LETSYEE Anti-Rattle Hitch Pin Shim Kit for 2-inch Receiver — 1/2-inch Pin, Steel Clamp

LETSYEE's Upgrade 22321 Anti-Rattle Hitch Pin Shim Kit is a steel, zinc-plated shim-and-bracket system that eliminates most receiver-to-shank movement for quieter, firmer towing.

If your trailer accessories chatter, clank or shake on the road, this kit is designed to lock a hollow-shank accessory into a 2" x 2" receiver with a 1/2" pin hole. The package combines a wedge-style shim, a welded metal bracket and a threaded bolt-plus-pin to clamp the accessory shank in place, reducing vibration, noise and lateral play. Built from solid steel with a yellow zinc finish, the kit is corrosion-resistant and backed by a 5-year warranty.

How does this kit reduce hitch noise and wobble?

The system works by filling the gap between the hollow shank and the receiver tube and then clamping it tight with a bracket and bolt. That mechanical preload prevents the accessory from shifting under load, which is the main cause of rattling and vibration. It doesn’t rely on rubber or friction alone, so it stays effective under heavy towing conditions.

• Shim fills the internal clearance in hollow shanks to stop side-to-side movement.
• Welded bracket and threaded bolt clamp the shank to the receiver securely.
• Solid steel construction maintains preload even under vibration and weight.

Will it fit my trailer hitch, and what should I measure first?

This kit is made for standard 2" x 2" receivers using accessories with hollow shanks and a 1/2" pin hole. Before buying, confirm your receiver is 2 inches square and your accessory shank is hollow (not a solid bar) with a 1/2" pinhole. If those dimensions match, the kit installs universally across ball mounts, cargo carriers, bike racks and similar accessories.

• Receiver size: 2" x 2" (measure outside-to-outside or check vehicle specs).
• Shank type: hollow shank required (not compatible with some solid shanks).
• Pin hole diameter: 1/2"—verify with caliper or ruler.

How simple is installation and what tools do I need?

Installation is straightforward and typically takes a few minutes with basic hand tools. Slide the shim into the hollow shank, insert the accessory in the receiver, line up the bracket and thread the bolt; tighten with a wrench to set the clamp. No drilling or welding is required for normal use.

• Tools: common wrench or socket set to tighten the bolt and pin.
• Steps: insert shim, install accessory, align bracket, tighten bolt, secure pin.
• Maintenance: inspect and retorque periodically, especially after heavy towing.

What materials and durability features should I expect?

The kit is composed of solid steel components finished with a yellow zinc plating to resist rust and outdoor exposure. That finish helps the hardware hold up against rain, road grime and seasonal corrosion. LETSYEE supports the product with a 5-year warranty and offers replacement support if issues arise.

• Construction: heavy-gauge steel for sustained clamping force.
• Finish: reinforced yellow zinc plating for enhanced corrosion resistance.
• Support: 5-year warranty and seller assistance for replacements or questions.

Who is this for? The LETSYEE Upgrade 22321 Anti-Rattle Hitch Pin Shim Kit is aimed at vehicle owners who tow regularly and want a quieter, more secure connection between their receiver and hollow-shank accessories. It’s ideal for owners of bike racks, cargo carriers, hitch-mounted trays and ball mounts who want to remove play and vibration without expensive aftermarket receivers. Choose this kit if you need a durable, easy-to-install solution that fits standard 2" receivers with a 1/2" pin hole and prefer a steel clamp design backed by a multi-year warranty.
