Is there a reason you wanna go with the pack with 6 leafs?
Well, I do pick up yards of gravel/rocks/mulch/dirt etc. with the truck, so the weight carrying capability is definitely necessary. Max load on the springs are as follows:
4 leaf - 1425 lb
5 leaf - 2025 lb
6 leaf - 2235 lb
8 leaf - 3300 lb
A yard of rocks or gravel weights about 2800 lb apparently, so that might explain how the springs got bent in the first place.
Anyway I'm mostly fighting about whether to get 6 or 8 leaf springs. I want to find someone who did do 8 leaf springs, I just wonder how bad the ride got, seems it might be pretty stiff at that point. if its intolerable, i could just deal with 6 or 5 leaf springs and just cut my loads down a little. and I still dont want to get my truck lifted all funky from thicker spring packs, so can I avoid that with longer shackles?
