What is Frequency Sensing Technology (FST)?

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

Do these shocks come with everything needed for installation?

This product includes a pair of front shocks with remote reservoirs. It is recommended to consult the manufacturer's installation guide for a complete list of any additional hardware or tools that may be required for proper installation on your lifted Jeep Wrangler.

How do the remote reservoirs benefit my Jeep Wrangler?

The remote reservoirs are connected to the main shock body and contain additional shock fluid. This setup helps to keep the shock fluid cooler under heavy use, which prevents shock fade and ensures consistent damping performance, especially during demanding off-road driving or when the suspension is working hard.

About this part

Product Details

If you're looking to improve your 2007-2018 Jeep Wrangler JK's ride quality and handling, especially with a 3.5 to 5-inch suspension lift, these front shocks from Progressive are a solid option. These are the STR 47 Series 2.0 shocks, featuring remote reservoirs for better heat dissipation during hard use. They are designed to work with lifted Jeeps, providing a smoother ride across a variety of terrains.

What sets these shocks apart is Progressive's patented Frequency Sensing Technology (FST). This advanced system automatically adjusts the damping curves in real time based on road conditions and changes in vehicle weight. This means you get a more comfortable ride without the harshness often associated with lifted vehicles, and you don't have to manually adjust anything. The FST piston assembly takes the guesswork out of tuning, allowing you to spend more time driving and less time fiddling with suspension settings. The remote reservoirs help keep the shock fluid cooler, which is crucial for consistent performance, especially during off-road excursions or when carrying extra weight.

This pair of front shocks is designed for direct installation on your Jeep Wrangler JK with a 3.5 to 5-inch lift. They are well-built to handle the demands of off-road driving while also providing an improved on-road experience. You'll notice a difference in how the vehicle handles bumps and uneven surfaces, with less road noise reaching the cabin.
