What does the QS3 adjustment do?

The QS3 Quick Switch offers three distinct compression damping settings. This allows you to easily adjust the shock's stiffness to suit different riding conditions, from smooth trails to rougher terrain, without needing special tools.

Why is the aluminum body important for this shock?

The 6061-T6 aluminum body is chosen for its strength-to-weight ratio and excellent heat dissipation properties. This helps the shock perform consistently under heavy use and resist corrosion, contributing to its overall durability.

What is the benefit of the Remote Reservoir (RT)?

The remote reservoir increases the shock's oil capacity and helps to dissipate heat more effectively. This leads to more consistent damping performance, especially during prolonged or aggressive use, and helps prevent shock fade.

About this part

Product Details

The 2.0-inch diameter body of this Fox Factory Series coil-over shock absorber is machined from a solid billet of 6061-T6 aluminum, offering a strong yet lightweight foundation for serious suspension performance. This material choice not only contributes to heat dissipation but also resists corrosion, ensuring longevity even in demanding conditions. The QS3 Quick Switch 3-position compression adjustment allows you to fine-tune your ride for different terrains or riding styles without needing specialized tools, making it incredibly versatile for riders who encounter varied landscapes.

Inside, the shock utilizes a high-performance damping system designed to manage heat effectively, which is crucial for maintaining consistent damping force during extended use or aggressive riding. The internal floating piston (IFP) separates the shock oil from the nitrogen charge, preventing aeration and ensuring smooth, reliable operation. This coil-over design integrates the spring and shock into a single unit, simplifying installation and providing a clean, integrated look for your suspension setup. The included RT (Remote Reservoir) helps to further manage heat and increase oil volume, providing an improved damping experience over rough terrain.

This shock absorber is a substantial upgrade for vehicles requiring robust suspension components. It's built to handle the rigors of off-road use, providing both improved comfort and enhanced control. When installing, ensure you follow the manufacturer's guidelines for proper mounting and adjustment to get the most out of its advanced features.
