$125.78Your 2019 GMC Sierra 1500 has three CURT hitches to choose from, and the right one comes down to what you're pulling and whether your Sierra 1500 came with a factory receiver. CURT 15307 is a Class 5 hitch with a 2-inch receiver, rated to 16,000 lb gross trailer weight and 2,000 lb tongue weight, $540.36 CAD. It's for a Sierra 1500 that came with the factory receiver. Every one ships free anywhere in Canada.
- CURT 14019 is a Class 4 hitch with a 2-inch receiver, rated to 10,000 lb gross trailer weight and 1,000 lb tongue weight, $510.00 CAD. It's for a Sierra 1500 that didn't come with the factory receiver.
- CURT 13393 is a Class 3 hitch with a 2-inch receiver, rated to 6,000 lb gross trailer weight and 600 lb tongue weight, $289.76 CAD. It's for a Sierra 1500 that didn't come with the factory receiver.
There's a front receiver too. CURT 31088 mounts behind the front bumper of the 2019 GMC Sierra 1500, rated to 5,000 lb with 500 lb tongue weight, $317.77 CAD.
Trailer lights are a plug-in job on this one. CURT 56072 is the seven-way RV plug harness for the 2019 GMC Sierra 1500, $113.41 CAD, and it clicks into the factory connector so you're not splicing wires behind the bumper. A second harness fits as well; both are below.
What you need to tow with a 2019 GMC Sierra 1500
A bike rack only needs the hitch. A trailer needs all three, and every piece ships free anywhere in Canada.
- CURT 15307 hitch, $540.36 CAD. The receiver that bolts to the Sierra 1500.
- CURT 56072 wiring harness, $113.41 CAD. Plugs in, no splicing; the trailer lights follow the Sierra 1500's.
- CURT 45836 ball mount, $41.70 CAD. Ball mount with the ball already on it, ready to hook a trailer. Bigger coupler? CURT 45041 carries a 2-5/16-inch ball, $62.42 CAD.

2019 GMC Sierra 1500 hitch questions
Which trailer hitch fits a 2019 GMC Sierra 1500?
CURT 15307 (Class 5, 2-inch receiver, 16,000 lb), CURT 14019 (Class 4, 2-inch receiver, 10,000 lb), and CURT 13393 (Class 3, 2-inch receiver, 6,000 lb) all fit. Pick the class that covers your trailer with room to spare, then check the fit table on the product page for your build.
How much can a 2019 GMC Sierra 1500 tow with this hitch?
The hitch is rated to 16,000 lb gross trailer weight and 2,000 lb tongue weight, or 17,000 lb with a weight-distribution hitch. Your Sierra 1500 has its own tow rating in the owner's manual, and the lower number is your limit. A loaded bike rack counts against tongue weight too.
Do I need a wiring harness for the 2019 GMC Sierra 1500?
If a trailer is going on, yes. Brake and turn signals have to work, and CURT 56072 plugs into the factory connector so the trailer lights follow the Sierra 1500's. Order it with the hitch and it's one install.
Will it fit my Sierra 1500?
Nearly every build, with a few exceptions. CURT 15307 is for a Sierra 1500 that came with the factory receiver. CURT 14019 is for a Sierra 1500 that didn't come with the factory receiver. CURT 13393 is for a Sierra 1500 that didn't come with the factory receiver. The full fit table is on each product page, so check it before you order.
