This snap ring is a circular metal fastener that fits into a groove on a shaft or inside a housing bore to keep components like gears, bearings, or seals from moving axially.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
In heavy-duty truck applications, it is commonly found in power take-off (PTO) units, transmission shafts, and hydraulic pumps. You replace it when the ring becomes deformed, corroded, or broken, or whenever you disassemble a shaft assembly to ensure secure retention.
