Fox 2.0 Performance Series Rear Piggyback Reservoir Shock, 1999-2017 Ford F-250/F-350 Super Duty, 0-1" Lift, 12.1in Ext.

Fits 1999-2017 Ford F-250 and F-350 Super Duty (All Trims) for vehicles with 0-1 inch of rear lift.

The Fox 2.0 Performance Series Piggyback Reservoir shock is engineered to transform your Super Duty's rear suspension performance. By utilizing an external reservoir, this shock increases oil and nitrogen capacity to provide superior heat dissipation and consistent damping under heavy loads or extended off-road use. The 2.0-inch metal-impacted 6061-T6 aluminum body is not only lightweight but dissipates heat four times more efficiently than conventional steel shock bodies.

Inside, a race-developed high-flow piston and application-specific valving deliver a connected ride with reduced vehicle sway and improved bottom-out control. The internal floating piston (IFP) design ensures the oil remains separated from the high-pressure nitrogen gas, preventing aeration and performance fade. Built for durability, the shock features a 5/8-inch hard chrome-plated heat-treated alloy steel shaft and a redundant sealing system designed for long-term reliability in harsh environments.
