Measure Your Truck Bed for a Tonneau Cover

Before you add your drop-in bed liner to your truck bed, get yourself a WeatherTech UnderLiner bed liner pad to give your truck the ultimate protection. The UnderLiner will protect your beds paint from the rough texture of the drop-in bed mat.

Built to be a buffer against the rubbing of your drop-in liner, the WeatherTech UnderLiner sits right between your truck bed and bed liner. UnderLiner pads are digitally designed for that perfect wall-to-wall fit in your pickup. The .065" thick semi-soft design provides excellent protection that won't throw off the fit of your bed liner.

Installing your UnderLiner truck bed mat is a breeze. Just lay the UnderLiner in your bed down, install your drop-in bed liner on top of it, and you are ready to start hauling whatever your heart desirers. What are you waiting for? Order your own WeatherTech UnderLiner bed liner today!
