Upgrade the on-road comfort and off-road control of your 2020-2024 Chevy Silverado or GMC Sierra 2500/3500 4WD with FOX Performance Series 2.5 IFP Front Shocks featuring Hydraulic Top Out (HTO) technology. Built for overland and off-road builds that demand consistent performance, these mono-tube shocks use an internal floating piston to separate shock oil from the high-pressure, nitrogen-charged gas chamber—eliminating oil aeration and delivering maximum performance from the factory-tuned, precision valving. The result is a predictable, fade-free ride capable of handling the roughest conditions, whether you're crawling a trail, hauling gear to camp, or putting miles down on the highway.
Hydraulic Top Out (HTO) technology adds position-sensitive rebound damping that works on and off the pavement, giving you usable control through the full range of suspension travel. If your truck is already running a BDS suspension system, this is a direct performance upgrade designed to take it further.
