Step bar filler and tailgate damper
 

Does anyone know what the part number is for the factory step bar fillers are in black color for
standard length crew cab?
also the part number for a 2021 f350 tailgate damper kit

I'm almost certain HC3Z-99406A10-A is the part number for the tailgate damper. But check to see.

May I ask what trim level you have and do you have the step/assist tailgate? I'm wondering if I'll be ordering a damper for my new truck when it arrives.

I have the step in the tailgate but it doesn’t have the dampener. Mine is a lariat with the black out package but I only got the vale package not the ultimate

Then I will probably need a damper... :)

do you mean these?

I have them and really not sure of the purpose they serve other then to hide the frame behind…. Or maybe to gain some mpg’s???
