JRZ Shock Dyno Services

The shock dyno is one of several tools we use for diagnosing problems and performance inconsistencies in your shocks. JRZ will maintain a complete history of your shock absorbers and provide a Log Sheet with every shock absorber to help us track, diagnose and improve your potential.

JRZ Shock Service
We recommend an examination after each racing season to maintain optimum performance and to provide preventative maintenance. JRZ's shock overhaul package includes a complete oil change and replacement of all o-rings and seals, followed by a thorough inspection on the shock dyno.

JRZ Shock Revalve Service
JRZ is available to discuss shock modifications. These consultations will enable you to more specifically match performance cures to certain tracks or applications.

JRZ Shock Testing Service
JRZ also offers the services of our suspension engineers trackside. They will advise, support, and service your shocks anywhere in the world. After each test session, you will receive a detailed report of the set-up, shock curves, and testing results.

JRZ Trackside Support

Trackside support will consist of on site consultation and specific suspension tuning. This is accomplished by a JRZ representative interpreting driver feedback along with the specific tracks characterisitics. Trackside support can benefit any team or individual. In many races where fractions of a second matter immensely this invaluable support can give you the winning edge.

DA (double-adjustable)

2way01

The double-adjustable shock allows external adjustment of both rebound and compression. In addition to the same precise and accurate rebound adjustment mechanism in the single-adjustable, the double-adjustable shock has a remote reservoir with the compressi

on adjuster and gas volume. This reservoir is connected to the shock with a Teflon-lined high-pressure hose and uses a 22mm piston rod. The double-adjustable allows you to refine the handling of your car by adjusting both the rebound on the shock rod and the compression blow-off valve in the remote reservoir.

FEATURES:

  • Precise rebound control mechanism
  • Gas pressure adjustment becomes an effective tuning tool
  • Unique compression adjustment mechanism

TA (triple-adjustable)

The triple-adjustable is identical to the double adjustable with the exception of an additional compression adjustment added. This allows for more fine-tuning of the suspension. Teamed with the race proven capabilities of the JRZ single- and double-adjustable shocks, the triple-adjustable shock 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 shock 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 (shock 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 shock rod movements. The JRZ triple adjustable shock is the way to go to fine tune your racecar.

FEATURES:

  • Very sensitive and responsive compression adjustment mechanism
  • Large piston rod provides maximum oil flow on small movements
  • Precise rebound control mechanism
  • Light weight and high strength
  • Better heat dissipation
  • Ride height adjustable
  • Outstanding repeatability

JRZ RS

The RS street dampers have been developed from many years of professional racing experience. The RS damper allows for external adjustment of both the rebound and compression functions of the damper. In addition to the same precise and accurate rebound adjustment as in the single adjustable race damper, the RS are double adjustable. The compression adjustment technology is the same as that of the race version. The RS does not utilize a separate canister. The RS has both the rebound and compression adjustments on the damper itself.

JRZ RS Pro

The RS Pro takes the RS one step further with the addition of an external reservior canister. The RS Pro utilizes the external reservior to house the precise compression adjustment mechanism.
