Nope. We designed the DECKED system with spray-in bed liners in mind. We have taken into account the normal additional volume and created enough lateral space to accommodate a spray-in liner (unless your installer went crazy with the amount of material they added to your truck bed) you should be fine.

Note: some of our systems require that you replace the factory tie-down brackets. You will need to heat up the spray-in material, cut around the tie-down bracket and then peel the spray-in material away. It is recommended that you use a heat gun or hair dryer to warm the spray-in material. Once you have removed the bracket, you can install the new bracket that comes with your DECKED system.
