PROPOSITION 65 WARNING EXPLANATION
JKS Manufacturing applies warning labels either on our product(s), the packaging containing our product(s) regarding CA Prop 65. This warning is part of our effort to comply with the California Safe Drinking Water and Toxic Enforcement Act of 1986 (known as “Proposition 65”). The warning does not mean that our products will necessarily cause cancer, birth defects, or other reproductive harm. While we believe our products are not harmful when used as designed, and we rely on our suppliers to help with this effort, we also provide these warnings to comply with Proposition 65.
What is California Proposition 65?
Proposition 65 is a far reaching law and applies to any company that operates in California, sells products in California, or manufactures products that may be sold in or brought into California. Proposition 65 requires warnings to accompany any product that contains or may contain any of the chemicals appearing on the list administered by California’s Office of Environmental Health Hazard Assessment (OEHHA), a part of the California Environmental Protection Agency. The current list can be found here: https://oehha.ca.gov/proposition-65/proposition-65-list
What This Means To You
While the proposition was created to protect drinking water sources from chemical contamination, the scope of the law has expanded over the years. It now includes over 900 chemicals and also pertains to (but is not limited to) exposure through touch, inhalation, ingestion, or skin contact.
The Prop 65 warning can now be found on products that may contain a small amount of over 900 chemicals or ingredients that the OEHHA lists as a carcinogen or reproductive toxicant. This includes compounds that are used in everyday life like vinyl, coatings, plastics, and much more.
Why has JKS Manufacturing decided to provide a warning?
Proposition 65 imposes strict penalties for noncompliance. While California establishes “safe harbor numbers” for listed chemicals, the costs of individually testing products that JKS Manufacturing sells and distributes is prohibitive (particularly when the list of chemicals is so expansive and subject to change on an annual basis).
As a result of the steep penalties and because there is no penalty for providing an unnecessary warning, JKS Manufacturing (like some other companies doing business in California) decided to provide the Proposition 65 notice out of an abundance of caution.

IFP design eliminates oil aeration Valved specifically for JSPEC systems. Direct bolt-in replacement.
The 2.0 Performance Series IFP shock has a predicable ride quality capable of handling the roughest road conditions.
Shock absorbers are an important part of your Jeep’s suspension system. JKS offers a range of custom-valved shocks to fit your budget and performance needs. JSPEC Series gas shocks feature affordable twin-tube design with custom valving for improved handling and ride quality on and off-road. Ride quality is tuned to work with large diameter all-terrain tires. For more aggressive off-road performance, step up to optional FOX shock absorbers. They feature IFP technology, aluminum bodies, heavy duty shafts and superior monotube valving for a better driving experience regardless of terrain.
JKS J-Rated Suspension Systems feature custom wound, progressive rate coil springs. That means the spring rate increases as the spring is compressed. You and your Jeep enjoy a plush ride during low load driving scenarios such as highway cruising with increased performance as each spring compresses. If you carry a significant amount of extra gear in your Jeep, some J-Rated suspension systems are available with optional high-rate coil springs to support the additional weight.
