Frequently Asked Questions

Do you need a hitch lock to prevent trailer theft?

A hitch lock is one of the most effective deterrents against trailer theft. Receiver hitch locks prevent someone from removing the pin and disconnecting your trailer, while coupler locks block the coupler from being placed on another hitch ball. For parked trailers, pairing a coupler lock with a trailer wheel lock provides two layers of theft prevention — especially important for trailers left at job sites, campgrounds, or driveways overnight.

What is the difference between a hitch pin and a hitch lock?

A standard hitch pin holds the ball mount in the receiver but has no locking mechanism — anyone can pull the pin and remove the ball mount. A hitch lock replaces the pin with a keyed or combination-locking device that prevents unauthorized removal. For any truck that tows regularly, upgrading from a basic pin to a CURT or Master Lock hitch lock adds security for minimal cost.

How do I know what size receiver adapter I need for my hitch?

Receiver adapters are sized by the shank dimensions of your ball mount and the receiver tube opening on your truck. The most common conversion is a 2-inch to 1.25-inch adapter, which allows a smaller ball mount to fit in a larger Class III or IV receiver. Measure your receiver tube opening and the shank of your ball mount — then select an adapter sleeve that matches both dimensions. Always check the weight rating of the adapter against your towing load.

What is an anti-rattle device and does it stop hitch noise while towing?

An anti-rattle device eliminates the gap between your ball mount shank and the receiver tube, which causes the metal-on-metal clunking and rattling noise during braking, acceleration, and bumps. Most anti-rattle devices are either a wedge-style insert or a locking pin with a tightening mechanism. They significantly reduce or eliminate hitch noise and also prevent ball mount wobble, giving a tighter and more controlled towing feel.

Are hitch covers universal or do they come in different receiver sizes?

Hitch covers come in two standard receiver sizes — 1.25-inch for Class I and II receivers, and 2-inch for Class III, IV, and V receivers. Within those two sizes, hitch covers are universal and fit any brand or model of truck with that receiver opening. Branded covers for Ford, Ram, Chevy, GMC, and Jeep are cosmetic and plug directly into the receiver tube to keep out dirt, debris, and moisture when not towing.

What is the difference between a 5th wheel lock and a coupler lock?

A 5th wheel lock secures the king pin of a 5th wheel trailer into the hitch jaw, preventing the trailer from being uncoupled and stolen. A coupler lock blocks the coupler mechanism on a bumper-pull trailer so it cannot be placed on a hitch ball. Both are designed for parked trailer security, but they fit completely different towing setups — 5th wheel locks for 5th wheel and gooseneck trailers, coupler locks for standard bumper-pull trailers with A-frame or channel-mount couplers.
