The marketing Order Guide stated that on units equipped with Ambulance & Wrecker packages, customers would get up to 7000 lb front spring FGAWR. The front coil springs were built to match the FGAWR labels on these units. The customer did not receive the front coil spring capability they were expecting based on the data in the marketing Order Guide and their reserve capacity might be lower than expected.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10201083-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10201083-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10201083","components":[{"id":"equipment","name":"Equipment and accessories","parent":null},{"id":"suspension","name":"Suspension","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"F-350 SD","year_from":2020,"year_to":2021,"match":"base","vehicle_ids":["2020_ford_f-350","2021_ford_f-350"]},{"make":"FORD","model":"F-450 SD","year_from":2020,"year_to":2021,"match":"base","vehicle_ids":["2020_ford_f-450","2021_ford_f-450"]},{"make":"FORD","model":"F-550 SD","year_from":2020,"year_to":2021,"match":"base","vehicle_ids":["2020_ford_f-550","2021_ford_f-550"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
