This is a Professional Grade Wheel Alignment Camber Bolt Kit for your 1999-2004 Ford SVT Lightning. After the installation of a lowering kit, a vehicle's alignment should always be checked. Once a vehicle is lowered, wheel camber may become excessively negative, meaning the top of the tire is angled inward (toward the center of the vehicle). While some negative camber aids in improving traction and road adhesion, too much can result in compromised handling and accelerated tire wear. These bolts will help get your truck properly aligned and get you back on the road in no time!
