Fifth wheel rollers mount into a set of base rails already installed in your pickup truck bed. They offer a sturdy mounting place for your 5th wheel hitch. CURT rollers are also true rolling units. They roll on actual wheels rather than sliding on rods as seen in competitive models.
The roller smoothly rolls the head forward and back and locks securely into each position. CURT rollers provide up to 12 inches of movement, unlike the more common 10 inches.
