Fifth Wheel Snap Ring

The fifth wheel king plate snap ring is a small but critical retention component designed to lock into a machined groove and help keep king plate-related parts securely seated. In heavy-duty towing, constant vibration, road shock, and frequent coupling cycles can cause wear or looseness over time—making a properly fitting snap ring essential for maintaining correct assembly position.

Replacing a stretched, bent, or corroded snap ring helps reduce excess play, support consistent coupling feel, and prevent components from shifting during service or operation.

Ideal for: repairs, rebuilds, and preventative maintenance.
Fitment note: Confirm ring diameter, thickness, and style match your application and groove for proper seating and retention.
