Product Information

AMP RESEARCH BEDXTENDER HD SPORT BED EXTENDER

AMP Research’s BedXTender HD Sport offers truck owners with tonneau covers the extra clearance sometimes needed to still get that additional 2 feet of cargo space for big things like motorcycles, lumber, tools, sports equipment and the like – as well as the ability to flip it forward to contain smaller things like groceries or gear.

  • Dramatically extends cargo capability of truck bed – up to 2 feet
  • Simply flips forward or backward to extend or contain cargo area
  • Great for hauling motorcycles, lumber, contractor tools and sports gear
  • V-shape design gives extra clearance you need for some tonneau cover rails

AMP Research, known for their superior engineering and design of aftermarket truck products that improve the vehicle’s functionality, get enthusiasts noticed for all the right reasons.
