Locking Hitch Pin Dust Cover Replacement

This is the replacement rubber cap that snaps over the lock end of a Equal-i-zer locking hitch pin. It is a small part with one job: keeping water, road grit and winter salt out of the keyway so the barrel lock keeps turning smoothly year after year.

The cover is molded from weather-resistant rubber and sized to fit snugly over the lock cylinder on the 5/8″ locking hitch pin, with a keyhole flap that lifts out of the way when you need the key. The originals occasionally tear, dry out, or get pulled off in a car wash; a missing cover is the most common reason a locking pin seizes or will not accept its key.

Replacing it takes seconds and costs far less than a new lock. If your cover is cracked or gone, fit a new one before the next trip and keep a spare in the glovebox.

Specifications

  • Fits: Fastway® 5/8″ barrel-key locking hitch pins — 86-00-3050 (2″ receiver) and 86-00-3160 (2-1/2″ receiver) — and the lock-pin halves of the Dual Lock Packs 86-00-3660, 86-00-3685 and 86-00-4200 (verify fitment list)
  • Material: weather-resistant molded rubber
  • Function: seals the keyway of the barrel lock against water, dirt, road salt and freezing; works with the lock’s O-ring to keep the cylinder turning freely
  • Install: push-fit over the lock end of the pin, no tools
  • Quantity: 1 cover (verify)
  • Maintenance: keep the cover on whenever the key is out; if the lock starts to feel gritty, pull the cover, flush the cylinder with a dry lubricant such as graphite or a PTFE spray, and refit
  • Replacement: replace when cracked, hardened, torn or missing. A locking pin run without its cover is the most common cause of a seized cylinder and a cut-off lock
