What makes these shocks a 'progressive rate'?

Progressive rate springs have coils that are closer together at one end and farther apart at the other. This means the spring rate changes as it compresses, offering a softer initial feel that stiffens up under heavier load or compression.

What is the benefit of gas-charged damping?

Nitrogen gas charging helps prevent the oil inside the shock from foaming under heavy use. This foaming can reduce damping effectiveness, so the gas charge ensures more consistent and reliable performance, especially during spirited riding or when carrying extra weight.

Do these shocks come with mounting hardware?

This product listing is for the shocks themselves. It is recommended to refer to the manufacturer's installation instructions or consult with a technician to confirm if any specific hardware is included or if existing hardware should be reused.

Product Details

These Progressive 412 Series shocks, measuring 11 inches and finished in chrome, are built with a double-wall steel body. This construction contributes to their durability and consistent performance over time. They are designed to be a notable improvement over stock suspension, offering smoother damping thanks to their nitrogen-charged, multi-stage velocity-sensitive valving.

For riders looking to fine-tune their ride, these shocks include a five-position cam-style preload adjuster. This allows you to easily dial in the suspension to match your riding style or load, whether you're carrying extra gear or just prefer a firmer or softer feel. The progressive rate springs, available in chrome or black, further help adapt to varying conditions and rider weights, making them a solid option for a range of Harley-Davidson Dyna models.

This set is a popular choice for many Harley-Davidson Dyna motorcycles, including models like the Street Bob, Fat Bob, and Dyna Wide Glide. They offer a straightforward way to enhance your bike's handling and comfort.
