How does the Remote Adjustable Preload (RAP) system work?

The RAP system uses a remote adjuster, typically located near the passenger footpeg. This allows you to easily turn a knob or mechanism to change the spring preload without needing to remove the shock or use special tools.

What is the difference between Standard and Heavy Duty versions of these shocks?

The Heavy Duty version is built to handle more demanding use, such as carrying heavier loads, a passenger, or for riders who prefer a firmer suspension feel. It generally offers more damping capacity.

Can I adjust the ride height with these shocks?

Yes, these shocks are adjustable in length, allowing you to lower the rear of your motorcycle from stock height down to 2 inches lower. This lets you customize the bike's stance and handling.

Product Details

Progressive Suspension is well-known for making motorcycle suspension components that improve ride quality and handling. These 422 Series Heavy Duty shocks with RAP (Remote Adjustable Preload) are designed to make adjusting your Harley Softail's suspension much easier, especially on models where the stock shocks are tucked away under the frame. This means you can quickly fine-tune your ride for different conditions, like carrying a passenger or extra gear, without a struggle.

These shocks feature a high-pressure gas charged monotube design, which helps maintain consistent damping performance even when the suspension is working hard. The chrome finish gives them a clean look that complements many Harley-Davidson models. A notable feature is the RAP system, with its remote adjuster conveniently located behind the left passenger peg, allowing for easy preload adjustments. You can also adjust the length of these shocks, from stock height down to 2 inches lower, giving you flexibility in setting up your bike's stance and handling characteristics. This set is the Heavy Duty version, built for more demanding use.

This set fits a range of Harley-Davidson Softail models from 1989 through 1999, including popular bikes like the Heritage Softail Classic, Fat Boy, and FXST models. They come ready to install and offer a significant improvement in ride comfort and adjustability over stock components.
