2500 4wd always pulls to right.

Hey man, I'm on here to learn more about my truck. Some of us have less experience (myself) and others have more. Your post did nothing to educate and instead belittled me. Try to be more productive in this community and help spread your depth of knowledge. More folks will appreciate you.

Without derailing this thread, why are steering stabilizers useless then if the truck already comes with one?

Nobody belittled you. Though you apparently didn't bother reading the OP and the ad copy of the item you linked.
OP: truck pulls to the right
Ad copy: Our device corrects pull to the left.

Conclusion: That's the opposite problem from what the OP has.
You shouldn't attack @Rockcrawlindude for pointing out something you should have figured out for yourself.
