This is an eight piece kit constructed of 10 gauge cold-rolled steel. These weld on notches are a universal fit for almost any truck and are a must to if you want to lay your frame on the ground. If you don't want to cut the bed and drag frame, simply cut the notches down to the size you want before welding them in. The notch provides the extra bracing required for mounting our rear bag brackets, and make for a stronger than stock rear frame section.
