Description - Rear of vehicle sits too high to allow hook up to a fifth-wheel
trailer. This bulletin applies to 2500 and 3500 4x4s. The curb hight
lowering package is designed to reduce the rear spring spacer block by
1 7/8 inch, which will lower the rear of the vehicle by several inches
proving clearance so that most customers can attach their fifth-wheel or
goose neck trailer to the trailer hitch turntable.
