Leveling kits can impact your suspension, but the extent of the impact depends on the type of kit, the size of the kit, and how it's installed. When installed correctly, minor changes to a vehicle's suspension should not cause significant damage to day-to-day driving.  However, for off-roading, towing, carrying large cargo, and more aggressive driving, the suspension could negatively impact, causing increased wear and tear. Besides, it's rare, but leveling kits can cause increased wear on ball joints and reduce the overall life of a truck.
