Kid: The 3200 is still rated as light duty 1/2 I think back leaf springs are the difference.

So any of your vendors, Brothers, Chevy Duty, CPP, ect. carry those shocks. I can't remember but I think a couple of the guys here got them also thru their local tire dealers.

Do not go w/coil shocks the ride gets hard.
