About This Product
The B&W RVK2405 is a mounting rail kit for trucks without factory fifth wheel prep. It provides the under-bed brackets and rails needed to install a B&W fifth wheel hitch rated up to 20,000 pounds.
This kit bolts to your truck frame underneath the bed. Once installed, you have industry-standard rails that accept B&W fifth wheel hitches and compatible equipment.
Installation requires working underneath your truck with basic hand tools. The kit includes all necessary brackets, rails, and hardware.
B&W makes these rails in the USA with heavy-duty steel construction.
