FORM, MEET FUNCTION!

A good pair of shocks are among the most essential parts of your motorcycle that ensure a quality riding experience. After all, a smooth ride is a safe ride.

The Progressive Suspension 444 Series Shocks offer the highest quality suspension available – featuring patented Frequency Sensing Technology (FST) and top-quality materials and innovation – crafted to ensure your ride is as smooth as possible.

After more than a decade of ruling the roads, Progressive Suspension unveiled another breakthrough design. Dubbed Frequency Sensing Technology (FST) for its unique ability to dynamically adjust damping as you ride. The result is superior performance no matter the road conditions. A top mount threaded preload adjuster allows for fine-tuning with a simple twist of the cap.

The 444 Series Shocks have the unique ability to dynamically adjust damping as you ride, so whether you’re hitting the small or big bumps in the road, the shock distributes oil through ports accordingly for an ultimately comfortable ride. A top mount threaded preload adjuster allows for fine-tuning with a simple twist of the cap.

444 Series shocks are available in 3 configurations: Standard Weight, Heavy-duty (250+ lbs.), and Super Heavy Duty (Touring Models only – 350+ lbs.). Every 444 shock is hand-built, tuned and dyno’d and includes a Limited Lifetime Warranty.

If you’re looking for an advanced dynamic suspension shock, look no further!
