almost level, actually like the look. Problem is it still rides like a dump truck with no load. Front end rebuilt a couple years ago, new tires and shocks. Tried lowering the tire pressure to 28 front 25ish out back, no change. No doubt the worst riding truck/car/suv I've ever been in. It's really good over speed bumps now, but potholes or man hole covers, it's jarring. Going to try new sway bar end links, since the old ones are hard as rocks. Next will be different shocks, got the cheap delco's now. So if you are looking at the Moog 81000 thinking you're going to get 2 or 3 inches lower then the z85, it didn't happen for me. Kind of makes sense if you look at the numbers, more coils and same thickness as the z85. Have a set of moog 5664's, they look and measure very close to the z85's. Going to guess the 5662's are close to stock springs. She does have a lot of miles, 230k, so the interior plastic being noisy doesn't help.
