Performance Accessories products are designed to fit new condition stock vehicles. Any product use on a vehicle other than that specifically listed in the Application Guide will result in difficulty of installation, possible damage to the vehicle, and will void all Performance Accessories product warranties. For some applications, extensive modification and some welding are involved. As such, we recommend installation be performed by an experienced installer and welding be accomplished by a certified welder. If larger tires are installed in conjunction with a body lift kit or a shackle lift kit, we recommend the installation of heavy-duty shock absorbers. Before combining a body lift with a suspension lift, consult an installation professional to see how this will affect your specific vehicle.
