  • B and W

Drop in a Companion and skip the rails. This custom underbed kit gives you a clean fifth-wheel setup that clears the bed when you're done. Flip the ball, pull the hitch, and haul whatevers next - no rails, no drama, just a solid setup that works.


Highlights

  • Clean Bed When You're Not Towing: Flip the ball and remove your Companion for full bed access.
  • Square Post Holds Tight: Companion locks into the square base to prevent twisting or shifting.
  • Heavy-Duty Capacity: Gooseneck supports up to 30,000 lbs GTW and 7,500 lbs vertical load.
  • Easy-Access Latch Handle: Unlocks at the driver-side wheel well - no crawling in the bed.
  • Flush Chain Loops for Gooseneck Use: Spring-loaded loops sit low when not in use.

Features to know about

Tow a Fifth Wheel - Then Clear the Bed: Underbed Mounting with Flip-Over Ball

This underbed kit works with your Companion fifth-wheel hitch (BWRVK3500 or BWRVK3400) to deliver clean towing with no rails left behind. When it's time to unload gear, just pull the handle, flip the ball, and reclaim your full bed.

No Rails, No Compromises: Custom Fit That Doesn't Take Over the Truck

Unlike traditional fifth-wheel installs that leave rails in the way, this one stays hidden under the bed. There's nothing left to step over, stack on top of, or work around when your Companion is out.

Drop-In Confidence Every Time: Square Post Keeps the Companion Locked In

The Companion's square post drops into the base and locks down firm. It won't rotate under load or bind when you're trying to remove it. Drop it in, line it up, and you're hitched.

Supports Your Fifth-Wheel Setup with Confidence: Built for the Companion Hitch

B&W Companion Installed in Turnoverball Gooseneck Hitch

Whether you're using the fixed Companion (BWRVK3500) or the sliding version (BWRVK3400), this underbed kit provides the sturdy foundation you need. It's built to pair seamlessly, so your Companion can do the heavy lifting without interference.

No Climbing to Unhitch: Driver-Side Handle for Easy Ball Release

Whether you're flipping the ball or pulling the Companion out, the release handle is easy to reach right from the wheel well. Twist to lock it open, flip the ball, and you're done.

Gooseneck-Ready If You Ever Need It: Flush Chain Loops Built In

B&W Turnoverball Gooseneck Hitch

Still want gooseneck capability someday? You've got it. Spring-loaded chain loops sit flush when you're not using them. Clean setup - designed and made in the USA.
