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 is useful for compensating for rider weight, passenger weight, or cargo, ensuring a more comfortable and stable ride.

What makes the damping performance consistent?

These shocks utilize a high-pressure gas charge and multistage velocity-sensitive valving. This combination helps prevent foaming and ensures that the damping action remains smooth and effective across a variety of riding conditions.

Are these shocks suitable for heavy riders or carrying extra weight?

Yes, the 5-position preload adjuster allows you to increase the spring tension to better support heavier loads or riders, providing a more stable and controlled ride.

Product Details

Starting with a doublewall steel body construction, these Progressive 412 Series shocks are built to last and offer a noticeable improvement over stock suspension. The high-pressure gas charge and multistage velocity-sensitive valving work together to provide smooth and consistent damping, which means a more comfortable and controlled ride, whether you're cruising around town or hitting the open road. These shocks are designed to fit a range of Harley-Davidson Sportster models, including popular bikes like the XL1200X Forty-Eight and the XL883N Iron 883.

The real advantage here is the adjustability. You get a five-position cam-style preload adjuster, allowing you to fine-tune the suspension to your specific needs. Whether you're carrying extra gear, riding with a passenger, or just prefer a firmer or softer feel, you can dial it in. This flexibility makes them a solid option for riders of all sizes and riding styles. The black finish and progressive rate springs offer a clean look that complements many Harley-Davidson builds.
