The FOX QS3-QSR shock utilizes a gas-charged mono-tube design featuring an internal floating piston (IFP) and a 1.5-inch 6061-T6 aluminum body with type III hard anodizing. The 5/8-inch shaft is constructed from low-friction, super-finished hard chrome to support advanced high-flow, deflective speed-sensitive damping. This unit is fully rebuildable and re-valvable, ensuring long-term serviceability, and includes an aluminum remote reservoir for optimized thermal management.
Adjustment capabilities include a model-specific optimized ride tune with QS3 quick-switch settings for both compression and rebound. The assembly features a matte black spring paired with a black anodized preload ring, marked with exclusive preload setting guide marks. Installation and maintenance are supported by included fender mounting hardware and an easy-to-use, non-marring plastic preload adjust wrench.
