TOPBEE Trailer Hitch Adapter 2.5" to 2" Reducer Sleeve — Carbon Steel, Lip-Lock Design with 5/8" Pin

The TOPBEE 2-1/2" to 2" Trailer Hitch Adapter is a heavy-duty carbon steel sleeve that converts a 2.5" receiver into a 2" hitch so you can use smaller accessories securely.

When your vehicle and accessory sizes don’t match, towing stops being convenient and starts costing time. The TOPBEE hitch reducer sleeve restores compatibility between Class V 2.5" receivers and common 2" Class III/IV accessories—bike racks, cargo carriers, ball mounts—so you can get back on the road without guessing whether your gear will fit. Built to resist corrosion and vibration, it ships with a 5/8" pin and clip for immediate installation.

How does this adapter keep accessories secure while towing?

The TOPBEE adapter uses a lip-lock geometry that nests in the 2.5" receiver to prevent forward/backward movement and reduce rattle. Combined with the included 5/8" pin and clip, the sleeve makes a tight, reliable connection between vehicle and accessory without modifications.

• Lip-lock design seats the sleeve firmly in the receiver for a snug fit.
• 5/8" pin hole positioned for standard hitch pins or locks (pin included).
• Powder-coated carbon steel reduces wear and resists road corrosion.

How simple is installation and what comes in the box?
