Overview of the B&W Companion OEM Fifth Wheel Hitch
The B&W Companion OEM fifth wheel hitch is engineered for ease of installation and removal, thanks to its innovative puck-based mounting system. This design eliminates traditional hitch rails, allowing for a flat and unobstructed truck bed when the hitch is not in use. The hitch is composed of two primary components: the hitch base and the coupler (also referred to as the head). Together, these components weigh approximately 206 pounds (131 lbs. for the base and 75 lbs. for the coupler), making it a two-person job for installation and removal.
The hitch is rated for a maximum towing capacity of 25,000 pounds, making it suitable for a wide range of fifth wheel trailers. It features a four-legged base with quarter-turn locking mechanisms that secure into the truck's five pucks—four for the hitch and one for gooseneck use. The system is designed for Ram, Ford, and Chevrolet trucks, though the exact placement and orientation of the pucks may vary by model.
Key Components and Tools Required
To assemble and install the B&W Companion OEM fifth wheel hitch, the following components and tools are required:
- Hitch Base: The triangular base that mounts to the truck bed using the puck system.
- Hitch Coupler (Head): The top component that connects to the trailer.
- Pivot Arms: Four triangular arms that support the coupler and allow for height adjustment.
- Lock Washers and Bolts: Used to secure the pivot arms to the hitch base.
- Saddle Handles and Lock Pin: Used to secure the coupler to the base.
Tools
- 3/4″ socket

- 15/16″ socket or 15/16″ wrench
- 7/32″ allen wrench
- Needle-nose pliers
- Small hammer
- Lubricants: Lucas Oil X-tra Heavy Duty Grease and CRC Silicone Spray (optional)
The installation instructions typically come with the hitch, and a digital version is also available on the manufacturer’s website. Additionally, the hitch base includes a sticker with mounting instructions for the two main components.
Step-by-Step Installation Process
1. Preparing the Truck and Components
Before beginning the installation, ensure that the truck is equipped with the appropriate fifth wheel or gooseneck towing prep package. This includes the five pucks installed in the truck bed. The pucks are typically arranged in a rectangular pattern with one puck in the center for gooseneck use.
Lay out all the components from the B&W Companion OEM fifth wheel hitch on a clean, flat surface. This allows for a clear view of the parts and ensures nothing is misplaced during the installation process.
2. Assembling the Hitch Base
The first step involves assembling the hitch base. This includes attaching the four pivot arms to the base using the provided bolts and lock washers. The orientation of the pivot arms is critical and depends on the truck model. For example, in the case of the Ram 3500 dually long bed, the shallower slope of the pivot arms should face the cab of the truck. This ensures proper alignment with the trailer and minimizes side clearance issues.
There are five possible hole positions on each pivot arm, allowing for height adjustment. This can be used to fine-tune the gap between the trailer overhang and the truck bed. A middle setting is often a good starting point, but adjustments can be made as needed.
Each bolt and lock washer is inserted into the threaded block on the back side of the pivot arm. Tighten the bolts using a 3/4″ socket and a 15/16″ wrench to secure the arms in place.
3. Adjusting the Cap Screws and Latch Handle
Once the pivot arms are attached, the next step is to adjust the cap screws on the pilot assemblies of each foot. This is done by loosening and tightening the screws to ensure the base fits snugly into the truck’s pucks.
After the base is in place, the tension in the latch handle is adjusted by modifying the height of the castle nut. This involves removing the cotter pin using needle-nose pliers, adjusting the nut to the desired position, and reinstalling the pin. The end of the pin is then bent to secure it in place.
These adjustments are one-time settings that allow for easy opening and closing of the latch handle in the future.
4. Mounting the Hitch Base in the Truck Bed
With the base fully assembled and adjusted, it is time to mount it in the truck bed. Using the puck system, each foot of the base is inserted into the corresponding puck. A quarter-turn locking mechanism on each foot secures the hitch in place. This system allows for quick and easy installation and removal.
Once the base is mounted, the latch handle can be tested to ensure it operates smoothly. If any fine-tuning is needed, the four pucks and four legs can be adjusted to ensure a perfect fit.
5. Installing the Hitch Coupler
The final step is to attach the hitch coupler (head) to the base. This is done by lowering the coupler onto the base and pushing the saddle handles down until the saddle lock pin is engaged. The coupler is now securely attached and ready for use.
Before connecting to a trailer, it is recommended to clean the hitch plate on the trailer and apply a lubricant such as CRC Silicone Spray to both the trailer hitch plate and the coupler plate. This helps reduce friction and ensures smooth operation.
6. Final Adjustments and Testing
After the hitch is fully assembled, it is important to test the system. This includes opening and closing the latch handle, adjusting the pivot arms if necessary, and ensuring that the coupler is securely attached. Any additional lubrication or adjustments can be made at this stage.
One user noted that they adjusted the pivot arms down one notch after initial installation, which improved the fit for their specific truck and trailer combination. These adjustments are relatively simple and can be made in the future if needed.
User Experience and Practical Considerations
Several users have shared their experiences with installing and using the B&W Companion OEM fifth wheel hitch. One user reported that the installation could be completed in approximately one hour as a DIY project, compared to the two-hour installation typically performed by a dealership. This is a significant time and cost savings for many RV owners.
The installation was split into two stages for one user: first, assembling the hitch in a friend’s garage, and second, mounting it in the truck bed after receiving the vehicle. The first stage took 40 minutes, and the second took 20 minutes for fine-tuning. Future installations, according to the user, will take only a few minutes due to the simplicity of the puck system.
The use of a hydraulic lift table for moving the hitch in and out of the truck bed was also mentioned as a helpful tool for users without strong assistance or garage space. This can be especially useful for those who frequently remove the hitch to accommodate cargo or other uses of the truck bed.
One user highlighted the ease of removal and reinstallation, emphasizing that the truck bed remains completely flat and free of obstacles when the hitch is not in use. This is a key advantage of the puck-based system over traditional rail-mounted hitches.
Maintenance and Safety Considerations
To maintain optimal performance of the B&W Companion OEM fifth wheel hitch, regular lubrication of the hitch jaws and moving parts is recommended. Lucas Oil X-tra Heavy Duty Grease or a similar automotive chassis grease should be applied to the inside of the hitch jaws to reduce friction and wear. This should be done periodically, especially after long hauls or in harsh weather conditions.
Lubrication of the trailer hitch plate and coupler plate with CRC Silicone Spray is also advised before each connection to the trailer. This helps prevent corrosion and ensures smooth engagement.
Safety is a critical consideration when using any fifth wheel hitch. Users are advised to inspect the hitch before each use, checking for any signs of wear, damage, or loose components. The cotter pin on the castle nut should be inspected to ensure it is properly secured. Additionally, the latch handle should be tested to confirm it operates smoothly and locks securely.
