The Ultimate Performance Challenger Charger coilover shocks are the ultimate double adjustable coilover suspension package for both the Dodge Charger and Dodge Challenger platforms. Not only can you get the stance you have always wanted, but we have complemented that with superior handling. Whether you are trying to apply all of that power off the line at the drag strip or drive faster through the corners on a winding road or the track, this package will give you what you need and more. UP custom valves JRi Shocks, specifically tuning them to compliment the horsepower for your Challenger or Charger. JRi Shocks are race proven dampers, utilizing the same racing technology for your performance car. The Ultimate Performance Challenger Charger coilover shocks provide superior handling and performance to your ride. Keeping the racing and performance aspects close to us, we have also used ETG, Earnhardt Technology Group, to manufacture the mounting hardware. The quality and craftsmanship of the components they produced are works of art, as they were when they were making the components for Dale Earnhardt himself.
The front and rear shocks are direct bolt in pieces utilizing Hyperco springs. The Hyperco springs eliminate spring sagging and the need to re-adjust ride height and corner weights. The use of thrust washers will maximize grip by taking the friction out of the springs as they compress. The JRi Shocks provide the largest range of adjustment on the market. This adjustment range is ideal for tuning your shocks to the track and any track condition.
On the front, we designed our own upper and lower mounts. The upper mounting plate uses a FK teflon lined bearing to reduce friction and eliminate bind throughout suspension travel. The JRi shock body threads into the lower clevis housing allowing for ride height adjustments without having to adjust the coil springs. For easy shock adjustments, both adjusters are located at the top of the shocks inside the engine compartment.
The rear shocks have been converted to a true eyelet to eyelet coilovers, no longer running the stock divorced shock and spring package. This keeps the shock and the spring running with the same motion ratio. The stock upper mount has been replaced with an aluminum mounting plate and clevis. The clevis allows us to use a high misalignment Teflon lined bearing for maximum articulation while reducing friction eliminating bind throughout the suspension. We use a raised spring perch for optimal half shaft clearance.
We have custom packages made specifically for drag racing and road racing.
