CURT hitch adapters can be used for many different purposes when hitching up a trailer. Whether a ball mount shank is too small or too large to fit into a receiver tube, a CURT adapter can make up the difference. Their adapters are built with exceptional strength and designed to be precisely fitted for their application. They carry trailer hitch adapters to accommodate both receiver tube openings and shanks of 1-1/4", 2" and 2-1/2" dimensions. CURT adapters also come in various lengths to allow more clearance for a cargo carrier, bike rake or spare tire.
The 2" x 2" receiver tube opening to a 1-1/4" x 1-1/4" opening adapter/extender installs easily and provides 4" of extra clearance for a bumper or spare tire. It has a gross trailer weight capacity of 3,500 lbs. and a tongue weight capacity of 350 lbs.
The 1-1/4" x 1-1/4" receiver tube opening to a 2" x 2" opening adapter/extender installs easily and provides 10" of extra clearance for a bumper or spare tire. It has a tongue weight capacity of 350 lbs. but is not intended for towing use to pull any amount of gross trailer weight.
All CURT adapters are constructed using their quality manufacturing processes. They CNC-form each unit, weld it together using advanced robotic systems and then mechanically descale every surface to make each adapter smooth to accept a finishing coat. To finish off this adapter, they give it a durable black powder coat finish to ensure it has excellent rust, chip and UV resistance.
