$722.10Your 1999 GMC Sierra 1500 has six CURT hitches to choose from, and the right one comes down to what you're pulling and what you'll hang off the receiver. CURT 14332 is a Class 4 hitch with a 2-inch receiver, rated to 10,000 lb gross trailer weight and 1,000 lb tongue weight, $411.22 CAD. It doesn't fit a Sierra 1500 with a Roll Pan Bumper or Tommy Gate Lift or 10" Drop Bumper. Every one ships free anywhere in Canada.
- CURT 13339 is a Class 3 hitch with a 2-inch receiver, rated to 8,000 lb gross trailer weight and 800 lb tongue weight, $363.86 CAD.
- CURT 13042 is a Class 3 hitch with a 2-inch receiver, rated to 6,000 lb gross trailer weight and 600 lb tongue weight, $479.14 CAD.
- CURT 13322 is a Class 3 hitch with a 2-inch receiver, rated to 6,000 lb gross trailer weight and 600 lb tongue weight, $271.09 CAD.

Trailer lights are a plug-in job on this one. CURT 56000010 is the seven-way RV plug harness for the 1999 GMC Sierra 1500, $402.54 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 1999 GMC Sierra 1500
A bike rack only needs the hitch. A trailer needs all three, and every piece ships free anywhere in Canada.

1999 GMC Sierra 1500 hitch questions
Which trailer hitch fits a 1999 GMC Sierra 1500?
CURT 14332 (Class 4, 2-inch receiver, 10,000 lb), CURT 13339 (Class 3, 2-inch receiver, 8,000 lb), CURT 13042 (Class 3, 2-inch receiver, 6,000 lb), CURT 13322 (Class 3, 2-inch receiver, 6,000 lb), and CURT 13332 (Class 3, 2-inch receiver, 6,000 lb) and more 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 1999 GMC Sierra 1500 tow with this hitch?
The hitch is rated to 10,000 lb gross trailer weight and 1,000 lb tongue weight, or 12,000 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 1999 GMC Sierra 1500?
If a trailer is going on, yes. Brake and turn signals have to work, and CURT 56000010 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 14332 doesn't fit a Sierra 1500 with a Roll Pan Bumper or Tommy Gate Lift or 10" Drop Bumper. The full fit table is on each product page, so check it before you order.
