The Curt A20 5th Wheel Trailer Hitch is rated for 20,000 lbs gross towing weight and 5,000 lbs tongue weight, making it a solid choice for big fifth wheels and long hauls. The heavy-duty steel construction and carbide powder coat finish give it strength and lasting protection. It’s a hitch that feels sturdy every time you drop the trailer on it—steady and dependable mile after mile.
The interlocking two-piece jaw wraps fully around the king pin for 360-degree contact, keeping movement to a minimum and giving you a quieter, more secure connection than slide-bar models. You can easily see what the jaws are doing thanks to Curt’s three-point color indicator system—red for uncoupled, yellow for ready to couple, and green when you’re locked in and ready to tow. It’s simple feedback you can check at a glance before pulling away.


This hitch’s torsion head self-aligns for easy hookup while controlling movement for a stable, quiet ride. It helps suppress road shock so you feel less bumping and hear fewer clanks as you tow. The built-in cushioning lets the trailer move naturally with the truck over uneven roads, keeping everything more comfortable over long stretches.
When it’s time to free up your truck bed, the fast one-pin head removal makes it easy for one person to lift off the hitch head without extra tools. Two built-in zerk fittings keep lubrication simple so everything moves smoothly trip after trip. The included plastic lube plate helps the king pin glide right into position during hookup, saving wear on both the hitch and trailer over time.
Getting your trailer level is straightforward with the four-inch height adjustment range built into the Curt A20. Just set it between 13" and 17" to match your setup. Once dialed in, the hitch gives you that balanced stance that makes towing feel right—steady down the highway and predictable when backing into tight spots.

Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at the CURT Custom Fifth Wheel Bracket Kit for the Chevrolet and GMC trucks. Now, this is a custom fit part. It is designed to fit the 1999 to 2010 Chevrolet Silverado and GMC Sierra 1500, 2500 and 3500 models, with either the six and a half foot bed or the eight foot bed. And on a custom fit part like this, I do like to recommend for you to go to our website, use the fit guide, put in your year and model vehicle. That'll show you if this will work for your application.
Now these brackets right here, they are designed to mount beneath your truck bed to provide the attachment point for your fifth wheel rails. Now those fifth wheel rails, we do sell separately on our website. They go by part number C16104 or C16204. And just give you an idea what those rails look like, they come in a set of two, and again, they'll attach to these mounting brackets on your vehicle. This provides a custom fit by mounting to the existing holes in your vehicle's frame.
That will minimize the amount of drilling that's required to install these, and it'll cut the installation time in half when compared with universal bracket kits. If you notice, it does include all the necessary hardware to install it. It does even come with this nice extra bracket for relocation of the electrical box. And it comes with a nice set of instructions with pictures that'll describe how these parts install. The finish on these brackets is a nice black powder coat finish to resist corrosion.
And these will work with the BMW, CURT, Draw-Tite, and Husky above bed fifth wheel trailer hitches. But that should do it for the review on the CURT Custom Fifth Wheel Bracket Kit for the Chevrolet and GMC trucks..

Sorry to hear about the damage and difficulties, Jeff. The handle will get easier to actuate with use as they can be on the stiff side when new. I don't recommend beating it with anything as that will probably damage the mechanism. So don't do that. Are those B&W rails in your bed? And what do you carry in your toy hauler?
