The Hitch Receiver Extension with Step from Buyers Products provides more clearance between your vehicle and your trailer. This feature lets you install a bike rack that will clear your mounted spare tire, or simply allow you to add an step plate for easy access around your trailer assembly. The extension is available in 12 in. length and accepts all 2 in. hitch accessories. It features a cast steel collar and corrosion-resistant black powder coating. bImportant: A hitch extension will reduce your towing capacity by one-third./b
