Be advied that any modifications to the suspension may void that area/aspect of your warranty and maybe more depending on the dealership.

Just the other day we had a guy with a 2010 Titan who did a serious suspension lift on it, the truck had 12k miles and it broke an upper control arm. He wanted it covered by warranty but due to his altering of the vehicle he had to pay.

Do what you want, I'm just giving you a heads up
