About this part

Product Details

Progressive Suspension is well-known for developing some of the first aftermarket shocks for the popular Harley-Davidson Softail chassis, and they continue to refine their designs. These 422 Series Heavy Duty shocks are built for that legacy, offering a significant upgrade over stock for riders who carry extra weight or ride two-up. They feature a high-pressure gas charged monotube design, which helps maintain consistent damping performance even under demanding conditions.

What really sets these shocks apart is their adjustability. You can dial in the ride height anywhere from stock down to 2 inches lower, letting you achieve that perfect stance. Plus, the spring preload is adjustable, so you can easily compensate for different rider weights or cargo loads, ensuring a comfortable and stable ride. The chrome shroud gives your Softail a classic, clean look that complements many custom builds. This Heavy Duty version is specifically recommended for riders who frequently carry a passenger or heavy gear.

These shocks fit a range of Harley-Davidson Softail models from 1989 through 1999, including popular bikes like the Heritage Softail Classic, Fat Boy, and FXST Softail Standard. They come with a 1-year warranty from Progressive Suspension, giving you peace of mind with your investment.
