What is Frequency Sensing Technology (FST)?

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

Do these shocks come with everything needed for installation?

This product includes the pair of front shocks with remote reservoirs. It is recommended to consult the manufacturer's installation instructions for any additional hardware or components that may be required for your specific lift kit setup.

How do the remote reservoirs benefit my Jeep?

The remote reservoirs help to keep the shock fluid cooler, especially during extended periods of hard driving or off-roading. This improved cooling helps maintain consistent damping performance and can extend the life of the shock absorber.

About this part

Product Details

Progressive is known in the powersports world for bringing new ideas to suspension. These STR 47 Series 2.0 front shocks for your 2018-2024 Jeep Wrangler (JL) or 2020-2024 Jeep Gladiator (JT) are a prime example, offering a significant upgrade over stock, especially if you're running a 3.5 to 4-inch lift. They feature Progressive's patented Frequency Sensing Technology (FST) right in the heart of the piston assembly.

What FST does is pretty neat: it automatically adjusts the damping based on how the vehicle is moving and changes in weight, like when you hit a bump or corner. This means you get a smoother ride across a variety of situations without needing to manually adjust anything. The technology dynamically tunes the damping curves in real time, so it can handle different road conditions and vehicle loads on the fly. This helps reduce road noise from reaching the cabin, making your drive more comfortable.

This pair of front shocks comes with remote reservoirs, which help keep the fluid cooler during heavy use, improving performance and consistency. They are designed to fit Jeeps with a 3.5 to 4-inch suspension lift, excluding the Mojave trim on the Gladiator. You'll get a well-built set of shocks that are ready to improve your on and off-road experience.
