What is Frequency Sensing Technology (FST)?

Frequency Sensing Technology (FST) is a patented system by Progressive 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 manual adjustments.

Do these shocks come with mounting hardware?

This product listing is for the front shock absorbers only. It is recommended to refer to the manufacturer's installation instructions or contact Progressive to confirm if any specific mounting hardware is included or if you need to reuse your original parts.

What is the benefit of a smooth body shock?

A smooth body shock, like these STR 46 Series shocks, typically offers a larger volume of oil compared to a traditional twin-tube shock. This can help with heat dissipation during heavy use, leading to more consistent damping performance.
