Xtreme-Grip Front Coil-Over Struts, 2005-2014 Mustang S197, Double Adjustable JRi Dampers

 

These struts include all the geometry advantages of our other competition struts such as the ability to fit 10.5-11 in wide from wheels and 315mm tires.  Now they are available with the advantages of JRi damper technology.

Bullet proof steel housing and mounting brackets off more tire clearance and reduced weight than bulkier aluminum components.  Since struts see significant bending loads (unlike shocks which are mostly limited to tension and compression loads) stiffness of the housing is essential in order to minimize camber loss and prevent bending and component damage in the event accidental abuse from contact or an off-track excursion.  Engineers know that aluminum deflects 3 times more than steel however it is also 1/3 the weight.  What this means is that if you are designing a component for stiffness the aluminum needs to be 3 times thicker to have the equivalent stiffness of the steel parts.  With that knowledge it is easy to deduct that no weight will be saved by using aluminum in the design.  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.

The JRI piston’s lower cross-section and reduced port length improves overall dynamic performance. These features coupled with JRI’s precise flow metering increase the hydraulic stiffness of the strut and improve its overall response. With its unique piston design, 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. By design, more energy is dissipated through the fluid and NOT through the friction of the components. The JRI strut’s low friction seal design has less stick-slip than other leading strut manufacturers. The result is lower dynamic force and lower effective rate influencing your setup. This added adjustment feature allows the struts to not only adjust high speed extension, but also to adjust low speed compression or extension through the shaft.

    Excellent fit and quality. Ride is only a little stiffer over stock (GT500) and actually less noise than the stock struts when going over speed bumps. Was able to adjust the ride height without a spanner wrench. Ended up with about 3/32″ clearance between the tire and strut. Running 305/30ZR-20 Michelin Pilot Sport Cup 2 K1 Ferrari XL tire on 20×10.5 with 52mm offset rims. Would recommend this product.
