TOPTOW Trailer Hitch Adapter 2-1/2" to 2" Reducer Sleeve - Carbon Steel, Includes 5/8" Pin

TOPTOW 64028HP is a carbon-steel hitch reducer sleeve that converts a 2-1/2" receiver into a 2" receiver and includes a 5/8" pin and clip for immediate use.

When your truck or trailer has a 2-1/2" Class V receiver but you need to use a 2" ball mount, bike rack, or cargo carrier, this adapter sleeve makes the fit simple and secure. Built from heavy-duty carbon steel with a black powder-coat finish, the TOPTOW 64028HP reduces the receiver size while resisting rust and wear. The sleeve’s engineered lip locates the adapter reliably inside the 2.5" tube so it won’t slide too far into the receiver, and the included 5/8" pin and clip provide a ready-to-install fastening solution.

How does the sleeve ensure a secure fit in a 2-1/2" receiver?

The sleeve features a pronounced locating lip that rests against the inside of the 2.5" tube so the adapter seats consistently and doesn’t slip inward. The universal 5/8" pin hole lines up with standard hitch pins or locks for straightforward retention. That combination minimizes wobble and provides predictable alignment for the inserted 2" shank.

• Raised locating lip prevents the sleeve from sliding into the receiver.
• Standard 5/8" pin hole for compatibility with common hitch pins and locks.
• Approximately 3" clearance from pin-hole center to sleeve flange end for fit checks.

What materials and finish protect it from the elements?

This adapter is made of heavy-duty carbon steel for structural strength under towing loads limited by your hitch and vehicle. A black powder-coat overlay provides a tougher, longer-lasting finish than plain paint, helping resist chipping and corrosion. Regular inspection and proper maintenance will maximize life in wet or salted-road conditions.

• Carbon-steel construction for rugged durability.
• Black powder-coat finish for corrosion and abrasion resistance.
• Welded and machined features designed for towing service environments.

Which towing accessories will this adapter accept and what limitations apply?

The reducer sleeve allows any standard 2" shank accessory—ball mounts, bike racks, cargo carriers, and 2" pintle mount assemblies—to be used in a 2-1/2" receiver. Capacity is governed by the vehicle’s hitch rating and the attached accessory, so always confirm the weakest-rated component to determine safe towing limits. Avoid exceeding trailer weight or tongue weight specified by your hitch or vehicle manufacturer.

• Accepts standard 2" shank accessories: ball mounts, racks, carriers.
• Towing capacity limited by the vehicle hitch, not the sleeve itself.
• Included 5/8" pin and clip secure the adapter for immediate installation.

How easy is it to install and what should you check before buying?

Installation is straightforward: slide the sleeve into the 2-1/2" receiver until the locating lip seats, insert the 5/8" pin through aligned holes, and secure with the clip. Before purchasing, measure your receiver opening and confirm it is the 2-1/2" size and check the pin-hole spacing on your accessory for compatibility. Also verify your hitch class and load ratings to ensure safe use with the adapter.

• Simple slide-in installation with included 5/8" pin and clip.
• Confirm receiver is 2-1/2" and accessory shank is 2" before ordering.
• Verify hitch and vehicle load ratings to determine allowable towing limits.

Who is this for? The TOPTOW 64028HP reducer sleeve is ideal for drivers who own vehicles with Class V (2-1/2") receivers but need to use standard 2" accessories without replacing the entire hitch. It suits truck owners who rotate between heavy-duty towing setups and commonly available Class III/IV ball mounts, as well as cyclists or campers who want to fit bike racks or cargo carriers designed for 2" receivers. If you need a rugged, low-cost, quickly installable solution to adapt receiver size while keeping compatibility with industry-standard hitch pins, this sleeve delivers a practical option—just confirm receiver dimensions and hitch ratings before use.
