How to Select a Trailer Hitch
Pick hitch class and receiver size first. Anti-rattle kits and sway bars both need the right tube and accessory match.
Watch on YouTubePeople mix up hitch stabilizers and trailer sway bars all the time. A hitch stabilizer or anti-rattle kit tightens a bike rack, cargo carrier, or empty receiver so the tube stops clanking on Canadian frost heaves. A trailer sway control bar fights side to side trailer motion once you are actually towing. Both can say stabilizer on a box, and both can live in a CURT drawer, but they solve different problems. This page keeps the counter conversation honest.
All four videos are from the official CURT YouTube channel (@curtmfg). Use them for hitch class basics, install habits, wiring, and ball-mount height while you sort rattle from sway.

Watch on YouTubeInstall habits still matter. A loose pin or soft torque job can sound like a rattle problem that is really hardware.
Watch on YouTubeTrailer lights and harness health are part of a tow day even when the complaint started as noise in an empty receiver.
Watch on YouTubeBall mounts and sway-tab mounts belong in the towing conversation. Bike-rack shanks belong in the anti-rattle conversation.
Watch on YouTubeUse this when a bike rack, cargo carrier, or empty receiver clanks, buzzes, or chatters. The kit wedges or tensions the shank inside the tube so metal stops dancing.
Use this when a trailer yaws side to side behind you on the highway. The bar links the trailer A-frame to a sway tab or weight-distribution setup to damp that motion.
An anti-rattle hitch stabilizer is a quieting tool for the receiver tube. Hollow shanks on bike racks and cargo carriers love to knock around inside a one and one quarter inch or two inch opening. On Canadian roads that chatter gets old fast. CURT 22315 is the live kit we stock for one and one quarter inch tubes. CURT 22321 covers two inch tubes. CURT 22323 is the anti-rattle hitch pin and shim path for a two inch receiver with a five eighths inch hole when that card matches your insert.
None of those parts steer a trailer. They do not replace tongue weight, tire pressure, or a proper pin. If the noise is an empty tube with nothing inserted, a cover can help cosmetics and keep grit out, but a cover alone rarely kills a deep clank the way a tension kit does. For the full noise walkthrough, open the hitch rattle noise fix guide.
A trailer sway control bar is a towing part. CURT 17200 is the live sway control kit we stock. It mounts between the trailer A-frame and a sway tab on the ball mount or weight-distribution setup. CURT 17201 is the trailer-mounted sway ball that pairs with that kit when the trailer frame needs the matching attachment. CURT 45820 is a live sway-tab ball mount path when your setup needs the tab built into the mount.
We do not invent legal cutoffs for when a sway bar is required. Manufacturer manuals, trailer shape, tongue weight, and how the combo feels in the first miles all matter. If the complaint is yaw with a trailer on, start with the do I need a sway bar guide and the first-miles checklist. Fix tongue weight and tire pressure before you throw hardware at a packing problem.
