Application and installation

Diesel engines only. For trucks with the factory rear overload leaf and without a factory rear sway bar. Confirm this configuration before ordering.

The factory rear overload leaf is retained in this configuration.

The manufacturer eight-inch system configuration retains the factory rear blocks with the supplied five-inch blocks and add-a-leaves. Follow the linked manufacturer instructions for the exact vehicle configuration and component placement.

Manufacturer wheel guidance, with minor trimming: 355/65R18 tires on 18x9.5 wheels with 4.75-inch backspacing; or 37/13.50R20 tires on 20x10 wheels with 4.5-inch backspacing. Check clearance on the actual vehicle.

Professional installation and alignment are required.
