CURT MANUFACTURING, LLC. part description

No matter what you are towing, CURT towing equipment is intended to get you from point A to point B and to have peace of mind while doing so. Our hitch extenders are no exception. 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.This CURT hitch extension is designed to fit a 1 1/4" x 1 1/4" receiver tube opening. It extends the receiver by 7", though it is not intended for towing a trailer. The tongue weight capacity is limited to the capacity of the hitch. CURT hitch extenders, like our ball mounts, trailer hitches and other made-in-USA quality products, are crafted to be durable and dependable. In addition to the strong steel construction and precise welding, our trailer hitch extenders receive a gloss black powder coat for ongoing prevention of rust, chipping and UV damage.

  • Extends receiver tube by 10" for added clearance
  • CNC-formed, robotically welded and mechanically descaled for a perfect fit
  • Protected by a durable powder coat finish
