Service bulletin GB2021003
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
Ford Motor Co. has informed IMT of stress points that could cause a crack in the frame rail behind the cab on certain MY 2017–2020 Ford F550 chassis. Because of the increased height due to Ford’s reinforcement, IMT has created a field retro installation kit, part number 51728356. Two (2) new front mounting brackets and hardware will be included in kit 51728356 which will solve the increased height issue.
