What is the main benefit of the 5-position preload adjuster?

The 5-position cam style preload adjuster allows you to fine-tune the suspension's stiffness. This means you can adjust the ride to better suit your weight, riding style, or if you are carrying a passenger or cargo.

What kind of springs are included with these shocks?

These shocks come equipped with progressive rate springs. This type of spring offers a comfortable ride during normal cruising but becomes stiffer as it is compressed, providing better support during harder riding or when carrying extra weight.

Are these shocks suitable for heavy loads?

Yes, the progressive rate springs and adjustable preload are designed to accommodate different loads. You can adjust the preload to compensate for heavier riders or cargo, ensuring a more stable and controlled ride.

Product Details

Progressive is known for making suspension components that offer a great balance of performance and value, and their 412 Series shocks are a prime example. If you're looking to improve the ride quality and handling on your Harley-Davidson, these 13-inch chrome shocks are a solid option. They're built with a doublewall steel body for durability and feature nitrogen-charged, multi-stage valving to ensure smooth and consistent damping, whether you're cruising down the highway or navigating city streets.

What really makes these shocks stand out is their adjustability. You get a five-position cam-style preload adjuster, which means you can easily dial in your suspension to match your riding style and load. Whether you're a lighter rider or carrying a heavy load, you can fine-tune the ride for optimal comfort and control. The progressive rate springs offer a comfortable ride when you're just cruising, but they stiffen up as needed when you encounter bumps or need to handle more aggressively.

These shocks fit a wide range of Harley-Davidson models, including popular bikes like the Road King, Street Glide, and Electra Glide. The chrome finish and progressive rate springs give your bike a classic look while providing an improved riding experience. They are a well-built upgrade that offers a noticeable difference in how your motorcycle handles.
