LETSYEE anti-rattle hitch pin shim kit for 2" receiver — 1/2" pin hole, solid steel yellow-zinc, reduces wobble & noise

LETSYEE Upgrade 22321 is a steel anti-rattle hitch pin shim kit that secures hollow-shank 2" receiver accessories and reduces wobble, vibration, and noise for quieter towing.

This compact kit combines a shim, welded bracket, threaded bolt, and anti-rattle pin to lock a ball mount or hitch-mounted accessory firmly in place. Built from solid steel with a yellow zinc finish, the components resist corrosion while giving a tighter fit between a 2" x 2" receiver and hollow shank accessories with a 1/2" pin hole. The kit is designed for easy installation and comes with a 5-year warranty for added peace of mind.

How does this kit stop hitch noise and movement?

The LETSYEE anti-rattle system prevents play between the accessory shank and receiver tube by filling gaps and clamping parts together. The welded bracket and bolt pull the shank toward the receiver wall while the pin locks the assembly, drastically reducing the surfaces that can vibrate.

• Shim fills the void between shank and receiver to stop lateral movement.
• Welded bracket and bolt pull the shank tight for a rigid fit.
• Anti-rattle pin secures the entire assembly in the 1/2" pin hole.
• Solid-steel construction transfers load, not noise, to the hitch.

Which hitch accessories and receivers are compatible?

This kit is made for hollow-shank accessories that slide into a 2" x 2" receiver tube and use a 1/2" hitch pin hole. It works with many common towing add-ons where shank wobble causes noise or wear.

• Compatible with ball mounts, cargo carriers, bike racks, and hitch trays.
• Fits 2" receivers with 1/2" pin holes (verify hollow shank before ordering).
• Not intended for solid-shank accessories or oversized/undersized receivers.
• Universal use across most light- and medium-duty towing setups.

How simple is installation and what tools are required?

Installation is straightforward: insert the shim into the shank, seat the accessory in the receiver, thread and tighten the bolt through the welded bracket, then install the hitch pin. A basic wrench set is all you need; no welding or fabrication required.

• Slide shim into the hollow shank before inserting accessory into receiver.
• Align welded bracket and thread bolt, then tighten with a wrench.
• Insert the 1/2" hitch pin and secure with clip or lynch pin if provided.
• Check tightness periodically, especially after initial road miles.

What materials and protections keep the kit durable outdoors?

The LETSYEE kit uses heavy-duty steel components with a yellow zinc plating that slows rust and abrasion. The reinforced zinc finish protects threaded surfaces and bearing points against corrosion from rain, road salt, and mud.

• Solid-steel construction for structural strength under load.
• Yellow zinc finish provides corrosion resistance and wear protection.
• Threaded bolt and bracket made to resist loosening under vibration.
• Designed to hold up in routine towing conditions and seasonal weather.

Who is this for: The LETSYEE Upgrade 22321 anti-rattle hitch pin shim kit is aimed at vehicle owners who tow with 2" receivers and hollow-shank accessories and want a quieter, more secure connection. It's ideal for drivers using ball mounts, cargo carriers, bike racks, and similar hitch-mounted gear who prefer an easy-install, corrosion-resistant solution. Verify your receiver size and shank type before purchasing to ensure compatibility.
