Compliance Notice
California Proposition 65
What you need to know about chemical exposure in automotive & motorsport parts.
Official Warning
WARNING: This product can expose you to chemicals including lead, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
What is Proposition 65?
California's Proposition 65, officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986, requires businesses to provide warnings to Californians about significant exposures to chemicals that cause cancer, birth defects, or other reproductive harm.
These chemicals can be in the products that Californians purchase, in their homes or workplaces, or that are released into the environment. The list is maintained by the California Office of Environmental Health Hazard Assessment (OEHHA) and currently contains over 900 chemicals.
Why Do Our Products Carry This Warning?
Broad product range: Many automotive and motorsport parts — including metals, rubber components, lubricants, coatings, and adhesives — contain or may expose users to chemicals on the Proposition 65 list.
Transparency first: Rather than evaluate every product individually, we apply the warning broadly to ensure compliance and keep you informed. Seeing this warning does not necessarily mean a product is unsafe — it is a threshold disclosure, not a hazard declaration.
Exposure vs risk: A chemical being listed does not mean products containing it will cause cancer or reproductive harm at typical real-world exposure levels. Prop 65 thresholds are set far below levels that cause observable effects in laboratory studies.
