Progressive 444 Shocks For Harley Sportster 1986-2022
Transform Your Sportster Ride: Progressive 444 Shocks (1986-2022 XL)
If you own a Harley-Davidson Sportster from the Evo (1986) to the final Evolution models (2022), you know one of its biggest drawbacks: the harsh, short-travel stock suspension. Every bump, pothole, and expansion joint often results in a jarring hit right to your spine.
The solution is the industry-leading Progressive Suspension 444 Series Shocks. Engineered specifically for the Sportster’s unique geometry, these are the best replacement shocks for Sportster models, from the Iron 883 and Forty-Eight to the Custom and Roadster.
Stop Bottoming Out and Fix the Harsh Sportster Ride
The core reason the Progressive 444 is the ultimate Sportster suspension upgrade is its advanced damping system, which goes far beyond basic oil and springs:
1. Frequency Sensing Technology (FST)
This proprietary technology gives you the best of both worlds—smoothness and control—automatically.
Small Bumps: The FST valve opens wide to absorb quick, small road chatter, dramatically improving highway comfort and eliminating that constant, annoying harshness.
Big Hits: The valve instantly firms up when it senses rapid, high-impact movement, effectively preventing your Sportster from bottoming out on potholes or when hitting bumps while riding two-up.
2. Hand-Adjustable Preload for Any Load
Forget the days of using spanner wrenches or ignoring the settings altogether. The 444 Series features a simple, easy-to-reach threaded adjuster at the top of the shock. You can effortlessly dial in the perfect spring preload by hand for:
Solo Commuting: Set it soft for maximum compliance.
Two-Up Riding: Quickly crank it up to accommodate a passenger and gear, ensuring you maintain optimal ride height and safety.
We offer the Progressive 444 Heavy Duty Sportster option for riders or rider/passenger combinations who frequently exceed 225 lbs or ride aggressively. If you are consistently carrying a load, the HD spring rate will deliver superior control and ensure you stop bottoming out completely.
Upgrade your Harley Sportster’s suspension today and trade in spine pain for miles of comfortable cruising with the reliability and performance of Progressive Suspension.
