Guys these things are as tough as they come. Kert made a special set for my 14 bolt several years ago as I offset my center pin with F550 spring for truck pulling and they draw alot of positive attention due to the craftsmanship and beefiness when people look under my truck.
The only thing I would suggest is drilling drainage holes in the front prior to installation (mine always seem to collect dirt/water and are rusting on top even after etching primer and paint), but that is an EASY fix.
Kert, thanks for the awesome work.
