2004 GMC Sierra 1500 HD hitch questions
Which trailer hitch fits a 2004 GMC Sierra 1500 HD?
CURT 13322 (Class 3, 2-inch receiver, 6,000 lb) and CURT 13332 (Class 3, 2-inch receiver, 6,000 lb) both 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 2004 GMC Sierra 1500 HD tow with this hitch?
The hitch is rated to 6,000 lb gross trailer weight and 600 lb tongue weight, or 10,000 lb with a weight-distribution hitch. Your Sierra 1500 HD 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.
Does the hitch come with trailer wiring?
No. The hitch is the receiver and hardware. For a bike rack you don't need wiring at all; for a trailer you need a harness, and the wiring guide covers four-flat and seven-way.
