Product Description

The FOX 98450759 is a 2.0 Adventure Series IFP rear shock engineered for 2001-2025 Chevrolet and GMC Silverado/Sierra 2500HD and 3500HD trucks, and 2013-2026 Ram 3500 4WD models running 2-3" rear lift. Built in collaboration with Zone Offroad and valved for heavy-duty truck applications, it uses FOX's proven monotube architecture to deliver reliable, fade-free damping under load - whether towing, hauling, or running demanding off-road terrain. The Internal Floating Piston completely separates the shock oil from the nitrogen gas chamber for consistent performance in all conditions.

The 2.0" 6061-T6 aluminum body pairs with CNC-machined billet components and a 5/8" hard chrome-plated shaft for a construction that handles the stress of heavy-duty truck use mile after mile. JM92 suspension fluid ensures stable damping from cold starts to sustained off-road heat, while the thick silver powder coat protects against road grime and corrosion. Sold individually - two units are required for a complete rear axle upgrade.
