Slack Latch Sheave / Pulley for Rotary and Forward Lift 4-Post Locks – FC553-21Y (1/2″ Cable)
The slack latch sheave is a safety-critical component installed at all four corners of many 4-post automotive lifts. Replace this pulley when the plastic shell is cracked, grooved, or when cable fraying is observed at the latch corner. Before ordering, you need the FC553-21 (no “Y” suffix); (2) your lift model appears in the fitment list below; and (3) your latch style uses the small corner sheave. This is an aftermarket replacement designed to meet or exceed OEM specifications.
