The BedRug Impact Mat is designed specifically for trucks that have an existing spray-in liner or no bed liner. The all new design has an integrated tailgate gap guard hinge that connects the bed piece to the tailgate piece. The TPO composite top layer construction offers a flat work surface, that is slip and skid resistant. The padded under layer provide dent and impact resistance while offering cushion for your knees while crawling around in your truck bed. The Impact Mat installs in minutes using hook and loop fasteners to install without the need to prep, sand or drill holes into your truck bed.\nIMPACT MAT FOR SPRAY-IN OR NO BED LINER 02-18 (19 CLASSIC) DODGE RAM 6ft.4 BED W/O RAMBOX (non 2500/3500 built after 2/23/13 with 5th wheel)\n2004-2005 Dodge Ram 1500 75.9 Bed; 2006-2010 Dodge Ram 1500 76.3 Bed Without RamBox; 2002-2003 Dodge Ram 1500 78.0 Bed; 2003-2005 Dodge Ram 2500 75.9 Bed; 2006-2010 Dodge Ram 2500 76.3 Bed Without RamBox; 2002 Dodge Ram 2500 78.0 Bed; 2003-2005 Dodge Ram 3500 75.9 Bed; 2006-2010 Dodge Ram 3500 76.3 Bed Without RamBox; 2011-2018 Ram 1500 76.3 Bed Without RamBox; 2019 Ram 1500 Classic 76.3 Bed Without RamBox; 2011-2018 Ram 2500 76.3 Bed Without RamBox; 2011-2018 Ram 3500 76.3 Bed Without RamBox
