JKS offers a wide range of Jeep-specific JSPEC and FOX shock absorbers and coil-overs to match your intended terrain use, driving style, and budget.
Also known as dampers, proper shock absorber design and valving are critical elements of high-performance Jeep suspension. Installing a suspension lift to accommodate larger wheels and tires requires longer shock absorbers or coil-overs. Mismatched shocks could destroy themselves by bottoming out or topping out due to improper travel. JKS understands shock travel and motion ratio as well as proper mounting.
Damper valving is equally critical. The JKS R and D team custom-tailors shock absorber valving to suit a number of variables including the increased “unsprung” weight of larger wheels and tires as well as the demands of off-road driving. On-road ride quality is equally important for the best possible driving experience.
All JKS and FOX shocks and coil-overs are made in the USA. Steel Body Shocks: JKS JSPEC shocks and FOX Adventure Series shocks | Aluminum Body Shocks: FOX 2.0 IFP Performance Series Shocks, FOX Performance Elite Shocks, FOX Factory Race Shocks.
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.

Choose your Coils?
PICKING THE RIGHT COIL SPRINGS
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.
