A carrier assembly is mounted on the spaced frame members of a tractor for movably supporting a fifth wheel assembly thereon. An integral one piece slide rail is secured to each of the frame members and has a plurality of individual rack sections separately welded to a U-shaped member of the slide rail. Each of the rack sections contain a plurality of spaced teeth. The teeth extend into a channel formed in mounting brackets of a carriage assembly of the fifth wheel to slidably mount the carriage assembly on the carrier assembly. A leg of the U-shaped member extends into a channel formed in the carriage assembly and is engaged by a set bolt to adjust the carriage assembly for various frame widths. A pair of stop assemblies are adjustably movably mounted across the ends of the slide rails of the carrier assembly. A pair of adjustable plungers secure the carriage assembly in a fixed position on the carrier assembly.
