What is the main benefit of the progressive rate springs?

Progressive rate springs offer a more adaptable ride. They start softer for better initial compliance over small bumps and then stiffen up as they compress, providing more support during hard acceleration or when carrying heavier loads.

How do I adjust the preload on these shocks?

The shocks feature a five-position cam-style preload adjuster. You can rotate this cam with a basic tool to increase or decrease the spring tension, allowing you to fine-tune the ride height and stiffness based on your riding conditions and load.

What's the difference between standard and heavy-duty springs?

Heavy-duty springs are stiffer and designed for riders who frequently carry a passenger or heavy cargo, or for those who prefer a firmer ride. Standard springs are suitable for lighter riders or those who primarily ride solo with minimal luggage.

Product Details

When you're looking to dial in the suspension on your Harley-Davidson touring bike, the Progressive 412 Series shocks are a solid choice. These 12-inch black shocks are designed to offer a noticeable improvement over stock, providing smoother damping and better control for a more comfortable ride, whether you're cruising solo or carrying a passenger and luggage. They fit a wide range of Harley-Davidson models, including popular bikes like the Road King, Street Glide, and Electra Glide.

The construction here is all-steel with a double-wall body, built to last. Inside, they use nitrogen gas charging and multistage velocity-sensitive valving. What that means for you is consistent damping performance that adapts to road conditions, helping to soak up bumps and keep the tire planted. The five-position cam-style preload adjuster is easy to use, letting you fine-tune the suspension stiffness to match your load and riding style. You can choose between standard or heavy-duty progressive rate springs, available in black or chrome finishes, to get the look and feel you want.
