Progressive Harley 444 Series Shocks 13.5in - Chrome

If you're looking to significantly improve the ride quality on your Harley-Davidson, these Progressive 444 Series Shocks are a solid option. Designed to fit a wide range of Harley models, including popular bikes like the Road King, Electra Glide, and Street Glide, these 13.5-inch chrome shocks offer a noticeable upgrade over stock suspension. They work by dynamically adjusting damping based on the frequency of bumps, meaning they can soak up both small road imperfections and larger impacts for a smoother, more comfortable journey.

What makes these shocks stand out is their patented Frequency Sensing Technology (FST). This advanced system uses a unique internal design with a deflective disc valving system that automatically distributes oil through specific ports as you ride. This means the damping force changes instantly to match the road conditions, providing a more controlled and comfortable feel whether you're cruising on the highway or navigating city streets. 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 or load. They come with a progressive rate spring, which offers a softer initial feel that stiffens as it compresses, further enhancing comfort and control.

These shocks are available in different configurations to suit your needs, including standard weight and heavy-duty options for riders over 250 lbs. This particular model is the 13.5-inch chrome version, offering a classic look that complements many Harley-Davidson models. They are well-built in the USA and come with a limited lifetime warranty, giving you peace of mind with your investment.
