The Duraliner Under Rail Bed Liner stops beneath the rail lip, so the stock rail caps and stake pockets stay exposed for a tonneau cover, a truck cap, or a rack that clamps to the factory metal.\u003c\/p\u003e\n\u003cp\u003eUnder rail means the shell protects the bed floor, the sidewalls, and the front bulkhead, then stops short of capping the rails themselves. Duraliner builds this style for owners fitting a truck cap or tonneau cover, and it supports two-tier and compartmental loading. With the rails clear, the factory rail surface stays available for whatever you mount to it.\u003c\/p\u003e\n\u003cp\u003eDuraliner thermoforms the shell from black polyethylene and molds it to the contours of one specific bed, so it seats on the floor and up the sidewalls without drilling a single hole. The surface is smooth and skid resistant, so cargo stays put and the liner will not chew up what you haul. The walls carry a ribbed profile, and board holders are molded straight into the liner rather than bolted on afterward. Duraliner rates the liner at seven times more bed protection than a spray-on liner.\u003c\/p\u003e\n\n\u003ch2\u003eKey Benefits\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRails stay open.\u003c\/strong\u003e The liner ends below the rail lip, leaving the factory rail surface clear for tonneau clamps, cap clamps, rack feet, and stake pocket accessories.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCargo stops sliding.\u003c\/strong\u003e The smooth skid resistant floor holds toolboxes, lumber, and loose gear in place instead of letting them travel on every corner.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRibbed walls take the hit.\u003c\/strong\u003e The rib pattern guards against dents and scrapes from shifting loads, so the damage lands on the polyethylene instead of your sheet metal.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWater drains out.\u003c\/strong\u003e The custom molded shape channels rain and washdown water away from the bed floor rather than trapping it against painted steel.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwo-tier and compartmental loading on most applications.\u003c\/strong\u003e Where the part number includes molded-in board holders, you can run cross boards to stack a second level or split the bed into sections for separate loads.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShop chemicals wipe off.\u003c\/strong\u003e The polyethylene resists gasoline, oil, and most chemicals, and the UV protected finish holds its deep black through years of sun.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSurface Fit\u003c\/h2\u003e\n\u003cp\u003eEach part number is molded for one bed length on one truck generation. The liner follows the wheel well bulges, the front bulkhead, and the tailgate opening, so there are no large gaps for gravel and grit to collect behind.\u003c\/p\u003e\n\u003cp\u003eBecause the shell ends below the rail lip, the factory clamping surface stays exactly as the truck left the plant. Tonneau clamps, cap clamps, and rack feet land on bare rail instead of on plastic, and nothing about the rail height or profile changes when the liner goes in.\u003c\/p\u003e\n\u003cp\u003eTie-down cutouts vary by application. Most models include tie down hole caps in the kit to close off the openings you are not using, and depending on the truck you may also get pocket detents, horizontal board holders, or vertical board holder slots.

The same truck is often sold in two or three bed configurations, and each one takes a different liner.\u003c\/p\u003e\n\u003cp\u003eIf you are not certain which bed you have, chat or message the team before you order and we will confirm year, make, model, and bed size with you.\u003c\/p\u003e\n\n\u003cp\u003eRunning a tonneau cover or a cap on the truck, or planning to add one later? Under rail is the style that keeps the factory rail clear for it.
