The JRZ damper design comes from 60 years of experience in Research and Development of suspension and damper design for racing, rally, off road, armoured 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
  • Compression damping with unique adjustable valving system in canister
  • Large piston, with a large diameter non preloaded deflective disc valves
  • High flow return valve for quick refilling of working cylinder
  • Gas volume is selected in a way that the fluctuating gas volume and the temperature have little effect in the increase of pressure

Control of sprung mass

This is achieved by:

  • Large piston diameter for good rebound control because of large fluid displacement
  • Unique orifice rebound adjustment system


  • Improved handeling
  • Reduced tyre wear
  • More traction
  • Better comfort level
  • Better stability of vehicle body
  • Increased lifetime of damper
