Truck Bed Compatibility and Measurement
Accurate measurement of your truck bed is essential to ensure proper fitment of the UnderCover Elite LX Tonneau Cover. This cover is specifically designed for 2021 - 2025 Ford F-150 models with a 5' 7" (67.1") bed.
To measure your truck bed, open the tailgate and use a tape measure to determine the length of the bed floor from the bulkhead (front wall of the bed) to the inside edge of the tailgate. Round your measurement to the nearest inch. For example, a measurement of 67.1 inches should be rounded to 67 inches, which corresponds to a 5' 7" bed.
