• Gas Pressurized: Charged with nitrogen gas to 150 PSI to reduce air-to-oil foaming and prevent damping fade under heavy use.
• All-Weather Performance: The large twin-tube body is filled with specialized fluid capable of withstanding internal temperatures from -40 to 248°F.
• Protection Included: Comes equipped with a polyvinyl protective boot and durable rubber bushings to absorb road vibrations.
