This is a f insulator from GM, factory part number 86542268. It is catalogued under Brackets & Supports > Mounts & Insulators.

• Torque figures belong to the fastener and the joint rather than to the part, so the factory procedure is the reference rather than a general rule.
• A part that fails early usually points at an installation fault or a worn component nearby rather than at the part itself.
• Where a diagram shows several similar items on one assembly, the difference between them is normally length, shoulder or handedness.

Corrosion at a mounting face is worth cleaning back before fitting anything new, because a part that sits on scale will work loose. Where a bracket also earths a component, the mounting surface needs to be clean metal or the circuit will be intermittent.

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. Ships from our US warehouse in one to two business days, free over $59.
