Retainer – GM (19404513)

The retainer here is the GM part, numbered 19404513.

It is catalogued under Nuts & Washers > Rings & Retainers.

Match thread size and pitch to the fastener, then match the type to the joint. That order avoids most returns. Flange nuts distribute clamping load without a washer, so a plain nut at the same torque will mark the component.

In stock and sent from the US in one to two business days, free delivery over $59. The part number is the thing to verify. Where the old part carries no legible number, a VIN and a photograph are enough for us to identify it.
