B&W Trailer Hitches is an American manufacturer known for durable, innovative towing products, including gooseneck hitches, fifth-wheel hitches, receiver hitches, and ball mounts. Built in Kansas by employee-owners, B&W products are engineered for dependable performance, easy installation, and long-lasting quality.
B&W Trailer Hitches is an American manufacturer known for building innovative, dependable towing products designed to make hitching easier and towing more comfortable. The company began in 1987 in Humboldt, Kansas, when founders Roger Baker and Joe Works combined their fabrication experience to build custom truck beds and solve common problems faced by truck owners.
B&W changed the gooseneck hitch industry with the introduction of the Turnoverball Gooseneck Hitch. Its under-bed mounting system and reversible hitch ball allowed truck owners to quickly store the ball beneath the bed, leaving a clean and unobstructed surface when the hitch was not in use. B&W later applied the same practical approach to the Companion Fifth Wheel Hitch, creating a removable fifth-wheel hitch engineered for a quiet, smooth, and secure towing experience.
Today, B&W manufactures gooseneck hitches, fifth-wheel hitches, receiver hitches, ball mounts, and towing accessories at its nearly 600,000-square-foot facility. The company is owned by approximately 500 employee-owners who remain committed to American manufacturing, trusted materials, skilled craftsmanship, and long-lasting product quality.
Whether you are towing a work trailer, livestock trailer, camper, or fifth wheel, B&W Trailer Hitches offers thoughtfully engineered towing equipment built to perform mile after mile.

The Companion 25K Hitch (Model 3705) is a fifth-wheel hitch for 2016–2019 GM Puck System trucks. It is rated for a maximum trailer weight of 25,000 lbs and a maximum trailer tongue weight of 6,250 lbs. Do not exceed these ratings or the tow and tongue ratings of your truck, trailer, or coupler, as exceeding them may cause damage to towing components or loss of attachment between the trailer and truck.
The Companion 25K Hitch (Model 3705) fits 2016–2019 GM Puck System trucks.
Installation requires a large torque wrench capable of measuring 110 ft-lbs, a 3/4" socket, a 7/16" socket, a 9/16" socket or wrench, a 7/32" Allen wrench, a pair of needle-nose pliers, and a hammer.
The Base Bolt Bag (RVB3705) includes: 1 Pivot Arm A, 1 Pivot Arm B, 8 1/2" x 2" Hex Cap Screws, 8 1/2" Lock Washers, 4 Threaded Blocks, 1 Wire Torsion Spring, 1 Mounting Clip, 1 1/4" x 1/2" Cap Screw, and 1 1/4" Lock Nut. The Coupler Bolt Bag (RVC3006) includes 2 3/8" Button Head Cap Screws and 2 3/8" Lock Nuts. The hitch also includes a coupler, base, saddle, latch handle, coupler handle, safety pin, locking pins, and saddle handle.
Remove all parts from packaging and familiarize yourself with all parts and tools. Verify that all parts and hardware are present using the parts list. Remove any debris and obstructions from the truck bed, including plastic caps over attachment points. It may be necessary to remove plastic grommets from around mounting points to fully seat the base down to the truck.
The pivot arms can be mounted in one of six different locations (shown in Table A1) to allow flexibility in coupler height (vertical adjustment) and distance from the cab (horizontal adjustment). Choose a location so that your trailer will be as level as possible and have adequate turning clearance while towing. The three vertical positions are at 16-3/4", 17-3/4", and 18-3/4". The two horizontal positions are 2" behind the axle (farthest from cab) and over the axle (closest to cab).
The threaded blocks have threaded holes on one side and smooth bored holes on the other side. It is critical that the side with the smooth holes is flat against the bolt plate when installed. Installing the threaded blocks backward will not allow the pivot arms to be fully tightened and could lead to hitch failure. Before coupling the hitch, verify that none of the 1/2" x 2" bolts are loose and the pivot arms are securely attached to the bolt plate.
After all the 1/2" cap screws are started through the pivot arms and threaded blocks, torque each bolt to 110 ft-lbs.
Measure from the center of the coupler to the cab of the truck and from the king pin or pivot point of the trailer to the furthest forward corner of the trailer. Compare these measurements to ensure proper clearance when towing. Also inspect the clearance between the bed sides and the underside of the front of the trailer to ensure there is room for the pitch and roll of the trailer while towing. Towing without adequate clearance may lead to property damage or serious injury.
1. Locate the 1/4" cap screw, 1/4" lock nut, wire torsion spring, and mounting clip. Pass the 1/4" cap screw through the mounting clip and wire spring. Thread the 1/4" lock nut onto the cap screw and tighten just enough that the spring stays in place but can still rotate around the bolt. 2. Locate the flange closest to the truck cab on the driver side pivot arm. Place the clip so that when the spring's coil is in line with the edge of the arm, there is 1/2" of clearance between the bottom of the polyurethane bushing and the top of the spring. Drive the clip securely onto the flange with a hammer.
1. Remove the latch pins from each side of the base and rotate the handles out. Position the base over the attachment points and carefully lower it until the latch cams pass through the floor and the base rests flat against the top of the attachment points. 2. Remove the cotter pins from each of the four castle nuts. Engage the cams with each attachment point by turning the latch handles back to their latched position. If a handle will not turn easily, loosen the castle nut until the cam will freely turn and engage the attachment point.
With the handles in the latched position, tighten the castle nut until snug to increase tension on the latch. Rotate the latch handle open and closed. Tighten the castle nut slightly and rotate the handle open and closed again. Repeat until you feel the cam engage the attachment point while closing the handle. The handle is set at proper tension when there is friction between the cam and attachment point but the handle can still be closed by hand without bumping, tapping, or otherwise forcing it closed. Setting latch handle tension so that excessive force is required to close the handles may result in property damage or personal injury. Verify latch tension each time the base is placed in a truck and periodically before towing.
1. Pull out the coupler arm and pin it with the safety locking pin near the base of the arm. 2. Locate the two 3/8" x 1-1/4" button head cap screws and two 3/8" flanged lock nuts from the bolt bag. Using these fasteners, attach the coupler handle to the arm and tighten. Pull out the coupler handle safety pin. Use caution when installing the handle to avoid pinch point injury.
Lubricate the polyurethane bushings on top of the pivot arms with high-grade lithium grease. Place the coupler over the pivot arms (the saddle handles should be parallel with the base in the latched position). Place the saddle lock pins through the saddle, then insert the hairpins through the holes in the end of the saddle lock pins to secure the coupler to the pivot arms.
Adjust the resting angle of the coupler plate by rotating the spring on the driver side pivot arm. Pulling the top of the spring away from the cab will increase the angle of the coupler plate. Set the angle so that the coupler will tilt away from the cab when coupling. Tighten the 1/4" nut once the spring's orientation is set.
1. Remove the safety pin from the coupler handle and open it. 2. Adjust the height of the fifth-wheel trailer so that the king pin plate is slightly lower than the top of the coupler. 3. Back the truck toward the trailer, centering the trailer's king pin in the coupler, until the king pin engages the jaws. 4. Close the coupler handle and insert the safety pin through the handle and the coupler. 5. Connect the brake and lighting systems before towing.
The pull test verifies that the trailer is correctly attached before towing. Ensure the truck is stationary with the emergency brake engaged and the tailgate down, trailer wheels chocked, and landing gear down supporting the trailer's weight. Confirm no one is between the truck and trailer. Release the emergency brake and engage the trailer brakes. Gently attempt to pull the trailer forward with the truck. When properly connected, the trailer will prevent the truck from moving. If the truck and trailer are not correctly attached, the trailer will separate from the truck.
Some pin boxes remove the pivot point between a trailer and coupler and must not be used. For example, PullRite SuperGlide capture plates remove the pivot point and should not be used. Pin boxes with a wedge that relocates the pivot point, such as Reese Sidewinder or Reese Revolution, may be used. Towing a trailer without a functioning pivot point between the hitch and trailer will cause significant damage to the hitch, which may lead to serious injury or death.
Additional caution must be used when towing a wedge car trailer. Towing stability greatly depends on keeping the center of gravity as low as possible. Load heavy cars over the axles. Never tow with a single car on the front of the trailer. When towing a wedge car trailer, never exceed speeds that are reasonable for the roadway conditions (e.g. turns, going around a curve). Failure to account for proper trailer center of gravity and speeds that are reasonable for the roadway conditions may cause damage to the truck, trailer, towing components, and loss of attachment between the truck and trailer.
A visual inspection of the hitch should be performed before each time you tow. Regularly check that all pinned connections are secure and that all bolted connections are at the correct torque specification. Check for cracks or damage to the hitch. Do not tow with the hitch if cracks or damage outside of normal wear is found. Towing with a hitch that has cracks or damage could result in damage to the tow vehicle, trailer, towing components, or loss of attachment between the tow vehicle and trailer.
Grease the saddle through the grease zerk approximately every six months with multi-purpose grease. This allows the coupler to pivot freely. Also grease the jaws with multi-purpose automotive type chassis grease. When installing the coupler, lubricate the polyurethane bushings on top of the pivot arms with high-grade lithium grease.
Base latch handle tension and all bolted connections should be checked regularly. The latches must have the proper resistance when rotating, and bolts must have proper torque. Always perform a visual inspection before towing. Verify latch tension each time the Companion base is placed in a truck and periodically before towing.
Lower the landing gear and chock the trailer wheels. Raise the trailer until the tongue weight is removed from the truck. Unpin the coupler handle and rotate it to the open position to unlatch the jaws. If the jaws do not open, readjusting the landing gear may relieve pressure and allow them to open. Use the safety pin to lock the handle in the open position. When you are sure that the landing gear will support the trailer, move the truck forward to release the jaws from the king pin. The jaws will always open when the pressure of the trailer is taken off the coupler as the truck pulls away.
To remove the coupler, remove the saddle lock pins, grab the saddle handles, and lift to remove the coupler from the pivot arms. To remove the base, remove the latch pins from each side of the base and turn the handles. Carefully lift and position the base out of the attachment points.
Approximately 15%–25% of the trailer weight should be on the hitch.
The height of the king pin box and pivot arms should be adjusted so that the trailer is approximately level for towing. Allow adequate clearance between the bed side and the underside of the front of the trailer for pitch and roll of the trailer.
Without proper knowledge, towing can be a dangerous activity. Understand all the risks involved with towing before proceeding. For information on towing safety, see "The Trailer Handbook: A guide to Understanding Trailer and Towing Safety" from the National Association of Trailer Manufacturers (www.NATM.com) and your trailer manufacturer's owner's manual. Do not modify this product in any manner, as doing so could alter its integrity and lead to a loss of attachment between the trailer and the tow vehicle.
The Companion 25K Hitch (Model 3705) fits 2016–2019 GM Puck System trucks only.
You need a large torque wrench capable of 110 ft-lbs, 3/4" and 7/16" sockets, 9/16" socket or wrench, 7/32" Allen wrench, needle-nose pliers, and a hammer.
No drilling is required. The hitch uses the existing GM Puck System attachment points on the truck bed.
Torque all 1/2" x 2" cap screws to 110 ft-lbs.
Maximum trailer weight is 25,000 lbs and maximum trailer tongue weight is 6,250 lbs. Do not exceed these ratings or the tow and tongue ratings of your truck or trailer.
Yes. Remove any debris and obstructions from the truck bed, including plastic caps over attachment points and plastic grommets around mounting points, to fully seat the base.
Perform a visual inspection before each towing trip. Check that all pinned and bolted connections are secure and at correct torque. Check for cracks or damage. Do not tow if damage outside of normal wear is found.
The smooth bored holes must face the bolt plate. Installing them backward will prevent full tightening and could cause hitch failure.
Do not use pin boxes that remove the pivot point, such as PullRite SuperGlide capture plates. Pin boxes with a wedge that relocates the pivot point, such as Reese Sidewinder or Reese Revolution, may be used.
Loosen the castle nut until the cam will freely turn and engage the attachment point. Then readjust the tension by tightening the castle nut slightly and rotating the handle open and closed repeatedly until proper tension is achieved (friction between cam and attachment point, but handle closes by hand without forcing).
Readjusting the landing gear may relieve pressure and allow the jaws to open. Raise the trailer until the tongue weight is removed from the truck, then try opening the jaws again. If the jaws still do not open, further adjustment of the landing gear may be needed.
This indicates the truck and trailer are not correctly attached. The trailer will separate from the truck. Do not tow. Disconnect the trailer and verify that the coupler handle is fully closed, the safety pin is inserted through the handle and coupler, and the king pin is fully engaged in the coupler jaws. Perform the pull test again.
