Pick your Sierra 2500 HD year

Each year page has the hitch, the harness and the ball mount that go together, with the price of each.

Class 3 or Class 5 on a Sierra 2500 HD?

Class 3 is the lighter one, with a 2-inch receiver and 8,000 lb of trailer. It's plenty for a bike rack, a cargo carrier, a utility trailer or a small boat. Class 5 moves you to a 2-1/2 inch receiver and 20,000 lb, which is what you want for a camper, a boat or a loaded equipment trailer. Either way the Sierra 2500 HD's own tow rating in the owner's manual is the ceiling, and the lower number wins.

Ball mountDrop, rise and ball size, sorted in two minutes. Loaded mounts from $41.70 CAD.

Salt-crusted pickup bumper with a receiver cover in winter

Salt and winter careGrease the pin, cap the receiver, rinse in spring. The hitch outlasts the Sierra 2500 HD.

A bike rack needs nothing but the hitch. A trailer needs lights, and CURT 52107 ($130.05 CAD) is the four-flat harness that plugs into the Sierra 2500 HD's factory connector for 2024. No cutting, no scotch-locks. Other years have their own harness; the year page shows the right one.

Then a ball mount sized to the receiver: CURT 45371 ($134.41 CAD) drops straight into a 2-1/2 inch receiver. Pick the drop or rise that keeps the trailer level, and match the ball to the coupler. The ball mount guide covers both in two minutes.

Canadian winters eat hitch hardware. Salt and brine get into the receiver and the trailer plug, so a smear of grease on the pin, a cap on the receiver and a rinse under the bumper in spring keep a CURT hitch looking new for years. The rust and salt care guide has the full routine.

GMC Sierra 2500 HD hitch questions

Which CURT hitch fits my GMC Sierra 2500 HD?

It depends on the year. CURT 15010 is the newest, for 2020 through 2026, and the table above matches every other year to its part. Open your year page and the exact hitch, price and wiring are on it.

Can I put a bike rack on a Sierra 2500 HD with this hitch?

Yes. The 2-1/2 inch receiver takes any 2-1/2 inch rack, and a loaded rack counts against the hitch's tongue weight (2,700 lb on CURT 15010), so a four-bike platform rack with bikes on it is well inside the limit.

Can I install the hitch myself?

Most owners do. CURT rates CURT 15010 a novice install, about 30 minutes with hand tools and a jack. The install video above is the real job, uncut.

How much can a Sierra 2500 HD tow with a CURT hitch?

The hitch is rated from 6,000 lb to 20,000 lb depending on the part, but the Sierra 2500 HD's own tow rating in the owner's manual is the ceiling. The lower of the two numbers is your limit, every time.
