How do I adjust the spring preload on these shocks?

The spring preload on the Progressive 990 Series shocks is designed to be adjusted by hand. You can turn the threaded collar on the spring perch to increase or decrease the preload, allowing you to set the ride height and sag for your specific needs.

What is the benefit of having adjustable high and low-speed compression damping?

Adjustable high and low-speed compression damping allows for very precise tuning of how the shock absorber reacts to different types of impacts. Low-speed adjustments affect body movements like braking dive and acceleration squat, while high-speed adjustments manage how the shock handles sharp bumps and rough surfaces, leading to improved control and comfort.

Are these shocks sold individually or as a pair?

These Progressive 990 Series shocks are sold as a pair, ensuring you have matching suspension components for both sides of your motorcycle.

Product Details

If you're looking to fine-tune your Harley-Davidson FXR or Sportster's suspension, the Progressive 990 Series Shocks are a top-tier option. These 15-inch shocks are built for riders who want complete control over their ride's feel and performance. They fit a wide range of Harley-Davidson models, including popular FXR and XL variants, giving you the ability to dial in your motorcycle for everything from spirited canyon carving to comfortable cruising.

What sets the 990 Series apart is its extensive adjustability. You get hand-adjustable spring preload, rebound damping adjustment, and even high and low-speed compression damping adjustments, all accessible via easy-to-use knobs. This level of control allows you to precisely tune the shock's response to your riding style and road conditions. The shocks feature a high-pressure monotube design with a deflective disc damping system, which ensures consistent damping performance throughout the entire stroke. This means a more stable and predictable feel, especially when you're pushing the bike. The lightweight aluminum body also helps with heat dissipation and reduces unsprung weight, contributing to better handling.

Progressive builds these shocks by hand in their facility, tuning and dyno-testing each one to ensure it meets their standards. They also include an updated jounce bumper with a captured design to help smooth out hard impacts and prevent bottoming out. If you're serious about getting the most out of your Harley's suspension, these shocks offer a well-built, highly tunable solution.
