Fits select 1994-2013 Dodge Ram 1500, 2500, and 3500. These Fox 2.0 Performance Series Smooth Body IFP shocks are engineered to transform your truck's ride quality and off-road capability. Designed for vehicles with 0-2 inches of front lift, these shocks utilize a metal-impacted 6061-T6 aluminum body to dissipate heat four times faster than conventional steel shocks, significantly reducing damping fade during sustained use.

The internal floating piston (IFP) design separates the shock oil from the high-pressure, nitrogen-charged gas chamber. This elimination of oil aeration ensures consistent, predictable valving performance regardless of terrain. Every component, from the CNC-machined black anodized aluminum accents to the heat-treated spherical bearings, is built for durability and is fully serviceable to maintain peak performance for the life of your vehicle.
