Not a dumb question at all. I added front and rear.
The front was a universal fit. I didn't realize a factory one would have slid right into place with no hole drilling. It helped vs a friend who has same truck with none.
The rear is trickier. Its looks a little funky, but it made as much of a difference the font made to stop the rolling in corners. Its not a sports car, but you don't feel like you're going to flip over in corners.
