What Proposition 65 Is

Proposition 65, officially the Safe Drinking Water and Toxic Enforcement Act of 1986, is a California law.

It requires the State of California to publish a list of chemicals known to the state to cause cancer, birth defects, or other reproductive harm, and it requires a clear and reasonable warning before a covered exposure.

The list is maintained by California's Office of Environmental Health Hazard Assessment (OEHHA) and is updated at least once a year.

Why You See This Warning

A Proposition 65 warning does not mean a product is unsafe, defective, or in violation of any safety standard.

It means the product may expose you to a listed chemical at a level that requires a warning under California law. Warnings are common on automotive parts because of the metals and materials used in their manufacture.

Products sold outside California may carry the same warning, because manufacturers commonly label an entire production run rather than a California-only version.

Where the Warning Appears

The Proposition 65 warning is shown on the product page of each affected item, below the product description, so it is visible before purchase.

The exact wording differs from product to product. Where a manufacturer identifies specific chemicals, we display that manufacturer's wording rather than a generic notice.

We also submit the same warning to shopping platforms through their dedicated consumer notice field, so the notice you see here matches the notice shown elsewhere.

Chemicals Commonly Named on Automotive Parts

Warnings on the parts we sell most often name one or more of the following:

• Lead and lead compounds
• Nickel (metallic)
• Chromium (hexavalent compounds)

Brake, suspension, exhaust, engine and wheel components are the categories where these warnings appear most frequently.

Reducing Your Exposure

General handling practices that reduce exposure when installing or servicing automotive parts:

• Wash your hands after handling parts, and before eating or drinking
• Avoid breathing dust when cleaning brake, clutch or engine components
• Work in a well-ventilated area
• Wear gloves and eye protection where the installation instructions call for them
• Follow the manufacturer's installation and safety instructions
