What exactly is the Quick Coupler?
The Quick Coupler™ is a self-aligning, automatic-latching, cable-release gooseneck safety coupler built to replace the standard coupler on horse, livestock, cargo, racecar-hauler, and flatbed commercial gooseneck trailers. Its defining feature is a 5 1/2-inch cone-shaped capture area that funnels the hitch ball into position, so the trailer drops onto the ball and latches on its own. It is engineered for the industry-standard 2 5/16" ball, and the original QCR4 8K listing carries a gross tongue weight of 8,000 lbs.
The Quick Coupler™ is produced by Trailer Gear, Inc., based in Carlisle, Pennsylvania, and now sold online at quickcoupler.com. Every coupler is Made in the USA and backed by a limited lifetime warranty. You can reach the company directly at (724) 216-3208 or by.
QCR4 S 4-inch square-tube Quick Coupler gooseneck hitch
How does the self-latching hookup work?
Instead of inching the truck into a precise spot and crawling underneath to throw a latch, you back up roughly, lower the gooseneck, and the conical capture area guides the ball into the coupler. The coupler latches automatically the moment it seats, eliminating repeated hookup attempts and the need to get under the trailer. A hold-open tab and an integrated release cable let you drop the latch from a standing position when it is time to unhook.
The current lineup spans round and square gooseneck receivers. Round-tube models include the QCR-10K at $519.00, the QCR-12K at $549.00, and the QCR 5" OS at $569.00. Square-tube models include the QCS 4" Square at $499.00 and the QCS 4.5" Square at $529.00. The QCR4 S square coupler is rated for 12,000 lbs gross tongue weight and 30,000 lbs gross trailer weight, and each coupler ships complete with the Cable Release Kit.
Is installation a bolt-on or a weld-on job?
The Quick Coupler is a bolt-on replacement that needs no welding. Using only a wrench, a pencil, and a drill, you loosen the two jam nuts and two set screws to remove the original coupler, slide the new Quick Coupler into the receiver tube, orient the locking arm to the driver's side, set the height, and re-secure the set screws and jam nuts. You then route the release cable with the provided guides, pulley, hanger, and self-tapping screws, and grease the rear grease zerk. It fits 4" round or 4-4.5" square adjustable coupler receivers.
How do you order the Quick Coupler?
Couplers are sold directly through quickcoupler.com, where you select your receiver type and size and add the matching Cable Release Kit. Shipping and handling runs $46.00, with a square coupler shipping at roughly 37 lbs and a round model around 44 lbs. For sizing questions or to confirm fitment for your gooseneck, call Trailer Gear, Inc. at (724) 216-3208 or email before you buy.

What is the Quick Coupler™ by Trailer Gear, Inc.?
It is a rugged, heavy-duty gooseneck safety coupler that replaces the standard coupler on your trailer. It self-aligns onto the hitch ball and latches automatically, making hookup faster, safer, and easier than wrestling with a conventional gooseneck coupler. It is designed for horse, livestock, cargo, racecar-hauler, and flatbed commercial gooseneck trailers.
How does the automatic self-latching feature work?
The coupler has a 5 1/2-inch cone-shaped capture area that funnels the hitch ball into the correct position as you lower the gooseneck. When the ball seats, the coupler latches on its own. There is no need to back up perfectly or crawl under the trailer to throw a latch by hand.
What is the gross tongue weight rating of the QCR4 8K?
The original QCR4 8K listing is rated at 8,000 lbs gross tongue weight. The company's current square-tube QCR4 S model is rated at 12,000 lbs gross tongue weight and 30,000 lbs gross trailer weight, so there are options across a range of load capacities.
What ball size does the Quick Coupler use?
All Quick Coupler models are built for the industry-standard 2 5/16-inch ball. This is the common gooseneck ball size, so it works with standard gooseneck ball setups in most trucks and beds.
Is the Quick Coupler made in the USA?
Yes. The Quick Coupler is Made in the USA and is backed by a limited lifetime warranty, reflecting Trailer Gear's confidence in the build quality of the product.
Does installation require welding?
No. The Quick Coupler is a bolt-on replacement that needs no welding. You only need a wrench, a pencil, and a drill. You loosen the existing jam nuts and set screws, remove the original coupler, slide the Quick Coupler into the receiver tube, set the height, and re-secure it.
What receiver sizes does it fit?
It is designed for 4-inch round or 4 to 4.5-inch square adjustable coupler receivers. The lineup includes round-tube models, square-tube models in 4-inch and 4.5-inch, and an oversized 5-inch round option, so there is a fit for most common gooseneck receiver tubes.
What models and prices are available?
Current models include the QCR-10K at $519.00, the QCR-12K at $549.00, the QCR 5" OS at $569.00, the QCS 4" Square at $499.00, and the QCS 4.5" Square at $529.00. The original QCR4 8K is listed at $499.00. Each coupler ships complete with the Cable Release Kit.
What is included in the box?
Each Quick Coupler ships as a complete assembly with the Cable Release Kit, which includes the cable, routing guides, a pulley, a hanger, self-tapping screws, and a hold-open tab. This means you receive everything needed to install the coupler and its release mechanism.
How do I install the release cable kit?
After the coupler body is bolted into the receiver tube, you route the release cable using the provided guides, pulley, and hanger, fastening them with the included self-tapping screws. You also install the hold-open tab, then grease the unit through the rear grease zerk. This lets you release the latch from a standing position.
Why is the Quick Coupler safer than a standard coupler?
Because it self-aligns and latches automatically, it removes two of the riskiest parts of hooking up: spotting the ball perfectly and crawling under the trailer to lock the latch. The cone-shaped capture area reduces missed connections, and safety chains are still recommended for backup security.
What kinds of trailers is it designed for?
The Quick Coupler is built for gooseneck-style trailers including horse trailers, livestock trailers, cargo trailers, racecar haulers, and flatbed commercial gooseneck trailers. Its heavy-duty construction targets owners who hook and unhook frequently and want a faster, safer routine.
How much does shipping cost and how heavy is the coupler?
Shipping and handling is $46.00. A square-tube coupler ships at roughly 37 lbs and a round-tube model around 44 lbs, so it is a substantial, heavy-duty steel unit rather than a lightweight accessory.
How do I choose between a round and a square coupler?
Match the coupler to your trailer's existing gooseneck receiver tube. If your gooseneck uses a 4-inch round adjustable tube, choose a round model such as the QCR; if it uses a 4-inch or 4.5-inch square tube, choose the QCS square model. When in doubt, call the company to confirm fitment before ordering.
Which way should the locking arm face during installation?
During installation you orient the locking arm so the release is positioned for the driver's side, then adjust the coupler height before tightening the set screws and jam nuts. Correct orientation ensures the release cable routes cleanly and the latch is easy to operate from a standing position.
How do I order or get fitment help?
You can order directly from the company's website at quickcoupler.com (the trailergear.com address now redirects there). For sizing questions or to confirm the right model for your gooseneck, call Trailer Gear, Inc. at (724) 216-3208 or email [email protected].
Does the Quick Coupler need maintenance?
Routine maintenance is minimal. The coupler includes a grease zerk at the rear so you can periodically lubricate the moving parts, which keeps the self-latching mechanism operating smoothly. Keeping the capture area and latch clean and greased helps ensure reliable, consistent hookups over time.
