JRZ Suspension Engineering is proud to offer the 12 Series; Triple Adjustable motorsport damper. The JRZ 12 series is an expansion of our damping philosophy, which is to control the unsprung mass. Added from the 11 series is the low speed compression adjustment, allowing pitch, roll, and balance to be tuned.
MOTORSPORT TRIPLE ADJUSTABLE DAMPER:
Compression and rebound independently adjustable. Rebound adjusted by orifices on the piston rod with check valve so there is no cross talk between the rebound adjustments and compression forces. Compression adjusted by blow off valve in the canister.
Control of the unsprung mass is achieved with our blow off valve. Steering balance and weight transfer rates are tuned with the low speed adjustment. The high speed compression adjustment sets the blow off velocity of the damper, allowing for harshness to be separated from control. Blow off damping settles the car on bumps, curbs, and maximizes grip. Low speed sets the speed at which the blow off valve opens allowing for fine tuning of balance and adjusting for surface conditions.
Sprung mass is controlled with rebound damping, delivered smoothly by the 8060 motorsport piston. The 12 series rebound system and 8060 piston provides a linear damping characteristic with smooth pressure development independent of compression forces. This allows the damper to transition between rebound and compression efficiently, maximizing grip and reducing tire wear.
CONTROL OF UNSPRUNG MASS:
Control is achieved by using compression damping controlling the movement of the unsprung mass. By doing this the car will take kerb stones or road bumps extremely well and the car will not be unsettled with great control for the driver.
MINIMIZED TIRE WEAR:
Using compression damping to control the unsprung mass will result in less tyre wear and better tyre temps. The unsprung mass will move according the tyre’s natural frequency. Using the compression damping the contact patch of the tyre to the road will be maximized.
LARGE ADJUSTMENT RANGE:
Damping is available over a large adjustment range with fine tuning increments. Set up is easy to find and spring rates can be changed without having to revalve the damper
ADJUSTABLE GAS PRESSURE:
The combination of the 22 mm shaft and the use of nitrogen pressure results in a lifting force created by the damper. This lifting force is available through the whole stroke of the damper and works together with the spring, The lifting force is not a springrate, but gives the car platform..

History of JRZ Suspension
JRZ Suspension Engineering was founded in 1994 by Jan Zuijdijk. His mission was to bring a new and revolutionary damper design to the world of motor racing and high-performance sports cars. This new design would aim to eliminate the flaws of old-school hydraulic damper design and incorporate new insights into the complexity of vehicle dynamics and the role dampers play themselves.
J. Zuijdijk worked for Koni on its R&D team, leading him to envision exactly what needed to be modified when it came to the stagnant approach to damping and handling race car suspension. He also had conceived a strong sense of how the prominent role of the hydraulic damper needed to change.
JRZ Suspension Engineering is based in Uden, Netherlands, and has an office in the United States. JRZ produces racing and custom dampers for any application ranging from motorsports to armored vehicles. Each product is built and tested individually in the Netherlands to ensure only the highest quality possible.
Why Choose JRZ Suspension?
The unique JRZ damper design is the result of 60 years of experience in Research and Development of suspension and damper design for racing, rally, off-road, heavy-duty, and industrial applications. JRZ’s approach is completely different than that of other damper manufacturers. JRZ Suspension Engineering specializes in complete suspensions at all levels from bolt-in systems for daily drivers to customized motorsport solutions.
