Features & Benefits
Built for Serious Fifth Wheel Towing
The Companion OEM 20K is engineered for truck owners who tow substantial fifth wheel trailers and require dependable performance under demanding conditions.
With ratings of:
- 20,000 lbs Gross Trailer Weight (GTW)
- 5,000 lbs Vertical Load Capacity
This hitch is capable of handling many of today's larger RVs, toy haulers, horse trailers, and recreational trailers with confidence.
The heavy-duty steel construction provides long-term durability while maintaining the strength necessary for years of towing service.
Precision Dual-Jaw Coupler System
At the core of the Companion's performance is B&W's renowned dual-jaw locking mechanism.
Unlike traditional slide-bar hitch designs, the Companion uses two precision-machined 1" thick steel jaws that completely surround the trailer king pin.
Benefits include:
- Full 360-degree king pin contact
- Reduced trailer movement
- Less chucking
- Minimal rattling
- Improved towing stability
This secure connection helps create a smoother, quieter towing experience while increasing driver confidence behind the wheel.
Polyurethane Bushings for a Smoother Ride
Road imperfections and trailer movement can create vibration and shock that transfer through the hitch.
To combat this, B&W incorporates durable polyurethane bushings between the hitch head and pivot arms.
Advantages include:
- Reduced vibration transfer
- Improved ride quality
- Less road shock
- Reduced metal-on-metal contact
- Quieter towing operation
These bushings play a major role in the Companion's reputation for delivering a refined towing experience.
Fully Articulating Hitch Head
The Companion's hitch head pivots:
- Front-to-back
- Side-to-side
This allows the hitch to move naturally with the trailer during turns, uneven terrain, and campground maneuvering.
Benefits include:
- Easier hitching and unhitching
- Better trailer tracking
- Reduced stress on hitch components
- Improved towing comfort
- Enhanced control over rough terrain
The articulating design helps maintain a secure connection while accommodating changing road conditions.
Cam-Action Release Handle
Unhitching a trailer can be difficult when pressure exists between the truck and trailer.
The Companion's cam-action release handle is designed to minimize binding and simplify uncoupling.
Benefits include:
- Easier release on uneven ground
- Reduced jaw binding
- Smooth operation under load
- Improved campsite convenience
Simply move the handle to the open position and pull forward slightly to allow the jaws to release naturally.
For added security, the handle can be secured using:
- Included retaining pin and clip
- Optional padlock with a 5/16" shackle
Adjustable Height and Positioning
Proper trailer leveling is critical for safe towing and optimal handling.
The Companion OEM features adjustable pivot arms that allow owners to customize their setup.
Height Adjustment Range
Fore/Aft Positioning
The pivot arms can be mounted in different positions to help optimize:
- Trailer level
- Bed rail clearance
- Weight distribution
- Cab-to-trailer spacing
These adjustments allow the hitch to accommodate a variety of truck and trailer combinations.
