JRZ RS Line vs Motorsport Series – What’s the Difference?
JRZ RS Line – Daily Driven & Track Ready
The RS Series is ideal for performance enthusiasts who want the benefits of adjustable damping and comfort in a street-legal, track-capable package. These systems are perfect for daily drivers, autocross events, and weekend track days.

- RS Pro: Double adjustable with remote reservoirs for increased oil volume and cooling, improving consistency in extended track sessions.
JRZ Motorsport Line – Built for Competition
For serious racers and advanced drivers, the JRZ Motorsport Series delivers unmatched damping precision and thermal stability. These systems are designed for time attack, road racing, and professional-level motorsport use.
- Double or Triple Adjustable: Independent control over rebound, low-speed compression, and high-speed compression for race-specific tuning.
- Remote Reservoirs: Increased oil and nitrogen capacity improves thermal control and shock response.
- Custom Valving: Each damper is tailored to your vehicle’s weight, spring rate, and driving style.
Single vs Double Adjustable JRZ Dampers
Single Adjustable Dampers control rebound only, making them easier to set up for drivers who prioritize simplicity and street-friendly tuning. These are a great choice for autocross, canyon carving, and spirited weekend driving.
Double Adjustable Dampers allow independent tuning of rebound and compression. This level of control is ideal for track day drivers and racers who need to balance body control, traction, and ride quality under varying track conditions or tire setups.
