Fitment & Compatibility

Match the actual 2004–2008 new-body six-lug 4WD truck against the applications below. Seven-lug versions and the 2004 Heritage do not fit. Follow DS1131 for hub and hydraulic installation, then verify the complete 20-inch wheel profile rather than relying on wheel diameter alone.

Check the application-specific restrictions for F-150. A shared model name does not replace the exact year and brake/suspension configuration. Use the fitment table below to confirm year, model, trim and brake or suspension options.

PMB Performance brings over 20 years of parts and fitment experience. Send the vehicle details and installed brake/suspension configuration if you need help checking this package.

Check the Installation instructions for the full assembly and wheel-clearance requirements.
