Question:
I would like to replace 4 plastic grease covers on a 2012 TandB Welding trailer with tandem duals. The existing grease covers are marked Dexter 21 88. I would like to switch to aluminum grease covers. Which models are a match for the Dexter 21 88 plastic covers? Thanks Dennis

To replace your Dexter 21 88 grease covers with some aluminum ones you will need the Dexter Fortress Threaded Aluminum Oil Cap item # DX87CR. They have the same thread pattern. This are sold individually.
