CURT Anti-Rattle Hitch Clamp for 2-Inch Receiver — Model 45367, Stainless Steel, Fits Hollow & Solid Shanks

CURT's Anti-Rattle Hitch Clamp (model 45367) is a stainless-steel and aluminum device that clamps over a 2" receiver shank to reduce noise and movement between the hitch and receiver.

When towing, even small amounts of play between the hitch accessory and receiver can cause annoying clanks, vibrations, and premature wear. The CURT anti-rattle clamp is engineered to compress around either hollow or solid 2" shanks and lock them firmly against the receiver tube. It installs with basic hand tools, resists corrosion with a clear zinc finish, and is adjustable so you can dial in a snug fit.

How does this clamp reduce hitch noise and movement?

The clamp squeezes the shank and receiver opening together, removing the small gaps that let the assembly shift under load. Eliminating that tolerance reduces audible rattles and the micro-movement that can create wear.

• Wraps around the shank and receiver tube to close play
• Tightens with two nuts for even clamping pressure
• Compatible with hollow and solid shanks for universal application

Is installation difficult and what tools are required?

Installation is straightforward and designed for DIY use—no specialty tools required. Place the U-bolt over the shank and receiver opening, then thread and tighten the nuts with a standard wrench until the clamp is firmly seated.

• Requires only commonly owned hand tools (wrenches)
• Fast install—typically only a few minutes
• Adjustable nuts let you fine-tune the fit without disassembly

Will this fit my trailer accessory or bike rack?

This clamp is made to work with any standard 2" receiver and fits both hollow and solid shank accessories. It does not replace a hitch pin; it works alongside a properly secured pin to keep the connection tight.

• Designed for 2" receiver tubes (standard class III/IV style)
• Compatible with ball mounts, cargo carriers, bike racks, and more
• Must be used with a correctly installed hitch pin for safety

What materials and finish protect it from the elements?

CURT combined stainless steel and aluminum components to balance strength with corrosion resistance. A clear zinc coating adds another barrier against rust, extending service life in wet or salty conditions.

• Stainless-steel hardware where strength is required
• Lightweight aluminum parts to limit added weight
• Clear zinc finish for additional corrosion protection

Who is this for: The CURT Anti-Rattle Hitch Clamp 45367 is ideal for drivers who tow frequently and want a quieter, tighter connection—owners of trucks, SUVs, or vans who use ball mounts, cargo carriers, bike racks, or other 2" receiver accessories. It's particularly useful for people who prefer a simple, tool-only installation and want a durable clamp that resists corrosion while improving towing comfort and reducing wear.
