My truck comes with a pre-fab liner. Will the Black Armour® mat still fit?

Yes, Black Armour^® mats are designed to fit over a truck’s factory installed prefab liner.  The Universal Fit Bed Mat fits most short box and crew cab truck beds. For a truly custom fit, select the Custom Fit Mat for your specific make and model. Note that Custom Fit mats are available for Ford, Chevy, GMC, Dodge, and Toyota trucks with options for 5.5 foot, 6.5 foot or 8 foot beds.
