This change does not affect the ride height of your spec, it clarifies the ride height within the data code. For example, if a customer uses a 40,000# AirLiner suspension today with the 621-007(AirLiner High Position Ride Height) that spec will be updated to use 621-118 (7.9\" nominal ride height).","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10200687-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10200687-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10200687","components":[{"id":"suspension","name":"Suspension","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FREIGHTLINER","model":"CASCADIA","year_from":2022,"year_to":2022,"match":"exact","vehicle_ids":["2022_freightliner_cascadia"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
