What is Frequency Sensing Technology (FST)?

Frequency Sensing Technology (FST) is a patented system developed by Progressive that allows the shock absorbers to automatically adjust their damping characteristics in real time. It senses changes in the road and vehicle weight to provide a smoother and more controlled ride without requiring manual adjustments.

Do these shocks come with everything needed for installation?

This product includes a pair of front shocks with remote reservoirs. It is recommended to consult the manufacturer's installation guide for a complete list of any additional hardware or tools that may be required for proper installation on your Jeep Wrangler.

How do the remote reservoirs benefit my Jeep Wrangler?

The remote reservoirs help to separate the shock fluid from the piston rod, which allows for better heat dissipation. This is especially important during demanding driving conditions, as it helps prevent shock fade and maintains consistent damping performance for a more reliable ride.

About this part

Product Details

If you're looking to improve your 2007-2017 Jeep Wrangler JK's ride quality and handling, especially when lifting it between 1.5 and 3.0 inches, these front shocks from Progressive are a solid option. They feature Progressive's patented Frequency Sensing Technology (FST) in the piston assembly, which means the shocks automatically adjust their damping based on the terrain and vehicle weight. This technology works to smooth out bumps and reduce the impact of road imperfections, so you can spend more time enjoying your drive and less time fiddling with adjustments.

The STR 47 Series shocks are built with 2.0-inch diameter bodies and come with remote reservoirs. These reservoirs help keep the shock fluid cooler under demanding conditions, which is crucial for maintaining consistent damping performance. The FST system dynamically changes the damping curves in real time, adapting to different road conditions and changes in vehicle weight without requiring any manual input from you. This means you get a more comfortable ride whether you're cruising on the highway or tackling rougher trails.

This pair of front shocks is designed as a direct fit for lifted Jeep Wranglers from 2007 to 2017. The remote reservoir design is a notable feature that helps manage heat buildup, ensuring the shocks perform reliably even when pushed. You'll notice an improved feel over various surfaces, as the FST technology works to isolate the cabin from harsh impacts.
