  • The installation of this pack will affect the truck's load carrying characteristics when the factory overload is removed. The owner will notice more squat in the rear when carrying heavy loads. If large loads are frequently hauled, we suggest adding some form of airbag kit in conjunction with this kit for optimum ride and load carrying characteristics.
