How to Select a Trailer Hitch
Receiver size still matters before you quiet the tube. A one and one quarter inch Class 1 or Class 2 opening needs different pins and kits than a two inch Class 3 tube.
Watch on YouTubeSilent Hitch Pin versus Anti-Rattle (Canada)
A bike rack that clunks in the receiver is usually a loose shank, not a broken hitch. Silent hitch pins and anti-rattle devices cut that receiver chatter for racks and cargo carriers, while a stabilizer clamp helps more when the shank still walks in a larger tube. This Canada tips page walks the practical parts-counter choice between a tightening pin, an anti-rattle kit, and a clamp, then links the deeper rattle, stabilizer versus sway-bar, and bike-rack-only pages already on this store. No invented legal cutoffs.

Trailer Hitch Installation Techniques
Install habits matter for anti-rattle kits. Threaded pins and shims need clean holes and honest clip engagement so the bracket can tighten without chewing the shank.
Watch on YouTubeHow to Connect a Trailer Wiring Harness
Wiring is a separate job. A quiet pin will not fix dark trailer lights, so keep the harness path on its own checklist.
Watch on YouTubeHow to Choose a Ball Mount and Trailer Ball
Ball-mount height is also separate. Level the trailer after the hitch is quiet, not before you chase clunk in an empty rack shank.
Watch on YouTubeWhat that clunk usually is
Most receiver noise is the accessory shank bouncing inside the hitch tube. Bike racks and cargo carriers make it obvious because the mass sits behind the bumper and amplifies every bump. A plain hitch pin holds the shank in place. It does not always take up the clearance between the shank and the tube wall. That leftover gap is the clunk you hear on Canadian washboard pavement.
Silent-style pins and anti-rattle kits attack that gap. Some use a threaded pin and a shim bracket so you can draw the hollow shank tight. Others use a clamp that squeezes the tube and shank together. A sway bar is a different tool for trailer sway on the highway, not for rack chatter in the receiver. Keep those jobs separate.
Silent pin versus anti-rattle kit versus clamp
Tightening pin
Anti-rattle hitch pin and shim
CURT 22323 is the live anti-rattle hitch pin and shim we stock for a two inch receiver with a five-eighths hole. The threaded pin lets you draw a hollow shank tight, which is the common bike-rack and cargo-carrier case.
- Best first step when a hollow two inch shank clunks
- Still uses a clip on the grooved pin
- Not a trailer sway bar
Sized kits
Match the tube
CURT 22321 is the live two inch anti-rattle kit. CURT 22315 is the live one and one quarter inch anti-rattle kit. Buy the kit that matches the receiver you already have, not the rack brand alone.
- Two inch Class 3 tubes use 22321
- One and one quarter inch Class 1 or Class 2 tubes use 22315
- Confirm the live card before you order
Clamp path
When a stabilizer clamp helps more
CURT 22320 is the live anti-rattle hitch clamp we stock for two and one half inch receivers. It squeezes shank movement when a pin kit is not the right size for that larger tube. If your hitch is a common two inch or one and one quarter inch opening, start with the matching pin kit instead.
- Clamp is for two and one half inch tubes on this live card
- Do not force a clamp meant for a larger tube onto a smaller hitch
- See stabilizer versus sway-bar notes before you mix trailer tools
How to choose without overbuying
Step 1Measure the receiver
Confirm one and one quarter inch, two inch, or two and one half inch before you shop a quiet kit.
Step 2Look at the shank
Hollow bike-rack and carrier shanks usually respond to a tightening pin or sized anti-rattle kit.
Step 3Use the right tool for sway
Receiver clunk is not trailer sway. A sway bar belongs on a trailer conversation, not on a bike-rack clunk.
Step 4Still pin and clip
Even a quiet kit needs honest pin and clip engagement. A lock is optional security, not a substitute for retention.

Open live 22323 product →Parts-counter note. Match tube size first. Then decide between a tightening pin, a sized anti-rattle kit, or a larger-tube clamp. Keep trailer sway on a separate page.

| Topic | What we tell shoppers |
|---|---|
| Clunk source | Usually shank clearance in the receiver tube, especially with bike racks and cargo carriers. |
| First quiet step | Match tube size, then try a tightening pin or sized anti-rattle kit for hollow shanks. |
| Clamp path | 22320 is for two and one half inch receivers on the live card. Do not force it onto a smaller tube. |
| Not a sway bar | Receiver quiet kits are not trailer sway control. Open stabilizer versus sway bar for that split. |
| Bike-rack honesty | If the hitch exists mainly for bikes, also read hitch for bike rack only. |
