CURT class 3 trailer hitches are designed, built and tested to accommodate a wide variety of towing applications. They are used on everything from full-size cars, vans and crossovers to light-duty pickup trucks and SUVs. Class 3 trailer hitches are perfect for towing fishing boat trailers, popup campers, ATV trailers, utility trailers and much more. They are also ideal for adding storage space to your vehicle with a hitch-mounted cargo carrier or bike rack (NOTE: Never exceed the lowest-rated towing component). Each CURT class 3 hitch is engineered to fit on a specific vehicle. If you own a vehicle with a trailer hitch, you know how quickly the receiver tube can get built up with dirt, debris and road grime. It does not take long before inserting a ball mount or hitch-mounted accessory into your trailer hitch becomes more difficult than it should ever have to be. With enough time and moisture exposure, the inside of a receiver tube can become seized up with rust, making it very difficult to use. Keep your trailer hitchs receiver tube clean and protected when not towing with one of CURTs attractive and durable tube covers. This CURT 2" x 2" receiver tube cover is constructed from quality rubber and mounts on your trailer hitch with a friction fit, meaning no hitch pin or clip is required.
