The CURT reducer sleeve set includes two reducer sleeves that adapt a 3" receiver tube opening to fit a 2-1/2" or 2" shank. The adapter sleeves install easily and are compatible with virtually any 3" hitch. The smaller sleeve can also be used in a 2-1/2" receiver tube opening, adapting it for a 2" shank. The gross trailer weight capacity and tongue weight capacity of this set are limited to the rating of the hitch. To finish off this reducer sleeve set, it comes with a highly durable carbide black powder coat finish, ensuring excellent rust, chip and UV resistance.
