What is Frequency Sensing Technology (FST)?

Frequency Sensing Technology (FST) is a patented system by Progressive that allows the shock absorber's damping to adjust automatically in real time. It senses changes in road conditions and vehicle weight to provide a smoother ride without manual adjustments.

Do these shocks come with everything needed for installation?

This product includes a pair of rear shocks with remote reservoirs. It is recommended to consult the manufacturer's installation instructions to confirm if any additional hardware or components are required for your specific vehicle and lift setup.

How do the remote reservoirs benefit the shocks?

The remote reservoirs are connected to the main shock body and help to increase the shock's oil capacity and surface area. This aids in dissipating heat generated during operation, which helps maintain consistent damping performance, especially under demanding driving conditions.

About this part

Product Details

This product includes a pair of Progressive STR 47 Series 2.0 Remote Reservoir rear shocks designed for the 2018-2024 Jeep Wrangler (JL) with a 3.5 to 4.0-inch suspension lift. These shocks are built to automatically adjust their damping based on road conditions and vehicle weight, offering a smoother ride without requiring manual tuning.

At the heart of these shocks is Progressive's patented Frequency Sensing Technology (FST) piston assembly. This advanced design dynamically adjusts damping curves in real time, meaning the shock can adapt to various terrains and driving scenarios. The FST system works to absorb impacts and reduce the transfer of road noise into the cabin, so you can spend more time enjoying your drive and less time fiddling with suspension settings. The remote reservoirs help dissipate heat, allowing the shocks to perform consistently under demanding conditions.

These rear shocks are a solid option for Wrangler owners looking for an improved ride quality that adapts to changing conditions. Because they are designed for a specific lift height range, they are intended to fit right without extensive modification when installed on a vehicle within the specified lift range. Always refer to the manufacturer's installation instructions for detailed guidance.
