Dorman - OE Solutions Door Check P/N:924-924
Keep a heavy truck door from swinging too wide with this Dorman door check strap, part number 924-5401 from the HD Solutions line. It is designed to limit how far the door opens and help hold it in its open position. It fits many heavy-duty trucks, among them the 2003-2005 Peterbilt 379, 1987-1996 Peterbilt 357 and 1987-1996 Peterbilt 377. See the "Vehicles it fits" section for the full list.
Dorman lists this part as a heavy-duty door check kit, intended to take the place of an original strap that has failed.
A door that swings open farther than it should, will not stay open, or pops and clunks as it moves may mean the check strap needs replacing. Inspect the door and hinges first, because other worn parts can cause similar symptoms.
