JRZ Coilovers Upgrades & Options
JRZ Suspension Engineering offers a range of performance upgrades to take your dampers to the next level. Whether you’re chasing lap times on track or dialing in your street setup, these factory-engineered options let you customize your JRZ dampers for your exact needs. All upgrades are available across both the RS and Motorsport product lines.
FA3030 Piston Upgrade
The FA3030 piston is JRZ’s advanced motorsport piston, designed to unlock a significantly larger range of damping curves. This upgrade gives race engineers the ability to create highly specific damping characteristics and fine-tuning options that go well beyond the standard piston configuration.
Key Benefits:
- Expanded range of achievable dyno curves for precise tuning
- Greater flexibility for race engineers to dial in specific damping profiles
- Enhanced fine-tuning capability across compression and rebound
- Optimized flow characteristics for smoother damping transitions
Available for: All JRZ RS Line and Motorsport Line dampers
25mm Piston Rod Upgrade
- Stiffer and stronger strut construction, especially under side loads
- Greater oil displacement for improved response at micro movements
- Enhanced damping sensitivity and precision
- Superior durability in high-load and demanding applications
Low Friction Shaft Coating
JRZ’s low friction shaft coating reduces friction on the main seal and dust seal, allowing the damper to respond with even greater precision to the smallest suspension movements. By lowering internal friction, stick-slip effects are minimized, resulting in smoother and more consistent damping performance.
Key Benefits:
- Enhanced damper precision at micro movements
- Reduced stick-slip on main seal and dust seal
- Smoother, more consistent damping response
- Extended seal life and reduced wear
Available for: All JRZ RS Line and Motorsport Line dampers
Quick Disconnect Hose Fittings
Quick disconnect fittings allow the external reservoir hose to be easily disconnected from the damper body. This eliminates the need for drilling or cutting during installation and makes removal significantly easier when working in tight spaces. The quick disconnect provides a clean, reliable connection that can be separated and reconnected without tools.
Key Benefits:
- Easy disconnect of external reservoir for installation and removal
- No drilling or cutting required during fitment
- Easier access through tight chassis holes and narrow spaces
- Clean, tool-free connection and disconnection
Available for: All JRZ RS PRO Lines and Motorsport Line dampers with external reservoirs
Upside Down Strut Upgrade
JRZ’s upside down (inverted) McPherson strut upgrade is the strongest and stiffest strut construction available. By inverting the strut design, the larger diameter tube is at the bottom where the bending forces are greatest, dramatically improving rigidity. This upgrade is ideal for vehicles that rely on McPherson strut suspension and are subjected to aggressive driving conditions.
Key Benefits:
- Strongest and stiffest McPherson strut construction available
- Dramatically improved rigidity under bending loads
- Reduced flex for more precise handling response
- Ideal for high-performance McPherson strut applications
Available for: JRZ McPherson strut applications across RS and Motorsport lines
