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 adjust automatically in real time based on the input it receives from the road and the vehicle's movement, aiming to provide a smoother ride in various conditions.

Do these shocks require manual adjustment?

No, these STR 46 Series shocks are designed with FST technology that dynamically adjusts damping curves on its own. This means there's no need for external adjustments or manual tuning for different driving scenarios.

What is the lift height range for these rear shocks?

These rear shocks are specifically designed for Jeep Wrangler JK models that have a suspension lift between 3.5 inches and 5.0 inches.
