Important Notes

• If the steering gear box has been changed and the sector shaft diameter measures approximately 1-1/2"–1-5/8", part number ZOND8404 is also required.
• This truck was produced with rear axles of differing diameters. Measure the diameter of your rear axle before selecting a kit configuration.
• Although rare, if front driveline vibration occurs after installation, install the optional transfer case indexing ring.
• This kit is not designed for dually models, but may be adapted. Contact customer support for assistance.
• Gas models may require modification to the front exhaust crossover pipe on the driver side when using the transfer case indexing ring.
• Two-piece rear drive shaft: Add a carrier bearing drop kit to reduce post-lift driveline angles and avoid or eliminate driveshaft vibration.
• Adding larger-than-stock wheels: Add front bumper spacers for additional clearance, as some wheel and tire combinations may not fully clear the bumper's stock location.
