Replacement front and rear bumper dimensions

I'm looked for some replacement front and rear bumpers that give a better approach/departure angle, but without making the overall length of the truck longer. Many of the aftermarket (front) bumpers have something like a bull bar that obviously sticks out further than stock, but for bumpers that don't have something so obvious, I'm having a hard time finding dimensions that clarify how much further out they stick than the stock bumper. I don't need a winch mount, light protection, etc., just a bumper that is more compact and durable than the stock plastic front end. Any suggestions on what I should look at?
