Curt 45785 Receiver Tube Adapter, 1-1/4" to 2" Shank, 6-1/4" Extension

Converts a 1-1/4" receiver tube opening to fit a 2" shank, extending clearance by 6-1/4" for a bike rack, cargo carrier, or spare tire. Rated for accessory tongue weight only.

Why Choose the Curt 45785 Hitch Extender?

Curt hitch adapters can be used for many different purposes when hitching up a trailer or accessory. Whether a shank is too small or too large to fit into a receiver tube, a Curt adapter can make up the difference. This particular adapter converts a 1-1/4" x 1-1/4" receiver tube opening to a 2" x 2" opening, letting you use a 2" shank accessory on a smaller receiver.

It installs easily and provides 6-1/4" of extra clearance, useful for a bumper, spare tire, bike rack, or cargo carrier that would otherwise sit too close to the vehicle. Each unit is CNC-formed, robotically welded, and mechanically descaled for a precise fit, then finished in a durable black powder coat for rust, chip, and UV resistance.

🚫 Not Rated for Towing

This adapter carries a tongue weight capacity of 350 lbs but is not intended for towing use to pull any amount of gross trailer weight. It's designed for hitch-mounted accessories like bike racks, cargo carriers, or spare tire mounts, not for connecting a ball mount and trailer. A hitch pin is also not included and must be purchased separately — a buyer review notes this is a notable omission at this price point, and a hitch tightener or stabilizer is recommended since the fit isn't perfectly snug.
