How to Select a Trailer Hitch
Why a compact luxury crossover like the Envision often lands on a Class 3 two-inch receiver, then still respects the door-sticker tow limit even when the hitch class looks truck-adjacent.

Shopping a trailer hitch for a Buick Envision in Canada? Start with the year on the door sticker before you open a CURT Class 3 card, because the two live hitch SKUs do not share the same tongue rating story. We stock CURT 13405 for listed 2019 through 2020 Envision years and CURT 13479 for listed 2021 through 2022 Envision years. Dedicated wiring CURT 56364 covers listed 2017 through 2020 Envision years, and CURT 56325 covers listed 2021 through 2025 Envision years on a shared multi-vehicle harness card. Early 2016 through 2018 hitch coverage is an honest gap on this shelf.
Built for Canadian Buick Envision owners and shops. Free shipping on CURT towing gear from Lots of Parts when the SKU is live on this store.

Read the year first. Listed 2019 through 2020 Envision years open CURT 13405, a Class 3 hitch with a two-inch receiver rated to three thousand five hundred pounds gross trailer weight and five hundred twenty-five pounds tongue weight on the card. Listed 2021 through 2022 Envision years open CURT 13479, also a Class 3 two-inch hitch, but the live card rates it to two thousand pounds gross trailer weight and two hundred pounds tongue weight. That rating drop is real. Match the year, then read the door sticker before you plan a load. We do not invent an early 2016 through 2018 hitch SKU on this shelf.

Wiring that actually lists the Envision
CURT 56364 covers listed 2017 through 2020 Envision years. CURT 56325 covers listed 2021 through 2025 Envision years and also lists XT5, XT6, Blazer, and Acadia years on the same harness card. Confirm Envision is listed before you buy, and do not stretch XT5 exclusions onto an Envision without reading the live notes.

Parts-counter notes before you click buy
| Topic | What we tell shoppers |
|---|---|
| Class 3 with a caveat | Both hitch cards are Class 3 with a two-inch tube, but 13479 carries a lower card rating than 13405. Read both the hitch card and the door sticker. |
| Early hitch gap | We do not invent an in-stock Envision hitch for 2016 through 2018 on this shelf, even when early wiring 56364 starts in 2017. |
| 2022 year lander | 13479 lists 2022, but we only publish Envision year landers through 2021 today. Confirm the product card if your door sticker says 2022. |
| Shared 56325 harness | 56325 also lists XT5, XT6, Blazer, and Acadia. Confirm Envision and any trim exclusions on the live card. |
| Receiver size | Two-inch tube. Match pins, locks, covers, and rack shanks to that size, or use a listed reducer only when the accessory card allows it. |
| Encore kept separate | Encore and Encore GX have their own guides and Class 1 stories. Do not stretch Envision Class 3 cards onto an Encore. |
| Enclave kept separate | Enclave is a different Buick SUV path. Keep Envision shopping on these cards. |
