The JRZ damper design comes from 60 years of experience in Research and Development of suspension and damper design for racing, rally, off road, HEAVY-DUTY and industrial applications. The approach of the JRZ design philosophy is completely different from other damper manufacturers: “Emphasis is on controlling the un-sprung mass” This is achieved by Large fluid displacement because of the use of large diameter piston rod Lifting force of shock-absorber by using high nitrogen pressure.
