What is Frequency Sensing Technology (FST)?

Frequency Sensing Technology (FST) is a patented system that allows the shock absorber's damping to adjust automatically based on the frequency of impacts. This means it can react to different road surfaces and changes in vehicle load in real-time, providing a smoother ride without requiring manual adjustments.

Do these shocks come with everything needed for installation?

These shocks are sold as a pair for the rear of your Jeep Wrangler. While they are designed as a direct replacement for lifted applications, it's always recommended to consult the manufacturer's installation instructions to confirm if any additional hardware or specific tools are required for your setup.

What is the benefit of the remote reservoirs?

The remote reservoirs on these shocks help to increase the shock's fluid capacity and surface area. This aids in dissipating heat more effectively, which is crucial for maintaining consistent damping performance during extended use or under heavy loads, preventing shock fade.

About this part

Product Details

The patented FST (Frequency Sensing Technology) piston assembly inside these Progressive 47 Series 2.0 rear shocks is a notable design choice. It means the shock dynamically adjusts its damping curves in real time, adapting to changing road conditions and vehicle weight without you needing to make any manual adjustments. This technology is at the heart of what makes these shocks work so well for your 2007-2018 Jeep Wrangler JK, helping to smooth out the ride whether you're on the highway or tackling rougher terrain.

These rear shocks are built for JK Wranglers with a 1.5 to 3.0-inch suspension lift. The 2.0-inch body and remote reservoirs help manage heat buildup during extended use, which is crucial for maintaining consistent performance, especially when you're pushing your Jeep. The FST system works to eliminate harsh impacts and road noise from reaching the occupants, making for a more comfortable experience on longer trips or off-road adventures. You get a well-built pair of rear shocks designed to handle a variety of driving scenarios right out of the box.

When installing these rear shocks, remember they are designed to work with a 1.5 to 3.0-inch lift kit. Ensure you have the correct hardware and follow the manufacturer's installation guidelines to get the most out of their advanced damping technology. This pair is a solid option for improving your JK's on-road comfort and off-road capability.
