Designed specifically for 2001–2024 GM 2500HD and 3500HD 4WD models with 0 to 2 inches of rear lift, this shock blends FOX’s proven off-road capability with the smooth ride comfort you need on the street. At the heart of this shock is a monotube design with an internal floating piston (IFP). What that means in real-world terms is a shock that resists fade, even when you're working it hard over rough terrain or washboard backroads. The IFP separates the shock oil from the high-pressure nitrogen gas, which helps maintain consistent damping and eliminates the foaming or aeration that can cause performance to drop off when things heat up. Premium Construction with High-Quality Hardware The body itself is a 2.0-inch honed, seamless alloy—not only does it look clean with its silver powder coat finish, but it’s built to take abuse. The 5/8-inch chrome-plated, heat-treated steel shaft adds strength and durability, especially important on heavy-duty trucks that see serious mileage or off-road use. One of the standout features here is the quiet nitrile rubber bushings. They allow for solid articulation while keeping noise and vibration to a minimum, which means fewer squeaks and rattles when you're out on the trail—or just navigating pothole-ridden streets. It’s also worth noting that this shock is filled with FOX’s JM92 advanced suspension fluid, which is formulated to handle a wide range of temperatures. So whether you're dealing with winter slush, desert heat, or springtime mud, the damping remains predictable and consistent.
