TOPTOW Trailer Hitch Adapter 3" to 2.5" & 2.5" to 2" — Carbon Steel with 5/8" Pin Included

The TOPTOW 64027HP trailer hitch adapter converts a 3" receiver to 2.5" and a 2.5" receiver to 2" quickly and securely, and comes with a 5/8" pin and clip for immediate use.

This two-stage hitch reducer is designed to help owners of Class V pickup hitches use smaller ball mounts, bike racks, or cargo carriers intended for 2.5" or 2" receivers. Built from carbon steel with a black powder coat, the adapter focuses on simple fit, anti-slip placement and compatibility with standard 5/8" hitch pins. It does not change the towing limits of your vehicle—use it only within the rated capacities of your receiver and accessories.

How does this adapter solve mismatched receiver sizes?

The TOPTOW adapter slips into a larger receiver and provides a smaller-diameter opening for accessories designed for 2.5" or 2" receivers. A formed lip on the sleeve helps it seat against the tube edge so it stays positioned during connection and use.

• Converts 3" down to 2.5", and 2.5" down to 2" without welding or modification.
• Internal lip prevents the sleeve from sliding too far into the receiver.
• Includes a 5/8" pin and clip so you can secure accessories immediately.
• Works with common Class III/IV/V accessories when used within rated limits.

Is this adapter strong and corrosion resistant?

Yes — the sleeve is formed from heavy-gauge carbon steel and finished with a black powder coat to resist surface rust and daily wear. Durability depends on proper use within the towing and tongue-weight ratings of your hitch and accessory.

• Carbon steel construction for strength under typical towing loads.
• Black powder-coated finish for improved corrosion protection.
• No plated or stainless option in this model—inspect periodically for wear.
• Use manufacturer-rated pins, locks, and safety chains as required by law.

How does the included pin and clip work with the adapter?

The adapter accepts a standard 5/8" hitch pin through its reinforced hole so you can pin a ball mount or accessory in place. The supplied pin and clip fit the adapter's hole and give immediate securing capability without additional hardware.

• Universal 5/8" hole spacing compatible with common hitch pins and locks.
• Pin length allows clearance up to about 3" from pin center to sleeve flange.
• Pin and clip are included, so no separate purchase is necessary for basic use.
• For locking security, use a hitch lock rated for 5/8" pins (not included).

Will this adapter affect towing capacity or safe operation?

The adapter does not increase a vehicle’s towing capacity; it only changes receiver size. Always follow your vehicle and hitch manufacturer ratings and limits. Inspect the adapter and all connections before each trip.

• Adapter is limited by the lowest-rated component in the towing setup.
• Do not exceed receiver, hitch ball, or vehicle manufacturer ratings.
• Verify tongue weight and load distribution when using different accessories.
• Regularly check for corrosion, cracks, or deformation and replace if damaged.

Who is this for: TOPTOW's 64027HP adapter is aimed at owners of full-size pickups or vehicles with 3" or 2.5" receivers who need to use smaller-diameter accessories—such as bike racks, cargo carriers, or ball mounts—without altering the vehicle. It's a practical solution for tradespeople, outdoor enthusiasts, or anyone juggling different hitch-mounted gear who wants a rugged, ready-to-install sleeve and basic securing hardware.
