CorteX 1994-2004 Mustang Xtreme-Grip™ JRI Double Adjustable Coil-Over System
Proven Performance and Durability
This coil-over system upgrade applies race-winning technology to your vehicle by providing precision chassis control, ride height and geometry alignment.
The JRI piston’s lower cross-section and reduced port length improve overall dynamic performance. These features coupled with JRI’s precise flow metering increase the hydraulic stiffness of the strut and improve its overall response.
- Struts Assembly with Single Adjustable JRi Internals (pair)
- Camber Plate (pair)
- Choice of Springs
- All mounting hardware to complete the installation
- JRi Double Adjustable dampers
- Springs and appropriate valving
- Coilover hardware
- Mounting brackets and hardware
Unique Piston Design
The JRI strut’s low friction seal design has less stick-slip than other leading strut manufacturers. Innovative components like the extension cage, and meticulous attention to sealing any unintended bleed paths, JRI struts have less hysteresis than competing manufacturer’s struts. The proprietary bearing carrier isolates side loads associated with misalignment that occur in normal strut operation. This is especially important with weight transfer. The result is a lower dynamic force and lower effective rate influencing your setup.
By design, more energy is dissipated through the fluid and NOT through the friction of the components.
- adjusts to high-speed extension
- adjusts to low-speed compression or extension through the shaft
The Professional Engineering Difference
Bulletproof steel housing and mounting brackets offer more tire clearance and reduced weight than bulkier aluminum components.
Why steel? Because aluminum deflects 3 times more than steel however it is also 1/3 the weight, when CorteX designs a component for stiffness we understand the aluminum needs to be 3 times thicker to have the equivalent stiffness of the steel parts.
Don’t be fooled… no weight will be saved without compromising durability by using aluminum. Steel also has superior fatigue properties than aluminum which means that it can be loaded closer to its limits over time (cycles) without fatigue failures. Aluminum, in contrast, must be kept further below its load limits to avoid fatigue failure. That is the exact reason that lightweight airplane components are replaced on a predetermined schedule since the engineers know how long the aluminum parts can safely be kept in service before a fatigue failure is likely to occur.
Installation is straightforward as coil-over hardware, springs, and all mounting brackets are included. With longevity and performance as priorities, all components use high-grade materials ideal for the application with durable finishes. Damper valving has been optimized and will take you to the next level of performance.
