About this part

Product Details

The patented FST (Frequency Sensing Technology) piston assembly inside these Progressive 46 Series 2.0 rear shocks is a smart piece of engineering. It means the shock automatically adjusts its damping based on road conditions and changes in vehicle weight, so you get a smoother ride whether you're on the highway or hitting some trails. This technology takes the guesswork out of tuning your suspension, letting you focus more on driving.

These shocks are built for the 2007-2017 Jeep Wrangler JK models that have a suspension lift between 1.5 and 3.0 inches. The smooth body design helps with heat dissipation, which is important for consistent performance during extended use. Because they're designed to adapt in real time, they help reduce road noise from reaching the cabin, making your Jeep a more comfortable place to be, even on rougher terrain.

This is a pair of rear shocks, and they're a well-built option for JK owners looking for improved ride quality without the hassle of manual adjustments. They are designed to fit right onto your Wrangler with a 1.5 to 3.0-inch lift.
