Progressive Harley 444 Series Shocks 13.0in Super Heavy Duty - Black

Progressive Suspension is well-known for making high-performance suspension components for motorcycles, and their 444 Series Shocks are a prime example of that expertise. These 13-inch Super Heavy Duty shocks are built for touring models that carry a heavier load, typically 350 lbs and up, offering a significant upgrade over stock suspension. They feature Progressive's patented Frequency Sensing Technology (FST), which automatically adjusts the damping based on the frequency of bumps encountered on the road. This means the shocks can soak up both small road imperfections and larger impacts more effectively, leading to a more comfortable and controlled ride, especially on longer journeys.

The Super Heavy Duty configuration uses a progressive rate spring designed to handle increased weight without bottoming out. You can also fine-tune the spring preload by hand using the top-mounted threaded adjuster, allowing you to dial in the suspension for your specific riding style and load. The shocks also utilize a reflective disc valving system for consistent damping performance. These shocks are made in the USA and come with a limited lifetime warranty, reflecting Progressive's confidence in their well-built products.

These shocks fit a wide range of Harley-Davidson touring models, including popular bikes like the Road King, Electra Glide Standard, and Ultra Limited. If you're looking to improve the ride quality and handling of your heavier touring motorcycle, especially when carrying a passenger or cargo, these 444 Series shocks are a solid option.
