About This Product

The PullRite 2336 SuperRail is a mounting rail kit for trucks without factory fifth wheel prep. It provides under-bed brackets and rails rated at 20,000 pounds for PullRite ISR Series fifth wheel hitches.
The SuperRail design handles most fifth wheel trailers on the road. It gives you a solid mounting platform that stays in your truck bed permanently.
Installation requires bolting brackets to your truck frame underneath the bed. The kit includes all necessary hardware.
PullRite makes these rails in the USA with quality steel construction. A five-year warranty backs the product.
