What does the FST technology do?

FST stands for Frequency Sensing Technology. It's a patented system that allows the shock absorber to dynamically adjust its damping curves in real time. This means it adapts to different road conditions and changes in vehicle weight to provide a smoother ride without requiring manual adjustments.

Are these shocks adjustable?

No, these STR 46 Series shocks are not externally adjustable. The patented FST technology automatically tunes the damping curves based on the driving conditions, eliminating the need for manual adjustments or complex tuning.

What is the benefit of a smooth body shock?

A smooth body shock, like these Progressive 46 Series shocks, typically offers better heat dissipation compared to a remote reservoir design. This helps maintain consistent damping performance, especially under demanding conditions or during extended use.

About this part

Product Details

The patented FST (Frequency Sensing Technology) piston assembly inside these Progressive 46 Series shocks is a smart piece of engineering. It means the shock dynamically adjusts its damping curves in real time, so you get a smoother ride whether you're on the highway or hitting some rougher terrain. This technology takes the guesswork out of tuning your suspension, letting you focus more on driving and less on fiddling with adjustments.

These are 2.0-inch smooth body shocks designed specifically for the 2018-2024 Jeep Wrangler (JL) and 2020-2024 Jeep Gladiator (JT) when lifted 3.5 to 4.0 inches. The smooth body design helps dissipate heat, which is important for consistent performance, especially during longer drives or when carrying extra weight. You're getting a well-built front shock pair that's engineered to adapt to changing road conditions and vehicle weight, providing a more comfortable experience for occupants.
