How can I improve my 2018 Silverado suspension?

If you are looking to achieve a mild lift, a leveling kit or 4-inch lift kit is a great option. A leveling kit raises the front of the truck to match the height of the back, which in turn “levels it out.” Most people who throw a leveling kit on their truck experience an additional 2 inches of height in the front. Typically, a leveling kit will allow for 33” tires to fit comfortably on your truck. A lift kit will deliver more height, better ground clearance, and look more aggressive overall. When it comes to lift kits, 4-inch and 6-inch lift kits are among the most popular choices for a 2018 Silverado 1500, allowing for an oversized 35”+ off-road tire to fit in most cases. If you’re looking to spend some big bucks for the best performance possible, look into getting a full coilover kit.
