This hitch is made for serious towing with its 20,000-lb gross towing weight and 5,000-lb vertical load limit. The sturdy steel construction and carbide powder coat finish give it the strength and durability needed for long hauls. It’s a solid base for towing heavy campers or haulers with confidence every time you hook up.
The rounded two-piece, interlocking jaw design wraps completely around the king pin for secure 360-degree contact. That tight fit cuts down on rattling and movement compared to slide-bar hitches, giving you a quieter, more stable ride. The fully articulating torsion head also helps absorb road shock and makes coupling feel smooth and controlled.
Keeping track of your hitch position is simple thanks to Curt’s color-coded lock indicator. A quick look shows you if the hitch is ready to uncouple (red), couple (yellow), or tow (green). The indicator can be seen from the cab or at the hitch itself, so you always know the jaws are set right before pulling out.
The integrated S20 slider gives you 12" of front-to-back travel to create extra clearance when making slow, tight turns. It automatically latches in both directions and moves easily without binding, helping prevent contact between truck and trailer at sharp angles. Built-in zerk fittings make it easy to keep lubricated for consistent performance.
When it’s time to clear the bed, the A20’s head lifts off with a single pin—simple enough for one person to handle. The included adapter rails drop right into the factory puck receivers for quick pin-in setup. It’s a straightforward design that makes switching between towing duty and bed space fast and hassle-free.

Glad you like it, Richard! These are definitely a nicer option than having to buy a whole new hitch! And what did you need to use the hammer for? I'm usually a fan of any percussive maintenance and am definitely curious here.

While I used this with the PullRite hitch it worked very well. I have since sold the hitch as the adaptor to buy a a different hitch no longer needing this adaptor. Worked great.

Hey Paul. I'm glad that Jacob got you all hitched up. What kind of 5th wheel are you towing?

Wow, I don't think I have ever seen a 23 year old hitch, before! That's awesome the rails worked for you. I'm impressed! You really had no issue and didn't have to finagle it at all?

After a year of use, I have no complaints. It does its job just fine. I will also add for others in the market, my father and law has a 2025 Sierra 3500 that he upgraded to, and upgraded his standard 5th wheel hitch to a Andersen Ultimate for the factory puck system. I was able to compare side by side the puck style Andersen to the rail Andersenadapter I have. The height of the hitches are the exact same.

Still satisfied, still recommend. Easy to move hitch in truck as one unit when I need more of the bed available, no further adjustments needed.
