Smooth Out The Ride Without Changing Your Stance

If you’re keeping your 2011-2019 Silverado or Sierra 2500HD/3500HD close to stock height but still want serious performance, the FOX 987-24-030 front shock is the upgrade worth making. It’s built for trucks with 0 to 1 inch of front lift, giving you the extra control and comfort you need without raising your ride. You’ll immediately notice how much smoother the front end feels, especially when rolling over bumps, potholes, or uneven roads. FOX’s Hydraulic Top Out system works behind the scenes to take the sting out of full extension, which makes a huge difference when you're running heavier tires or hitting backroads more often. Whether you're hauling tools to the jobsite or heading up a gravel trail for the weekend, this shock helps keep the ride planted and comfortable. And with its sleek aluminum body and race-ready design, it doesn’t just feel better, it looks the part too. It’s a no-compromise option for truck owners who want capability and comfort without needing a big lift.

Tuned For Precision On And Off The Pavement

The FOX 987-24-030 Performance Series front shock is engineered to give your GM HD truck consistent and responsive control within a 0-1 inch lift range. At the core is a 2.5-inch impact-extruded aluminum body with a clear anodized finish that sheds heat and resists corrosion over time. Internally, it uses a high-flow piston combined with an Internal Floating Piston (IFP) design to maintain precise damping by separating shock oil from high-pressure nitrogen. The Hydraulic Top Out piston adds position-sensitive rebound damping, especially helpful for preventing harsh top-outs during rapid suspension travel. This technology becomes especially valuable if you've added heavier wheels and tires or regularly navigate rugged roads. The 5/8-inch hard chrome shaft adds durability and long-term wear resistance while maintaining a smooth stroke under pressure. FOX also incorporates application-specific valving tailored for the 2011-2019 Silverado and Sierra HD platforms, ensuring a properly balanced response. The result is a shock that’s as capable at highway speeds as it is on uneven terrain.
