Will New Struts Raise the Front End?

Also false. Shocks/struts don't do anything to change ride height unless they have adjustable perches. All they do is dampen the amount of jounce and rebound caused by the springs when going over bumps.

Can struts change ride height?

STRUTS/SHOCKS DO NOT AFFECT RIDE HEIGHT.

Do new struts lift your truck?

While new or pressurized shocks can lift your truck about half an inch, they do so because of the added pressure inside them. Let's remember that the shock's function is to keep the tires on the ground. So, it's expected for them to “push” up the truck. But, over time, this pressure decreases.
