What is Frequency Sensing Technology (FST)?

Frequency Sensing Technology (FST) is a patented system that allows the shock absorber's damping to adjust automatically 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?

These shocks are sold as a pair for the front of your Jeep Wrangler. While they are designed for a direct fit, it's always recommended to refer to the manufacturer's installation instructions for a complete list of any additional hardware or tools that may be required.

How do these shocks handle off-road driving?

The FST technology allows these shocks to dynamically adjust damping based on terrain. This helps them adapt to changing off-road conditions, providing a more controlled and comfortable ride while you're exploring trails.

About this part

Product Details

The patented FST (Frequency Sensing Technology) piston assembly inside these Progressive 46 Series 2.0 smooth body front shocks is a notable design choice. It means the damping automatically adjusts in real time based on road conditions and changes in vehicle weight, so you get a smoother ride without needing to manually tune anything. This technology is at the heart of what makes these shocks work well for your 2007-2018 Jeep Wrangler JK.

These shocks are built for Jeeps lifted between 1.5 and 3.0 inches, making them a solid option if you've modified your suspension for a bit more ground clearance. The smooth body design helps with heat dissipation, which is important for consistent performance, especially during longer drives or when the suspension is working hard. You'll notice less road noise reaching the cabin, and the ride changes dynamically to handle different surfaces, giving you more confidence on and off the pavement.

When you're looking to improve your JK's on-road comfort and off-road capability, these shocks offer a well-built solution. They are designed to fit right onto your Wrangler, simplifying the installation process. You'll spend less time fiddling with adjustments and more time enjoying the improved ride quality.
