The Fox 2.0 Performance Series Smooth Body IFP (Internal Floating Piston) shock is engineered to transform your heavy-duty truck's suspension performance. By utilizing a 2.0-inch metal-impacted 6061-T6 clear-anodized aluminum body, this shock dissipates heat four times faster than conventional steel shocks, maintaining consistent damping even during heavy use. The internal floating piston architecture separates the shock oil from the high-pressure, nitrogen-charged gas chamber, eliminating oil aeration and providing fade-resistant valving across varied terrain.

Built with race-proven technology, these shocks feature a 5/8-inch hard chrome-plated heat-treated alloy steel shaft and a high-flow piston design. The inclusion of JM92 Advanced Suspension Fluid ensures stable performance in extreme temperatures, while the redundant sealing system and Teflon-lined heat-treated spherical bearings provide long-term durability and quiet operation.
