Progressive Harley 444 Series Shocks 13.5in - Black

When you grab this Progressive 444 Series shock set, you're getting a pair of 13.5-inch black shocks designed to fit a wide range of Harley-Davidson models, including popular bikes like the Road King, Street Glide, and Electra Glide. These aren't just replacements; they're an upgrade aimed at smoothing out your ride, whether you're cruising down the highway or navigating city streets. The key here is Progressive's patented Frequency Sensing Technology (FST). This advanced system automatically adjusts the damping based on the frequency of bumps it encounters, meaning it can soak up small road imperfections and larger impacts more effectively, leading to a more comfortable experience for you and your passenger.

Beyond the FST, these shocks offer a progressive rate spring, which means the spring gets stiffer as it compresses. This design helps provide a plush feel on initial impact while still offering solid support during harder compression, like when cornering or carrying a passenger. You also get a top-mounted threaded preload adjuster that lets you fine-tune the suspension's stiffness by hand – no special tools required, making it easy to dial in the ride for different loads or preferences. The shocks also feature a deflective disc valving system for consistent damping performance.

This set comes with standard or heavy-duty spring rate options, allowing you to choose based on your typical riding weight. They are finished in a sleek black to complement your bike's aesthetics. Progressive backs these shocks with a Limited Lifetime Warranty, and they're made right here in the USA, giving you confidence in their build quality and durability for years to come.
