VAC Tech Tips:
This is a monotube race style design but smart for the street/track day enthusiast. Yes, it is a single way damper (more is not always better) but it shares the same technology as the RS Pro remote reservoir systems. How? There is a seperate gas charge area in actual piston body and a divider piston which divides the nitrogen charge from the oil charge.

JRZ is known for using large piston rods. This large piston rod configuration displaces a lot of oil, resulting in very quick valve action. This means you can enjoy a 'softer' ride but still have an incredibly well controlled chassis. Cheaper dampers with small piston rods require much more effort to move the shim stacks.

We have been selling JRZ solutions to race customers for quite some time so we are intimate with their superior engineering, design and performance. Since JRZ is on the cutting edge on technological development it made a lot of sense for them to create this new RS-1 system for street driven cars that will see track day events. True race technology in a practical kit. This is a unique system that can run with just springs or height adjustable perches. (PM for info on height adjustability)

JRZ Sales pitch:
JRZ Suspension Engineering is proud to introduce the JRZ RS1, a revolutionary development in multipurpose high performance damping. Applying our race winning technology, JRZ designed the JRZ RS1 to give ultimate comfort for public roads and precise chassis control when driving on track.

The JRZ RS1 is a high gas pressure, single adjustable monotube damper. The canister has been designed inside of the damper. JRZ inner canister technology gives the advantages of monotube canister dampers without the mounting concerns and complexity.

Easy to install, the JRZ RS1 is available as a complete kit with mounting hardware and springs for all applications we support. Built on the same production line and sharing components with our pro racing applications, the JRZ RS1 is of true professional heritage.

Following JRZ’s design philosophy, the JRZ RS1 has a large 22mm diameter piston rod in strut applications and a 16mm diameter piston rod in aluminium damper applications. The large piston rod magnifies the high pressure gas charge which means great chassis control without using a high spring rate or increasing harshness.

Utilizing a mono tube design with a high flow piston ensures the smoothest possible ride in normal conditions while the bleed adjustment gives the ability to tune for racing situations. Unlike many other single adjustable suspensions, damping balance is carefully maintained between compression and rebound. This damping balance is critical to maintaining tire contact with the road in addition to controlling the main mass of the vehicle.

To satisfy the diverse needs of each driver’s application, the JRZ RS1 has an extra large adjustment range. With a few clicks you can turn your smooth street car into a crisp, rock solid track car in seconds.

• 22 mm rod strut, 16 mm rod damper
• 12 clicks of compression
• 24 clicks of rebound
• Adjustable gas pressure, mono tube
• Piston designed for high performance

JRZ has designed the JRZ RS1 to give the end user the best possible damper to drive daily, while maintaining the racetrack performance that wins championships. The JRZ RS1 is shipped as a bolt-on kit and always comes with the personal support JRZ is known for.

Using the best materials, coatings and aerospace standard manufacturing processes as in our motorsport line; the JRZ RS1 is designed to perform flawlessly. Adjustment is easy to perform and comes with the knowledge base only JRZ provides to his customers.

• Easy to use and bolt-in
• Street ride, racing performance
• Extra long product life
• One adjustment for complete control of ride and handling
• Professional racing quality

Recommended applications
