What does FST (Frequency Sensing Technology) do?

FST is Progressive's patented technology that allows the shock absorber to automatically adjust its damping characteristics in real-time. It senses the frequency of impacts from the road surface and changes the damping curve to provide a smoother ride and better control.

Do these shocks require manual adjustments?

No, the FST technology in these shocks eliminates the need for external adjustments or manual tuning. The piston assembly dynamically adapts to changing conditions, so you can spend more time driving and less time adjusting your suspension.

What is included with this pair of rear shocks?

This product includes a pair of rear STR 47 Series 2.0 remote reservoir shocks designed for your Jeep Wrangler JK. Installation hardware may vary; refer to the manufacturer's instructions for a complete list of included components.

About this part

Product Details

Progressive is known in the powersports world for bringing new ideas to suspension. This STR 47 Series 2.0 rear shock pair for your 2007-2018 Jeep Wrangler JK is a great example, featuring their patented FST design. This technology means the shock's damping automatically adjusts to changing road conditions and vehicle weight in real time, so you get a smoother ride whether you're on the highway or tackling rougher terrain. You won't need to worry about making manual adjustments or learning complex tuning procedures; the FST piston assembly handles it all.

These rear shocks are built for JK Wranglers with a 3.5 to 5.0-inch suspension lift. The 2.0-inch body and remote reservoirs help manage heat during hard use, keeping the damping consistent. The FST system works by sensing the frequency of impacts, dynamically changing the damping curve to absorb bumps effectively and reduce the transfer of road noise into the cabin. This means a more comfortable experience for you and your passengers, no matter what the road throws at you.

This pair of rear shocks is designed to fit right onto your Jeep Wrangler JK, making installation straightforward for those comfortable with suspension work. You'll notice an improved ride quality and better control over various surfaces thanks to the advanced damping technology.
