The FOX IFP/QSR 2.0 rear shock is a gas-charged mono-tube unit featuring an internal floating piston (IFP) and a 2-inch diameter 6061-T6 aluminum body finished in type III hard anodization. The damper utilizes a 5/8-inch diameter, low-friction, super-finished hard chrome shaft paired with advanced high-flow, deflective disc velocity-sensitive damping. This assembly is engineered with a model-specific optimized ride tune and includes a matte black spring along with a black-anodized preload ring.
Adjustment capabilities include a Hydro-Preload knob offering five positions of adjustment and a 3-position quick switch rebound (QSR) mechanism. The shock is fully rebuildable and re-valvable, ensuring long-term serviceability. It ships with a mounting bracket and is specified for the M8 Softail application with a 13.5-inch standard spring.
