Snap Ring and Retention Detail
The BS retention system on this yoke uses a standard snap ring seated in the output shaft groove. The groove geometry dictates which snap ring style is required -- do not substitute ISR hardware in an OSR groove or vice versa. Snap ring ejection under load is a catastrophic failure mode that can damage adjacent driveline components.
Through bore ID: 1.150" -- required clearance dimension for applications with internal shafts.
