The JRZ damper is an advanced development in high performance shock absorbers. The JRZ RS is a high gas pressure double adjustable twin tube damper. without the use of an external reservoir. Applying our race winning technology. JRZ designed the JRZ RS to give precise chassis control when driving on track and ultimate comfort for daily driving. Easy to install. the JRZ RS is available as a complete kit with mounting hardware and springs for all applications we support.  Following JRZ’s design philosophy. the JRZ RS has a large 22 mm diameter piston rod in strut applications and a 16 mm in aluminium damper applications. This means responsive chassis control at even the smallest suspension movements.  The large piston rod in combination with the high nitrogen gas pressure creates a lifting force giving great chassis control without using a high spring rate.  Our twin tube design uses a smaller diameter piston that gives a smooth feel during street driving. Working in conjunction with our blow off compression valving patterned from our racing dampers. the JRZ RS valving is the perfect marriage between daily driving and club racing.  To work with all ranges of spring and driver needs. the JRZ RS has an extra large adjustment range. With a few clicks you can turn your smooth street car into a crisp. rock solid track car in seconds.

Features

• 22mm piston rod
• Pre-set high gas pressure
• Piston developed for street and track
