JRZ Suspension Engineering is proud to offer our newest triple adjustable racing damper. the JRZ 12 31. Building upon the years of success of our original triple adjustable damper. the JRZ 12 31 takes our damping philosophy to the next level. Every adjustment has an increased damping force range with finer adjustments engineered to enable the chassis tuner to make significant predictable changes every time. Compression adjustments are separated into the high speed and low speed piston velocity ranges affecting the bleed and blow off points of the damping curve. All oil flow paths in the JRZ 12 31 have been redesigned to maximize efficiency and give crisp feel to the driver. Rebound valving has been completely redesigned to eliminate influence over compression forces and smooth pressure development. At the heart of the new JRZ 12 31 package is our latest motorsport piston. designed to give increased control over base characteristics. reduce hysteresis. and operate smoother. To ensure that the valving designed into the JRZ 12 31 are the determining forces. JRZ has included new low friction coatings. seals and bearings with this package. Custom applications are available. An easy to use system. the JRZ 12 31 enables the chassis tuner to achieve the desired mass control and handling with precision. Digressive high speed compression blow off adjustment allows for a stiff compression valving while maintaining smooth response and without losing traction. The low speed adjustment is a powerful tool that enables the chassis tuner to maximize grip and optimize vehicle balance. The result is a damper that provides ultimate chassis and ride height control with maximum mechanical traction. The JRZ standard large 22 mm piston rod works in concert with the high speed valving to maximize blow off valve response. achieving solid chassis control without using a high spring rate.

JRZ 12 31 dampers are shipped with 360 degree swivel hoses and are available with zero-inclusion quick disconnects for mounting canisters within the chassis for ease of adjustment accessibility. Our newest motorsport piston has been developed to deliver a smooth and responsive damping characteristic.  To customize track to track setups and tailor the chassis to the driver; the JRZ 12 31 has an adjustment range able to provide damping to spring configurations ranging from 1.5-6Hz on vehicles with moderate to large aerodynamic loads. Even with a large range. each adjustment is designed to be small. even steps giving precision and confidence when making changes. The JRZ 12 31 is here to take you to the next level. Dedicated racing cars with experienced drivers deserve the professional technology JRZ delivers. With valving designed and innovated by JRZ Suspension Engineering. the JRZ 12 31 is shipped as a custom configuration always tailored to the customer’s needs. and always comes with our world renowned personal service.

JRZ Suspension is proud to offer our Triple Adjustable racing damper. Advancing the design of our Double Adjustable further. the JRZ Triple Adjustable utilizes the same piston design while adding function to the Triple Adjustable canister. Like the Double Adjustable. the Triple Adjustable has a wide adjustment range with precise. even adjustments engineered to enable the chassis tuner to make significant. predictable changes every time.

Compression adjustments are separated into the high speed and low speed piston velocity ranges. This level of adjustment creates an environment for precise tuning. The mono tube Triple Adjustable Damper offers a wide adjustment range allowing the user to tailor the damper to driver. track and vehicle. The JRZ Triple Adjustable Damper is available as a complete kit with springs and mounting hardware. Custom applications are available.

For: Subaru WRX Sti YR: 2004-2011 Cyl: 4 App: 2.5L Turbo 6-SHPeed
The versatile FX500 System uses either the Power Plus I or Power Plus II Pressure Plate along with a solid center 4,6 or 8 wing (paddle) Ceramic Button disc. The FX500 disc is designed for outstanding holding capacity and rapid heat dissipation. The FX500 ceramic paddle design creates a quick and rapid engagement as well as clutch chatter that is not recommended for the street. Learn More

Clutch Masters 725/850 Series: Ultra High Performance Twin Disc Street or Race Systems; 300-600% increase in holding capacity Clutch Masters Twin Disc systems are pure racing technology that also works well in high performance street applications. They are designed to hold tremendous horsepower and torque ratings, while retaining a very smooth operation. By slightly increasing the clamping force of the pressure plate and adding to the square inches of usable disc area, CM Twin Discs significantly increase clamping values with only a 25-50% increase in pedal pressure depending on the application. The cover assembly is machined from billet aluminum with 25% more tensile strength than the competition’s cast unit. The flywheel is machined from billet 6061-T6 aluminum to meet SFI spec 1.2 for competition in NHRA, NDRA, IDRC, IHRA, SCCA and NASA. Each aluminum flywheel includes a replaceable heat shield. Steel flywheels are also available on select applications. *725 SERIES – (7.25” Twin Disc) The 725 series is a smaller diameter assembly, which creates less rotating mass and offering quicker, and smoother shifting with much better throttle response. *850 SERIES – (8.50” Twin Disc) The 850 series is a larger diameter assembly, which is designed for high horsepower applications that require smooth engagement, quiet operation and high clamp load. All systems include: * Cover Assembly with attached Diaphragm * Pressure Plate Ring * Two Discs * One Mid Plate * Billet Aluminum Flywheel* * Release Bearing * Pilot Bearing (when applicable) * Pressure Plate Bolts Learn More

The FX400 System uses the Power Plus I Pressure Plate with a custom, extremely durable, Sprung Ceramic disc. This is the ultimate extreme duty street and/or road/drag racing system. It is available in a 4,6 or 8 wing (paddle) configuration, with the 4-wing being the more aggressive setup and 8-wing being the less aggressive (please specify which type you prefer). The sprung hub design allows for moderate dampening in high-torque applications, rendering it much more street friendly than solid or rigid designs. This disc is designed for outstanding holding capacity, and rapid heat dissipation. The FX400 ceramic paddle design creates a quick and rapid engagement as well as clutch chatter that may not be ideal for street driven vehicles.  Learn More
