What is Frequency Sensing Technology (FST)?

Frequency Sensing Technology is Progressive's patented system that allows the shock absorber to automatically adjust its damping based on road conditions and changes in vehicle weight. This means the shock adapts in real time for a smoother ride without requiring manual adjustments.

What is the purpose of the remote reservoir?

The remote reservoir is connected to the main shock body and holds extra shock fluid. This helps to dissipate heat more effectively, especially during demanding use like off-roading or aggressive driving, which keeps the shock performing consistently.

What suspension lift height are these shocks designed for?

These rear shocks are designed for Jeep Wranglers with a suspension lift ranging from 2.0 inches to 3.0 inches. Using them on vehicles outside this range may affect performance and proper operation.

It dynamically adjusts the damping curves in real time, meaning it can handle different situations without you needing to make any manual adjustments. This means it can help reduce road noise from reaching the cabin and provides a more comfortable experience whether you're on the highway or tackling rougher terrain. The remote reservoir helps manage heat during hard use, keeping the shocks performing consistently.
