The rear rail is available as a complete assembly (1). It consists of an outer panel, two inner reinforcements, a rail extension and all necessary component mounting brackets. The outer panel (2) and rear mounting brackets (3) are also available separately to facilitate sectioning. There is a crossbar that connects the two rear rails for added strength and rigidity.

Complete rear rail replacement can be performed by drilling out all the factory welds. The outboard flange at the forward end of the rail must be cut in one location and bent upward, and the bottom flange of the crossbar must be bent downward. The rear rail can then be lowered from the vehicle. When installing the service rail, the outboard flange must be cut and bent up, installed, then straightened and aligned. Weld as necessary.

Rear rail (1) sectioning procedures can be used to repair the rear rail if just the portion rearward of the crossbar is damaged. The rear rail outer panel is available separately for sectioning (2). The rail extension panel must be purchased separately (3).
