GMC Sierra 2500 HD Trailer Hitch Buyer’s Guide (Canada)

Shopping a trailer hitch for a GMC Sierra 2500 HD in Canada? Start with the door-sticker tow limit on this heavy-duty pickup, then open the live CURT rear-receiver shelf we stock for listed Sierra 2500 HD years. CURT 13447 is the in-stock Class 3 hitch with a two inch receiver for two thousand twenty through two thousand twenty-six Silverado and Sierra HD on the live card. The hitch card rates about eight thousand pounds gross trailer weight and eight hundred pounds tongue weight, with weight-distribution notes on that same sheet. Door sticker first. Hitch second. Heavier Class 4 and Class 5 cards sit beside it when the sticker and trailer ask for more. Canada orders often ship free on qualifying baskets, so confirm the cart note before you check out.

Parts-counter shortcut. Start with the door sticker, open the live CURT hitch card for your Sierra 2500 HD year and box length, then plan lights and brakes before the first night tow. Broader Canada shopping help lives in our buying guide, how to choose a hitch, what hitch class do I need, and Silverado hitch guide when you are shopping the lighter 1500 badge instead.

The live hitch path for listed Sierra 2500 HD years

CURT 13447 is a Class 3 hitch with a two inch receiver for two thousand twenty through two thousand twenty-six Silverado and Sierra HD on the live card. On the hitch card it rates about eight thousand pounds gross and eight hundred pounds tongue, with weight-distribution notes on the sheet. When you need more hitch capacity on those late-model years, CURT 14005 opens a Class 4 two inch path, and CURT 15010 is the Class 5 option with a two and one half inch receiver rated about twenty thousand pounds gross and two thousand seven hundred pounds tongue on the hitch card.

Mid-cycle two thousand fifteen through two thousand nineteen Sierra 2500 HD trucks often sit on CURT 13178 Class 3 for the six and one half foot box path, with CURT 14009 Class 4 on that same box length and CURT 14010 Class 4 on the eight-foot box sheet. Older two thousand one through two thousand ten years lean on CURT 15302 Class 5 for many six and one half foot box trucks, with CURT 13208 Class 3 and CURT 15312 Class 5 for the eight-foot box path. Cab and chassis HD trucks use different cards such as CURT 15800 or 15400, so do not order a pickup hitch for a cab and chassis frame by guesswork.

We do not invent a Sierra 2500 HD-only wiring harness promise across every listed year here. Many of these trucks already carry a factory seven-way, but still confirm lights and a brake-controller path before the first Canadian night tow. Gooseneck and fifth-wheel gear stays an in-bed conversation on the year landers.

CURT 13447 Class 3

In-stock two inch Class 3 for listed two thousand twenty and newer Silverado and Sierra HD years on the live card. Practical late-model starting point when everyday bumper-pull duty fits the door sticker.

Parts-counter note. Confirm box length and pickup versus cab and chassis before you order. Step to 14005 or 15010 when the trailer and sticker ask for more. Older years lean on 13178 or 15302.
