About This Product

The PullRite 2328 SuperRail is a mounting rail kit for trucks without factory fifth wheel prep. It provides under-bed brackets and rails rated at 22,000 pounds for PullRite ISR Series fifth wheel hitches.
The SuperRail design handles mid-range to larger fifth wheel trailers. It gives you a solid mounting platform that stays in your truck bed permanently, ready for your hitch whenever you need it.
Installation requires bolting brackets to your truck frame underneath the bed. The kit includes all necessary hardware. Most installations take a few hours with basic hand tools.
PullRite makes these rails in the USA with quality steel construction. A five-year warranty backs the product.
