When you have spacing issues with your hitch mounted accessories such as a bike rack or cargo carrier, or you need to give your ball mount and trailer coupler a little extra room, a CURT hitch extender can help. Hitch extensions are simply receiver tubes that insert into your trailer hitch to add a certain amount of clearance for your vehicle's bumper or spare tire mounted on the back. A hitch extender makes it very easy to give your tow load the room that it requires and helps protect your vehicle from scuffs, scratches and even dents. It not only extends the receiver by 8 Inch but also allows you to simultaneously tow a trailer and mount a hitch mounted bike rack or cargo. It has a gross trailer weight capacity of 3,500 Pound and tongue weight capacity of 350 Pound. The top receiver is not intended for towing a trailer. In addition to the strong steel construction and precise welding, our trailer hitch extenders receive a gloss black powder coat for on going prevention of rust, chipping and UV damage.
