About this item
Product details
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. Our adapters are built with exceptional strength and designed to be precisely fitted for their application. We 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. This specialized CURT receiver adapter converts a 2-1/2" x 2-1/2" receiver tube opening to a 2" x 2" opening. It offers a gross trailer weight capacity of 4,500 lbs. and a tongue weight capacity of 450 lbs., and when combined with a weight distribution hitch, it offers 6,000 lbs. GTW and 600 lbs. TW. It also has the option to be cut down from its 34" length to 24", increasing its weight carrying capacity to 6,000 lbs. and its tongue weight to 600 lbs. When combined with a weight distribution hitch, the 24" length maxes out at 8,000 lbs. GTW and 800 lbs. TW. This hitch adapter also comes with integrated safety chain loops and an electrical bracket. All CURT adapters are constructed using our quality manufacturing processes. We 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, we give it a durable gloss black powder coat finish to ensure it has excellent rust, chip and UV resistance.
- Adapts a 2-1/2" trailer hitch receiver tube opening to fit a 2" shank
- Extends receiver tube by 24" or 34" for added clearance
- Can be cut down from 34" to 24"

Hitch adapters
On my truck I had to make some modifications with a grinder for the 2-in adapter to fit. Other than that works like a charm

I bought a new camper
I bought a new camper with a 2" receiver on the back. I had a bike rack that was 1-1/4 receiver. I contemplated buying a new bike rack for the camper but it would have cost over $250.00. I found Realtruck on the internet and found out they had an adaptor which was the Curt receiver adaptor. Works and fit very good.
