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

The five-position cam-style preload adjuster allows you to easily change the spring tension. This lets you fine-tune the suspension's stiffness to match your riding style, whether you're carrying a passenger or riding solo.

Are these shocks filled with gas?

Yes, these shocks are high-pressure gas charged. This helps maintain consistent damping performance by preventing the oil from foaming, especially during extended use or over rough terrain.

What is the difference between Standard and Heavy-Duty springs?

While these specific shocks feature progressive rate springs, Progressive offers both Standard and Heavy-Duty spring options for some 412 models. Heavy-Duty springs are typically designed for riders who carry heavier loads or prefer a firmer suspension feel.

Product Details

If you're looking to give your Harley-Davidson a smoother ride and better handling, these Progressive 412 Series shocks are a solid option. They fit a wide range of Harley models, including popular bikes like the Road King, Street Glide, and Electra Glide. These shocks are designed to be a direct replacement for your stock units, making the upgrade straightforward.

What makes these shocks stand out is their well-built, double-wall steel body construction. Inside, they use a nitrogen-charged, multi-stage valving system that helps deliver consistent damping, so you get a more controlled feel over bumps and rough roads. You can also fine-tune your ride using the five-position cam-style preload adjuster, letting you set the suspension stiffness whether you're riding solo or with a passenger and luggage.

These shocks come with progressive rate springs in a bright chrome finish, and you can also find them with black springs or optional full show chrome covers for a different look. They're a popular choice because they offer a noticeable improvement in ride quality without breaking the bank.
