    • Extang is the leader in sales of "NO damage to your truck" Tonno covers. Extang is driven by outstanding quality and excellence in engineering design. Extang works with bed liners however there are a couple of additional steps needed to make our tonnos compatible with them. If you have an under-the-rail liner, you may need small rubber shims to help lift our tonno cover over your tailgate protector. If you have an over- the-rail bed liner, you will need to notch your bed liner so our clamps can go through the liner and wrap around the lip of your truck bed. Instructions for doing this are included with every kit.
