Installation Notes and Tips
Verify the vehicle year, model, and front axle application before installation. Inspect rotors, calipers, and pad hardware condition during brake service, and confirm the wear sensor routing matches the original setup. Because this pad set is listed for specific Dodge Ram 2500 and Ram 3500 front applications, match the part number SX459A and FMSI 7339A-D459 to the existing brake configuration before assembly.
