Not your average street-car brand.

 

Race Series:

The JRZ Racing dampers are used by race teams all over the world competing in race classes ranging from Asian GT to Rolex series, Formula 3 to IRL. The JRZ Racing product range contains single, double, triple and quadruple adjustable dampers.

 

     
KW Suspension Variant 1  

JRZ Race Single Adjustable

- Precise rebound control system
- Minimum weight and size

The JRZ single adjustable dampers have a rebound adjuster, located at the top of the pistonrod. It adjusts the rebound and compression, with this one adjuster but it mainly adjust the rebound.

The JRZ single adjustable dampers runs no external reservoir.The oil and gaspressure are separated by a divider piston, which makes the damper mountable either upright or upside-down.

Used by all types of cars like Formula Superclio.

- Formula Racing
- Touring Car
- Street performance
- Dirt Track
- Cross

     
KW Suspension Variant 1  

JRZ Race Double Adjustable

- Gas pressure adjustment becomes an effective tuning tool
- Unique compression adjustment mechanism
- Large 22m piston rod
- Available in piggyback design

The double adjustable damper is adjustable in both rebound and compression. In addition to the same precise and accurate rebound adjustment mechanism as in the single adjustable, the double adjustable damper has a remote reservoir with the compression adjuster and gas volume.

This reservoir is connected to the damper with a Teflon-lined high-pressure hose. With the 22 mm diameter pistonrod, a large volume of oil is displaced by even the smallest movements of the suspension This translates into a very precise and sensitive compression adjustment, necessary for a race car.

- Formula Racing
- Rally (upsclasse-down available)
- Touring Car Racing
- Street performance
- Dirt Track
- Cross

     
KW Suspension Variant 1  

JRZ Race Tripple Adjustable

- Very sensitive and responsive compression adjustment mechanism.

The tripple-adjustable damper has a separate adjustment device to control the low speed compression damping forces without affecting the mid- and high-speed range. Because the large 22mm piston rod provides sufficient oil flow on very small and low-speed damper movements, the low-speed adjuster mechanism is very sensitive and responsive.

The low-speed adjuster uses a bore design in which the area can be varied. The adjuster is located on top of the remote reservoir and has eight adjustment positions. Changes made to low-speed damping forces (damper rod velocity of less than 1.5 – 2 inches per sec.) have a major effect on handling because corner entry, corner exit, braking, and power down are all about low speed piston rod movements.

- Street performance
- Dirt Track
- Cross
- Rally (upsclasse-down available)
- Touring Car Racing

     
KW Suspension Variant 1  

JRZ Race 4 - Way Adjustable

- High strength and performance.
- Precise bump and rebound control mechanism.
- Large piston rod provclasses maximum oil flow on small movements.
- Very sensitive and responsive high speed bump and rebound adjustment mechanism.
- Outstanding repeatability
- Rclasse height adjustable

The high-end  4-way adjustable damper is the top in the JRZ product line. The main philosophy behind the 4-way is the fact that low speed piston movement influences the roll and pitch characteristics of the cars handling.

The high speed piston speeds occur when driving over bumps and curbs. The 4-way adjustable damper makes it possible to tune the cars behavior independently in all situations.

- Touring Car Racing
- Street performance
- Rally (upsclasse-down soon available!)
- Dirt Track
- Cross
