$38.43Your 1999 GMC K3500 has four 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 15325 is a Class 5 hitch with a 2-inch receiver, rated to 16,000 lb gross trailer weight and 2,400 lb tongue weight, $691.70 CAD. It doesn't fit a K3500 with a Dual Exhaust Or 10" Step Bumper. Every one ships free anywhere in Canada.
- CURT 14081 is a Class 3 hitch with a 2-inch receiver, rated to 10,000 lb gross trailer weight and 1,000 lb tongue weight, $540.77 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 13082 is a Class 3 hitch with a 2-inch receiver, rated to 6,000 lb gross trailer weight and 600 lb tongue weight, $512.48 CAD.
There's a front receiver too. CURT 31042 mounts behind the front bumper of the 1999 GMC K3500, rated to 5,000 lb with 500 lb tongue weight, $305.71 CAD.
Trailer lights are a plug-in job on this one. CURT 55315 is the four-flat plug harness for the 1999 GMC K3500, $38.43 CAD, and it clicks into the factory connector so you're not splicing wires behind the bumper.
What you need to tow with a 1999 GMC K3500

1999 GMC K3500 hitch questions
Which trailer hitch fits a 1999 GMC K3500?
CURT 15325 (Class 5, 2-inch receiver, 16,000 lb), CURT 14081 (Class 3, 2-inch receiver, 10,000 lb), CURT 13042 (Class 3, 2-inch receiver, 6,000 lb), and CURT 13082 (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 1999 GMC K3500 tow with this hitch?
The hitch is rated to 16,000 lb gross trailer weight and 2,400 lb tongue weight, or 17,000 lb with a weight-distribution hitch. Your K3500 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 K3500?
If a trailer is going on, yes. Brake and turn signals have to work, and CURT 55315 plugs into the factory connector so the trailer lights follow the K3500's. Order it with the hitch and it's one install.
Will it fit my K3500?
Nearly every build, with a few exceptions. CURT 15325 doesn't fit a K3500 with a Dual Exhaust Or 10" Step Bumper. The full fit table is on each product page, so check it before you order.
