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 2016-2019 Chevrolet/GMC 2500 & 3500 Heavy Duty with OEM Puck System B&W Companion Slider 5th Wheel Hitch Kit For 2016-2019 GM Puck System RVK3770 (Part #BQVLRVK3770) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The Companion™ 20K Slider Hitch (Model 3770) is a 5th wheel hitch designed for 2016–2019 GM Puck System trucks. It has a maximum trailer weight rating of 20,000 lbs and a maximum trailer tongue weight rating of 5,000 lbs. Do not exceed these ratings or the tow and tongue ratings of your truck or trailer, as doing so may cause damage to towing components or loss of attachment between the trailer and truck.
The Companion™ 20K Slider Hitch (Model 3770, part number RVK3770) fits 2016–2019 GM Puck System trucks. Verify your truck has the GM Puck System attachment points before purchasing.
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 (RVB3770) includes: 1 Pivot Arm A, 1 Pivot Arm B, 8 × 1/2" Lock Washers, 8 × 1/2" × 2" Cap Screws, 1 Wire Torsion Spring, 1 Mounting Clip, 1 × 1/4" × 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 Companion Coupler with jaws, handle, safety pin, saddle, latch handle, latch pin, and saddle lock pin.
Remove all parts from packaging and familiarize yourself with all parts and tools using the parts list. Remove any debris and obstructions from the truck bed, including plastic caps over the attachment points. It may be necessary to remove plastic grommets from around the mounting points to fully seat the base. Verify all parts and hardware are present before beginning installation.
1. Remove latch pins from each side of the base and rotate the handles out. 2. 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. 3. Remove cotter pins from the four castle nuts. 4. Turn the latch handles back to their latched position to engage the cams with each attachment point. If a handle will not turn easily, loosen the castle nut until the cam will freely turn. 5. With the base firmly held down and each latch handle closed, replace the latch pins. When moving the slider base, the slider handle must be in the locked position and the carriage must be unable to slide. Grip the base by the end rail supports to lift it; lifting under the sheet metal covers may cause damage.
With the handles in the latched position, tighten the castle nut until snug to increase tension. 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. Do not set tension so that excessive force is required to close the handles, as this may result in property damage or personal injury. Verify latch tension each time the base is placed in a truck and periodically before towing.
The Companion hitch offers six different mounting locations for the pivot arms to allow flexibility in coupler height and distance from the cab. Choose a location so that your trailer will be as level as possible and have adequate turning clearance while in the towing position (with the slider in the forward position). The six positions range from the highest position (19") to the lowest position (17"), with middle position at 18", and allow positioning from closest to cab to farthest from cab with arms reversed. 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 to ensure proper clearance when towing.
Before towing, determine if there is clearance between your truck and trailer combination. 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, then 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. Check the clearance between the tailgate and trailer components such as the trailer tongue or pin box, as parts of the trailer may strike the tailgate when sliding the carriage rearward. Towing without adequate clearance may lead to property damage or serious injury.
1. Inspect the threaded blocks behind each set of arm mounting holes inside the carriage. If blocks shifted during shipping and threaded holes are not aligned with carriage holes, use a screwdriver to align them. The blocks should be positioned with the larger diameter hole openings against the inside face of the carriage and the corner chamfer on the end of the blocks pointing downward. 2. With the flat side of the pivot arms against the bolt plate in the carriage, install four 1/2" × 2" cap screws and four 1/2" lock washers. 3. Torque each cap screw to 110 ft-lbs. If a threaded block cannot be aligned through the carriage holes, the covers on top of the carriage can be removed with a 5/32" Allen wrench to access and reposition the blocks.
Each of the four 1/2" × 2" cap screws securing the pivot arms to the carriage must be torqued to 110 ft-lbs.
1. Locate the 1/4" cap screw and nut, wire torsion spring, and mounting clip. Pass the 1/4" cap screw through the mounting clip and the wire spring. Thread the 1/4" lock nut onto the 1/4" cap screw and tighten just enough that the spring will stay in place but will still be able to rotate around the bolt if needed. 2. Locate the flange on the driver side pivot arm that will be closest to the truck cab. The clip should be placed so that when the spring's coil is in line with the edge of the arm there will be 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. Lubricate the polyurethane bushings on top of the pivot arms with high grade lithium grease. 2. Place the coupler over the pivot arms. The saddle handles should be parallel with the slider base in the latched position. 3. 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.
1. Open the coupler by locating the two 3/8" × 1-1/4" button head cap screws and two 3/8" flanged lock nuts provided in the coupler bolt bag. Pull out the coupler arm and pin it with the safety locking pin near the base of the arm. 2. Using the button head cap screws and lock nuts, attach the coupler handle to the arm and tighten. 3. Pull out the coupler handle safety pin. Pulling the arm out away from the coupler creates a pinch point; use caution when installing the handle to avoid injury.
Adjust the resting angle of your 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 of the coupler so that it will tilt away from the cab when coupling. Once the spring's orientation is set, tighten the 1/4" nut.
1. Remove the safety pin from the coupler handle and open it. 2. Adjust the height of the 5th 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.
1. Lower the trailer landing gear and chock the trailer wheels. 2. Raise the trailer until the tongue weight is removed from the truck. 3. 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. 4. Use the safety pin to lock the handle in the open position. 5. 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 uninstall the Companion hitch, remove the saddle lock pins, grab the saddle handles, and lift to remove the coupler from the pivot arms. To remove the Companion 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.
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.
The maneuvering position allows you to move the trailer for parking maneuvers only, not for towing. To move from towing position to maneuvering position: 1. While the trailer is coupled, set the trailer brakes and/or chock the trailer wheels. 2. Pull the handle toward the rear of the truck to move it to the unlocked position. 3. Pull the truck forward slowly until the handle falls and is in the locked position. 4. Release the trailer brakes, un-chock the trailer, and maneuver the trailer as needed. Never exceed 5 mph (roughly walking speed) when in the maneuvering position. Use extreme caution when moving the truck and trailer in the maneuvering position. The slider mechanism should only be attempted on smooth flat terrain. Approximately 15%–25% of the trailer weight should be on the hitch in maneuvering position.
To move from maneuvering position to towing position: 1. Once the trailer is satisfactorily positioned, set the trailer brakes and/or chock the trailer wheels. 2. Pull the handle toward the rear of the truck to move it to the unlocked position. 3. Move the truck slowly in reverse until the handle falls and is in the locked position. 4. Release the trailer brakes and un-chock the trailer. The slider handle must be in the locked position before moving the tow vehicle; failure to do so may cause property damage or serious injury.
Use extreme caution when moving the truck and trailer in the maneuvering position. Never exceed 5 mph (roughly walking speed) when in the maneuvering position, as doing so may result in property damage, serious injury, or death. The maneuvering position is only intended for parking maneuvers and not for towing; using the slider in any other capacity could result in serious injury or death. Never hold on to the handle or force it in any direction while the truck is moving. Failure to stand clear of the handle when the slider is in operation could result in serious injury. The slider handle must be in the locked position before moving the tow vehicle; failure to do so may cause property damage or serious injury. Use of the slider mechanism should only be attempted while on smooth flat terrain.
Grease the saddle through the grease zerk approximately every six months with multi-purpose grease to allow the coupler to pivot freely. Grease the jaws with multi-purpose automotive type chassis grease. Lubricate the top surface of the coupler with multi-purpose automotive type chassis grease or use a nylon lube plate to provide a lubricated surface. Lubricate the polyurethane bushings on top of pivot arms with high grade lithium grease as needed. 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.
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.
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, etc.). 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.
No. Do not use the Companion 5th wheel hitch with any device that changes the location of the king pin pivot point, including a Reese Sidewinder® or Reese Revolution®. The king pin on your trailer must rotate in the jaws of the Companion coupler. Preventing the king pin from rotating within the jaws of the Companion coupler with a wedge or any other device could result in property damage, serious injury, or death.
No. Do not modify this product in any manner. Doing so could alter its integrity and lead to a loss of attachment between the trailer and the tow vehicle.
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 at www.NATM.com and your trailer manufacturer's owner's manual. Components of the hitch are heavy and cumbersome to handle. Use proper lifting techniques when moving and handling parts.
The Companion™ 20K Slider Hitch (Model 3770) fits 2016–2019 GM Puck System trucks only. Verify your truck has the GM Puck System attachment points before purchasing.
Maximum trailer weight: 20,000 lbs. Maximum trailer tongue weight: 5,000 lbs. Do not exceed these ratings or your truck and trailer manufacturer's ratings.
You need: a torque wrench capable of 110 ft-lbs, 3/4" socket, 7/16" socket, 9/16" socket or wrench, 7/32" Allen wrench, needle-nose pliers, and a hammer.
The four 1/2" × 2" cap screws securing the pivot arms must be torqued to 110 ft-lbs.
No drilling is required. The hitch uses the existing GM Puck System attachment points on 2016–2019 GM trucks.
Never exceed 5 mph (roughly walking speed) when in the maneuvering position. Exceeding this speed may result in property damage, serious injury, or death.
Grease the saddle through the grease zerk approximately every six months with multi-purpose grease. Lubricate the polyurethane bushings on top of pivot arms with high grade lithium grease as needed. Grease the jaws with multi-purpose automotive type chassis grease.
Perform a visual inspection before each tow: verify all pinned connections are secure, check that all bolted connections are at correct torque, and inspect for cracks or damage. Do not tow if cracks or damage outside of normal wear are found.
Loosen the castle nut until the cam will freely turn and engage the attachment point. Once the cam can turn freely, re-tighten the castle nut to the proper tension following the adjustment procedure: rotate the handle open and closed, tighten slightly, and repeat until you feel the cam engage while closing the handle.
If the jaws do not open when you rotate the coupler handle to the open position, readjusting the landing gear may relieve pressure and allow them to open. Raise the trailer landing gear to remove tongue weight from the truck, which should allow the jaws to open.
Try using a screwdriver or similar tool to align the blocks through the carriage holes. If a block cannot be aligned this way, the covers on top of the carriage can be removed with a 5/32" Allen wrench to access the blocks directly. Reposition the blocks so the larger diameter hole openings are against the inside face of the carriage and the corner chamfer points downward. Reinstall and tighten the cover screws.
Pull the handle toward the rear of the truck to move it to the unlocked position. Move the truck slowly in reverse until the handle falls and is in the locked position. If the handle does not lock, ensure you are on smooth flat terrain and that the truck is moving slowly in reverse. The slider mechanism should only be attempted on smooth flat terrain.
