How to Select a Trailer Hitch
Hitch class explains the receiver you are buying. It does not rewrite the tow rating printed for your vehicle.
Watch on YouTube →Hitch versus Vehicle Tow Rating (Canada)
Bought a Class 3 hitch and figured the truck or SUV can now pull whatever that hitch stamp says? Pause. The hitch rating is not automatically your vehicle tow rating. In Canada we tell shoppers to treat the door sticker and the owner manual as the vehicle side of the story, then compare that to the hitch card, the ball mount, the trailer coupler, and the tires. The lowest honest number in that chain is the one that wins. This page is a practical myth-buster, not a legal checklist, and we do not invent provincial cutoffs or ticket thresholds.

Trailer Hitch Installation Techniques
CURT · Install habits
A clean install still has to respect the vehicle rating on the door sticker and in the owner manual.

Lights and harnesses keep you legal and visible. They do not raise how much the vehicle is allowed to tow.

CURT · Ball-mount height
Ball-mount height keeps the trailer level. Tongue weight still has to fit both the hitch and the vehicle limits.
Watch on YouTube →The myth in one sentence
A hitch rating is the capacity of that hitch assembly when it is installed as directed. Your vehicle tow rating is whatever the manufacturer published for that exact truck, SUV, or car, usually on the door jamb sticker and in the owner manual. Those are two different documents. Buying a stronger hitch does not mint a stronger vehicle.
Weakest link mindset
Parts-counter talk is simple. Line up the numbers you can actually verify, then tow to the lowest honest one.
Vehicle
Door sticker and manual
Find the manufacturer tow rating and any tongue-weight notes for your exact year, engine, and package.
Hitch
Live hitch card
Read the gross trailer weight and tongue weight on the CURT card that lists your vehicle. Confirm year fitment there.
Hardware
Ball mount and ball
The mount and trailer ball have their own stamps. A Class 3 hitch cannot rescue an undersized ball.
Trailer
Coupler, tires, load
Trailer GVWR, tire load ratings, and how you packed the box all matter. The chain is only as strong as the softest link.
Where shoppers get confused
| Situation | What we tell shoppers |
|---|---|
| Hitch stamp looks bigger | Great for the hitch. Still read the door sticker. If the vehicle rates lower, tow to the vehicle number. |
| Door sticker looks bigger | You still need a hitch, mount, and ball that meet or beat the load you actually pull. Do not assume the factory bumper loops are enough. |
| Factory hitch already there | Open factory hitch keep or replace. Keeping a sound factory receiver can be the right call. Replacing it is a different shopping trip. |
| Class shopping | Use what hitch class do I need to match receiver size and typical jobs, then still check the vehicle rating. |
| Tongue weight | Tongue weight is often the number people skip. Read tongue weight explained before you load the front of the trailer light. |
| Weight distribution | WD can help a setup that is already inside ratings. It is not a free upgrade past the door sticker. See when do I need weight distribution. |
