Product Details

If you're looking to improve the ride and handling of your Harley-Davidson Sportster, these Progressive 412 Series shocks are a solid option. Designed to fit a wide range of Sportster models, these 12.5-inch shocks offer a noticeable upgrade over stock suspension. They feature a doublewall steel body construction that's built to last, housing a nitrogen-charged damping system with multistage velocity-sensitive valving for smooth and consistent control over bumps and road imperfections.

What really makes these shocks stand out for the price is the adjustability. You get a five-position cam-style preload adjuster, which lets you easily dial in your suspension to match your riding style and load. Whether you're riding solo or carrying a passenger, or if you prefer a firmer or softer feel, you can fine-tune the ride. The chrome finish and chrome springs give your bike a classic, clean look that complements many Harley-Davidson styles.

These shocks are a popular choice because they offer a good balance of performance, durability, and value for Harley-Davidson Sportster owners. They are designed to be a direct replacement for your original equipment, making installation straightforward.
