How to Select a Trailer Hitch
Why a Class 1 or Class 3 receiver choice still matters when the only cargo is bikes — tube size and tongue rating set the rack options.

Trying to open a hatch or liftgate with a hitch bike rack still on the receiver? Start with how far the rack sits behind the bumper, whether the rack tilts or folds for rear access, and whether the pin or lock leaves you room to tip the rack without scraping paint. This page is practical Canada clearance help — not a brochure — and it links our hitch-for-bike-rack-only guide, bike-rack cargo guide, and cover-versus-lock page when you need the next step.

Watch these CURT videos first
All four videos are from the official CURT YouTube channel (@curtmfg). Use them for hitch class basics, install habits, wiring context when you also tow, and ball-mount height when a trailer shares the same receiver.

Trailer Hitch Installation Techniques
Install habits that keep the hitch solid before you hang a tilting rack that will move every time you open the hatch.

Wiring is optional for a bike-only setup. Watch this when the same hitch will also pull a small trailer later.
Watch on YouTube →How to Choose a Ball Mount and Trailer Ball
Ball-mount height matters for trailers, not empty bike racks — still useful when the receiver does double duty.
Watch on YouTube →What usually blocks the hatch
Most clearance complaints are simple geometry. A fixed rack sits in the hatch swing path. A tall tire or long downtube hits the glass before the gate opens fully. A pin or lock that is hard to remove keeps you from tilting the rack when you need the trunk for groceries.
Measure once with the rack empty and once with bikes loaded. Loaded bikes move the mass farther back and can change how far you must tip the rack. If the hatch glass kisses a tire at half-open, you need tilt, a longer shank story, or a different rack style — not a tighter wish.
Tilting racks we stock for rear access
These live CURT racks list a tilt-away feature for rear vehicle access. Confirm receiver tube size on each card. Class 1 hitches often use a one and one quarter inch tube. Many tray racks want a two inch tube unless the card lists an adapter sleeve.
Tray rack · two bikes
CURT 18085
Tray-style two-bike rack. Fits one and one quarter inch and two inch receivers with the adapter sleeve on the card. Tilts away for rear access. Sides fold up when empty.
Tray rack · four bikes
CURT 18087
Tray-style four-bike rack for two inch receivers. Tilts away for rear access. Strongest in-stock four-bike tray rack on this page. Confirm tongue rating against your hitch class.
Extendable arms · tilt
CURT 18030
Extendable hitch-mounted bike rack for two or four bikes with the bolt-on arms. Adapter sleeve for one and one quarter inch or two inch tubes. Tilts away and folds for storage.
Support strap
CURT 18050
Sixty-one inch hitch bike rack support strap. Adds stability on longer or heavier rack setups. Does not replace a proper pin or tilt habit.
Pin and lock habits that keep tilt usable
A tilting rack only helps if you can free the tilt mechanism or pull the rack without fighting a seized pin. Match pin diameter to the receiver: one-half inch pins for many Class 1 tubes, five-eighths for common two inch Class 3 tubes. Read the rack and hitch cards before you mix sizes.
Class 1 and 2 pin
CURT 21400
One-half inch hitch pin with clip for one and one quarter inch receivers. Everyday non-locking pin when you want fast rack changes.
Class 3 and 4 pin
CURT 21500
Five-eighths hitch pin with clip for two inch receivers. Simple retention when a lock is not required every day.
Locking pin · smaller tube
CURT 23501
Locking hitch pin for one and one quarter inch receivers. Theft tool first — still leave yourself a clean path to tilt or remove the rack.
Locking pin · larger tube
CURT 23504
Right-angle hitch lock for two inch and larger receivers listed on the card. Useful when the rack stays on overnight.
Anti-rattle clamp
CURT 22320
Anti-rattle hitch clamp for the shank size on the card. Quiets chatter on the road. Confirm it still allows the tilt motion your rack needs.
Parts-counter clearance checklist
| Topic | What we tell shoppers |
|---|---|
| Tilt first | If you open the hatch weekly with bikes aboard, prefer a rack that tilts away. 18085, 18087, and 18030 all list tilt-away rear access. |
| Tube size match | One and one quarter inch Class 1 hitches need racks and pins that list that size. Two inch tray racks such as 18087 need a two inch receiver unless an adapter is on the card. |
| Empty versus loaded | Test tilt with bikes on. Empty racks clear hatches that loaded tires will not. |
| Pin versus lock | Locks deter theft. They are not clearance tools. Keep a workable pin or lock you can operate at the bumper without scraping paint. |
| Cover when empty | When the rack is off, a receiver cover keeps grit out. Covers do not help hatch clearance while the rack is installed. |
| Cargo carriers | Basket carriers change the swing path too. See the bike-rack cargo guide before you mix a carrier and a bike rack on one trip. |
Hatch reality
Geometry first
Measure the hatch arc against the tallest bike on the rack before you blame the hitch.
Tilt habit
Use the feature
A tilting rack only helps when the pin, lock, and anti-rattle hardware still let it move.
Receiver idle
Cover when empty
Shop CURT 22271 for one and one quarter inch tubes or CURT 22272 for two inch tubes.
