How to Select a Trailer Hitch
Match hitch class to the door sticker and the live card before you shop a heavier trailer than the vehicle can honestly tow.
Watch on YouTubeAdjustable Ball Mount Tips (Canada)
Looking for practical adjustable ball mount tips in Canada? Start by matching shank size to the receiver tube, then open CURT 45900 for the two inch adjustable channel mount, CURT 45902 for the two and one half inch adjustable channel mount, or CURT 45810 when you need a multi-use mount that keeps an accessory tube open while a trailer ball is fitted. Adjustable channel mounts help you dial rise versus drop so the trailer rides level. Multi-use mounts are a different job: they add a second tube for a rack or cargo piece while you still tow. This page is about those adjustable and multi-use habits, not a redo of breakaway kit or charger essays, bike tray tips, round-bar weight distribution, gooseneck chain, pintle, dual-receiver, or cargo net pages. Confirm ratings on the live product cards. Canada orders often ship free on qualifying baskets, so confirm the cart note before you check out.

Watch these CURT videos first
All four videos are from the official CURT YouTube channel (@curtmfg). Use them for class selection, install habits, wiring basics, and ball-mount height before you dig into the product cards below.
If an embed does not load, use the YouTube link under the card. Adjustable ball mount shoppers still need an honest tube size, a level trailer height, and the lowest rating in the hitch stack before they treat a channel mount as a fix for every towing question.
Trailer Hitch Installation Techniques
Confirm the live card still lists your year and configuration. Shared sheets are easy to mix up when sibling badges sit nearby.

Watch on YouTubeWhat these live CURT mounts actually do
CURT 45900 is the two inch adjustable channel-style ball mount on the live card. It mounts in a two inch by two inch receiver tube, flips for about five and one quarter inches of max rise or six inches of max drop, and lists two hitch pin holes for about eleven inch or twelve inch shank length. The live notes list a two inch ball rating around ten thousand pounds and a two and five sixteenths inch ball rating around fourteen thousand pounds. Built-in anti-rattle language on the card is a comfort note, not a free pass to ignore pin and clip habits.
CURT 45902 is the two and one half inch adjustable channel-style ball mount on the live card. Same rise and drop story, same pin-hole shank lengths, but it mounts in a two and one half inch receiver tube. The live notes list a two inch ball rating around ten thousand pounds and a two and five sixteenths inch ball rating around twenty thousand pounds. Use 45902 only when the hitch tube is honestly two and one half inch. Forcing a two inch shank into a larger tube without the right bushing path is how noisy tows start.
CURT 45810 is the multi-use ball mount on the live card. It fits a two inch receiver tube, accepts a one inch ball shank hole, and adds an extra receiver tube so an accessory can stay mounted while you tow. That is a different job from the adjustable channel mounts above. Capacity honesty means the lowest rating among the hitch, ball, mount, and trailer still wins. Do not invent a legal cutoff on this page, and do not invent a gross rating the live 45810 card does not print.

How to choose without guessing
Step 1Match the tube
Two inch shanks stay on two inch tubes. Two and one half inch shanks stay on two and one half inch tubes. Guessing from a photo is how mounts get returned.
Step 2Level the trailer
Use rise versus drop on the adjustable channel to get the trailer frame level. Open the rise tips page for the deeper habit notes.
Step 3Read the lowest rating
Take the lowest honest rating among the hitch, ball, mount, and trailer. Do not invent a legal cutoff from a parts essay.
Step 4Use sibling tips when needed
Weight-distribution setup, sway-tab habits, and measuring drop stay on those existing tips pages instead of being reinvented here.
