What is Frequency Sensing Technology (FST)?

Frequency Sensing Technology (FST) is a patented system developed by Progressive. It allows the shock absorber's damping to automatically adjust in real time based on the frequency of impacts from the road and changes in the vehicle's weight. This means the shocks adapt to different conditions without requiring manual adjustments.

What is the benefit of the remote reservoirs?

The remote reservoirs on these shocks help to increase the oil capacity and surface area for cooling. This is particularly beneficial during strenuous off-road driving or when the suspension is working hard, as it helps to prevent shock fade and maintain consistent damping performance.

Do these shocks come with all the necessary hardware for installation?

This product includes the pair of rear shocks. For specific hardware requirements and installation procedures, it is recommended to refer to the manufacturer's installation instructions or consult with a qualified mechanic to ensure all necessary components are accounted for.

About this part

Product Details

The patented FST (Frequency Sensing Technology) piston assembly inside these Progressive 47 Series 2.0 rear shocks is a key piece of their design. It means the shocks can automatically adjust their damping curves in real time, based on the road conditions and any changes in vehicle weight. This technology is designed to give you a smoother ride whether you're on the highway or tackling rougher terrain, and it works without you needing to make any external adjustments.

These rear shocks are built for the 2020-2024 Jeep Gladiator models that have a 3.5 to 4.0-inch suspension lift, excluding the Mojave trim. The 2.0-inch diameter bodies and remote reservoirs help manage heat during demanding use, which is important for consistent performance. By adapting to different situations, this FST system aims to reduce the impact of road imperfections reaching the cabin, making your driving experience more comfortable.

This pair of rear shocks is a solid option if you're looking to improve your Gladiator's on- and off-road ride quality. They are designed to fit right onto your vehicle with the specified lift height, and the advanced damping technology takes the guesswork out of tuning your suspension for various conditions.
