Model-specific optimized ride tune QS3-R Piggyback Shocks feature 3 position quick switch rebound and compression control (soft, medium, firm)

Upgrade your Harley Davidson with the FOX IFP QSR Shocks designed specifically for Dyna and Fat Bob models. These shocks feature an innovative piggyback design with model-specific optimization to deliver superior ride quality and handling. Equipped with 3-position quick switch rebound and compression control (soft, medium, firm), these shocks allow for quick adjustments to match your riding style and terrain. The gas-charged mono-tube or aluminum piggyback versions both incorporate an internal floating piston, ensuring consistent damping performance under various conditions.
Constructed from durable 1.5-inch 6061-T6 aluminum with Type III hard anodized finish, these shocks are built to withstand rigorous use while remaining lightweight. They are fully serviceable and rebuildable, enabling maintenance and prolonging their lifespan. The high-flow, velocity-sensitive damping system with deflective disk technology provides smooth, controlled compression and rebound, enhancing ride comfort and stability. Hand-adjustable spring preload allows for easy customization based on rider weight and load, providing a tailored riding experience.
The 1/2-inch low friction, super-finished hard chrome shaft reduces stiction and wear, contributing to consistent performance over time. The carbon black spring complements the shock’s aesthetic and offers reliable support. Laser-etched FOX logos give a premium appearance, while the recommended load capacity of up to 240 pounds ensures optimal operation for most riders. These shocks are designed for easy installation and are a perfect upgrade for Harley Davidson owners seeking improved ride quality, performance, and adjustability.
