The Curt A20 5th Wheel Trailer Hitch with S20 Slider is built from sturdy steel and rated for 20,000 lbs gross towing weight and 5,000 lbs vertical load limit. The heavy-duty construction and carbide powder coat finish give it the backbone to handle long hauls with demanding 5th-wheel trailers. It mounts securely in your truck bed using the included base rails and installation kit, providing a strong foundation for stable towing mile after mile.
This hitch takes the stress out of the ride with its interlocking 2-jaw system that wraps completely around the king pin for 360-degree contact. That tight connection cuts down on rattle and movement compared to slide-bar models, giving you a quieter, more secure feel. The fully articulating torsion head helps suppress road shock and smooths out bumps so you can tow with greater control and comfort.
Short-bed truck owners will appreciate the S20 slider’s 12" of fore/aft travel that helps prevent contact between the cab and trailer during slow-speed turns. The non-binding design automatically latches in both directions, so you only need to exit the truck once when adjusting. It’s designed for use on beds shorter than 8' (not recommended for those under 6'), giving you the space you need to back up and park without worry.
The 3-point indicator system shows red when uncoupled, yellow when ready to couple, and green when locked for towing—so you can confirm your connection at a glance. The handle locks to secure the trailer with a padlock (sold separately) and resets automatically after uncoupling. With its self-aligning head and included lube plate for smooth engagement, hitching up becomes a quick, straightforward process every time.
When it’s time to use your truck bed for something else, removal is straightforward thanks to the fast 1-pin head removal design. One person can lift off the head without extra tools or heavy lifting equipment. Grease fittings built into the base make upkeep simple too—just add lubrication through the two zerk fittings to keep everything running smoothly between trips.

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..

This was very difficult to install. I feel like it could have easily been designed for an easier install. All the threads were poor, and they all had to be chased with a tap & die. After getting it installed I ended up buying a 5th wheel with a gooseneck hitch - so I replaced it with a ball hitch.

1 Year later, the brackets and rails still look new. the paint hasnt chipped or faded. I interchange a 5th wheel saddle and gooseneck ball plate often and even the paint near the mounting points still looks good.
