Description
If you’re running your bike hard—especially at or near its maximum load capacity—stock shocks simply won’t cut it. The Progressive 444 Series delivers real-time damping adjustments through Frequency Sensing Technology, automatically responding to bump inputs instead of using fixed valving. You get consistent performance, improved handling, and the durability you need when every ride pushes the limits.
Built with a progressive-rate spring and high-pressure gas charging, these heavy-duty shocks maintain consistent performance across varying load conditions and riding intensities. The hand-adjustable spring preload means you can dial in your setup without special tools, while the deflective disc valving absorbs impacts smoothly. Note that the 13.5″ length may slightly alter your head angle and steering response compared to stock—confirm your wheel travel can accommodate the change before installing.
