Incorrect camber adjustment, as well as sudden and extreme changes in alignment cam position, can negatively affect the performance of your vehicle and cause damage to ball joints, control arms, spindles, axles, hubs, wheels, and tires. Precision CNC Laser Cut from 3/16" Steel and designed with seven alignment holes to keep the alignment locked in place, our adjusting kit allows for +/-1.5 degrees of Camber and Caster adjustment, in 0.5 degrees increments, helping you to regain proper alignment on your lifted vehicle, prevent damage to steering and suspension parts, and improve your vehicle safety. Note:?*An alignment is always recommended after altering the height of your vehicle.
