Rear Suspension question. Drop spring or combo of spring & block?

[hewittca]

I think the HD springs are a good idea. I ran those on my last truck and they are definitely stiffer than the standard springs. With nothing in the bed they are great. I was also able to put several hundred pounds in the bed without even noticing a difference. More than 600 or so and I would start to hit rear to frame over bumps. Keep in mind, I also had 2" drop blocks and no notch so my suspension travel was limited.

Before the 4" HD spring/2" block combo I had standard 5" drop springs and they were way too soft, even with nothing in the bed.
