Stud Kit – GM (19405942)

GM lists this stud kit under number 19405942. It is catalogued under Bolts & Screws > Studs.

• Three numbers decide fit on a bolt: thread diameter, thread pitch and length under the head. A fourth decides survival: the property class, which sets the torque it will take.
• A fractional size and a metric size can look alike at the head and be entirely different at the thread. Never substitute a hardware-store bolt for a suspension or driveline fastener.
• If the original fastener carries a marking, match the marking. If it carries none, match the factory part number instead.

Where the vehicle is close to a model-year change, the VIN is a more reliable guide than the registration date. A part that fails early usually points at an installation fault or a worn component nearby rather than at the part itself.

Worth checking against the original before fitting. If you cannot read the number, we can match it from the VIN. Handed to the carrier within one to two business days from our US warehouse, free over $59.
