Just hitches that respect the Multipro setup and still handle real towing work. Every one of these picks earns its spot, not guesswork, not hype, just stuff that actually works and keeps your tailgate in one piece.

How to Choose the Best Trailer Hitches for GMC Multipro Tailgate
You’ve got a GMC truck with that Multipro tailgate, which is great until you bolt on the wrong hitch and the tailgate smacks straight into it. That fancy multi-step setup doesn’t forgive bad choices. Not every hitch works with it, no matter what the product listing claims.
Some hitches block the step function. Others stick out just enough to turn a simple tailgate drop into a dent. Replacing a Multipro tailgate is not cheap. This is one of those “slow down and think first” purchases. Measure. Check clearance. Then buy.
Why the Multipro Tailgate Complicates Things
The Multipro tailgate doesn’t just drop down. It folds, swings, splits, and lowers in stages. That inner gate comes down very close to the bumper, closer than most people expect. A standard ball mount that sticks out too far can easily get in the way.
Drop length matters here more than folks realize. Even a small difference in how far the hitch extends can be the difference between clean clearance and metal meeting metal. A hitch that works fine on a regular tailgate can be a problem on a Multipro. Adjustable or easily removable setups tend to work better.
Picking the Right Hitch Class
Most GMC Sierra and Sierra HD owners end up with a Class III or Class IV hitch. Towing a small boat, utility trailer, or light camper? Class III usually covers it. Heavier campers or equipment trailers push you into Class IV territory.
Adjustable drop hitches are popular because they give you flexibility, usually in the 6 to 8 inch range. That helps with trailer leveling and tailgate clearance. Just remember, more moving parts can mean more noise. If you tow often, anti-rattle features are not optional. They save your ears and your patience.
Hitch Styles That Actually Work With the Multipro
Flush-mount and removable ball mounts are your friends here. When you’re not towing, you can pull the ball or fold the hitch out of the way, keeping the tailgate safe and usable.
Brands like B&W, Curt, and Gen-Y make options that sit tighter to the bumper or fold up when not in use. B&W’s fold-away designs are popular for a reason. Curt’s low-profile and dual-ball setups also keep things compact.
Pin Hole Placement and Shank Length
This is where a lot of people mess up. If the pin hole is positioned too close to the end of the shank, the whole hitch sticks out farther than it needs to. That extra inch or two is often exactly where the Multipro tailgate wants to land.
Look for hitches with shorter overall length or adjustable designs that can slide inward enough to clear the inner gate. If your truck has an aftermarket bumper, double-check everything. Factory measurements don’t always apply anymore.
Don’t Ignore Materials and Finish
Not all steel is created equal. Cheap hitches rust fast, especially if you deal with rain, snow, or salted roads. Once rust sets in, removing the hitch becomes a fight, and a stuck hitch means limited tailgate movement and towing headaches.
Powder-coated or zinc-plated finishes hold up better. Some higher-end hitches even use stainless components in key areas. That costs more upfront but saves frustration down the road.
Features That Are Actually Worth the Money
If you tow regularly, things like anti-rattle systems, locking pins, and built-in sway control are worth paying for. Wind, uneven loads, and long highway runs expose every weak point in a cheap setup.
If you swap between different trailers often, dual-ball or tri-ball hitches are a huge time saver. No tools. No swapping parts in the dirt. Just flip and go.
Where Most People Get It Wrong
Most damage happens because people don’t think about the tailgate until after it’s scratched or bent. They buy the cheapest hitch they can find, assume it fits, and only realize the mistake once the gate comes down.
Another common mistake is ignoring the truck’s actual tow rating. A hitch rated for 10,000 pounds doesn’t magically increase what your truck can handle. Always match the hitch rating with your GMC’s factory tow limits.
The Simple Takeaway
If you’re running a GMC with a Multipro tailgate, your hitch needs to do four things: clear the tailgate, sit tight to the bumper, handle your trailer weight, and hold up over time. That’s it.
Focus on clearance, adjustability, rust resistance, and anti-rattle design. Get those right, and you’ll avoid most of the problems people complain about. Do it once, do it right, and your tailgate stays intact.
