New OEM Rocker Protection

While they're new....you should build a jig off them, so you can make more. The GM rails are the best IMO. They are plenty strong and allow you to support the truck with jackstands so you have full access to the bottom of the vehicle... (for SAS and SOA mods).

A little bit confused, what do you mean by build a jig off them?

A jig (welding fixture) will locate all the mounting points just like the H3 frame. This way you can build numerous rails that always fit perfectly...without having to remove your rails to build them on the truck. I use similar jigs for bumper fab.
