Why should you add a Leveling Kit to your Chevy Avalanche? Kits will re-index the height of the front of your truck and will provide you with a leveled vehicle. By having a leveled vehicle you will have quality handling. Kits will also allow for larger tires and will help with eliminating the nose down look that you would normally see in most trucks. All Rough Country, Tuff Country, ReadyLift and Daystar kits are custom made for your Avalanche application.
