Collection: 2015-2019 Chevy Silverado 3500HD Bed Extenders

Every bed extender in this collection fits 2015-2019 Chevy Silverado 3500HD trucks. Options cover both 6'6" standard and 8' long beds, with fold-down and swing-out styles from brands like AMP Research BedXtender HD and Rough Country.

Do I need to drill holes to install a bed extender? No. These extenders mount to existing stake pocket holes in the bed rails, so installation is bolt-on with basic hand tools in about 30 minutes.

Verified fitment for your 3500HD -- no guesswork, no returns.
