PROGRESSIVE SUSPENSION 444 Series Shock - Black - Heavy-Duty - 12" 444-4058B

If you're pushing your bike to its limits, stock shocks simply won't cut it. The Progressive Suspension 444 Series delivers real-time damping adjustments through Frequency Sensing Technology, automatically calibrating to every bump so you get consistent performance whether you're cruising or attacking the track. Built for heavy-duty applications, these shocks maintain their composure when your bike is loaded hard and ridden harder.

The 444-4058B combines progressive-rate springs with high-pressure gas charging and deflective disc valving to eliminate harshness while maintaining control. Hand-adjustable pre-load means you can dial in your setup without special tools, and the 12" length gives you quicker steering response with a slightly higher front end—perfect for riders who want sharper cornering geometry.
