777C-10066 or 777C10066 is a Fabco wave spring, a genuine Fabco part from Pro Gear and Transmission. The size call-out on the part reads 4.13X3.60X.200/.109-65.
A wave spring is a flat-wire compression spring with waves formed into each coil, so it pushes back along its axis while taking up very little room. It can deliver the force of a round-wire coil spring in a much shorter stack. Fatigue is the main concern when a wave spring cycles hard, so one that has lost its force is due for replacement. Call us to confirm proper fit for your application.
