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

The 5-position cam-style preload adjuster allows you to easily fine-tune the suspension's stiffness. This is useful for adjusting the ride to match your weight, riding style, or if you're carrying a passenger or cargo.

Are these shocks filled with gas?

Yes, these shocks are high-pressure gas charged. This helps ensure consistent damping performance by preventing the oil from foaming, even under demanding conditions.

What is the difference between standard and heavy-duty springs?

While not specified for this exact part number, Progressive typically offers standard springs for average rider weight and heavy-duty springs for riders who carry heavier loads or prefer a firmer ride. Check the specific application notes for your model if available.

These 412 Series shocks are a prime example, designed to give your Harley-Davidson a smoother, more controlled ride. They fit a wide range of Harley models, including popular bikes like the Road King, Street Glide, and Road Glide, making them a solid option for many riders looking to upgrade their suspension.

The construction here is solid, featuring a doublewall steel body that's built to last.

This means you get a more comfortable and predictable feel from your bike. Plus, the five-position cam-style preload adjuster lets you easily fine-tune the suspension to match your riding style and load, whether you're riding solo or two-up.

With their classic chrome finish and progressive rate springs, these shocks not only perform well but also add a custom look to your motorcycle. They are a straightforward upgrade that can make a real difference in your riding experience.
