Collection: 2007-2014 GMC Sierra 2500HD Bed Extenders

These bed extenders fit 2007-2014 GMC Sierra 2500HD trucks with 6.5ft and 8ft beds. Choose from AMP Research BedXTender HD Sport and Max models in silver or black, plus tailgate-mounted flip-down options that add roughly two feet of usable cargo length.

Do I need to drill my bed to install one? No. AMP Research extenders clamp to the stake pockets using the included hardware, so installation is bolt-on in about 30 minutes with no drilling required.

Verified fitment for your Sierra 2500HD, no guesswork.
