Do you know the socket size to remove the bump stops from my 2018 F-53 ford chassie? Thank you. Can’t seem to find the correct socket to use.

Hey Patrick. I looked on Ford's replacement part website and the factory bump stops on a 2018 F-53 come with 3/4" nuts so I would try that. If you're installing the SumoSprings Rebel Custom Helper Springs item # SSF-170-40-2 you are going to need to reuse the hardware from the factory bump stop.
The SumoSprings item # SSF-170-40-2 are confirmed to fit the following models of the 2018 Coachmen Mirada Motorhome:
29FW
32SS
35BH
35KB
35LS
What size sockets have you already tried to use or have you not gotten under there yet?
