What makes this shock 'application-specific' if it's universal?

The 'application-specific tune' refers to the internal valving. FOX engineers this valving based on the typical weight and suspension travel characteristics of common trucks and SUVs, aiming for a balanced performance across various vehicles in that class.

Can I adjust the settings on this shock?

Yes, this FOX shock is fully rebuildable and re-tunable. This means you can have the internal valving adjusted by a professional to better suit your specific driving needs or modifications.

What does the 'IFP' in the shock name stand for?

IFP stands for Internal Floating Piston. This piston separates the shock oil from the nitrogen gas charge, which helps prevent oil aeration and foaming, leading to more consistent damping performance.

About this part

Product Details

When you're looking to get more out of your truck or SUV's suspension, especially when hitting rougher terrain, upgrading your shocks is a smart move. This FOX 2.5 Performance Series shock absorber is built to make a real difference, offering a more comfortable ride on the street and better control when you're off the beaten path.

This shock uses a 2.5-inch impact-extruded 6061-T6 aluminum body, which is tough and helps with heat dissipation. Inside, it features high-flow velocity-sensitive damping that adjusts automatically to the terrain, giving you a predictable feel. The internal floating piston (IFP) separates the oil and gas, preventing aeration and maintaining consistent performance. Plus, the Hydraulic Top Out (HTO) piston helps prevent the suspension from topping out harshly on compression. It's also fully rebuildable and re-tunable, so you can keep it performing its best for a long time. The 5/8-inch hard chrome shaft is strong and resists corrosion, ensuring durability.

This shock comes with an application-specific tune, meaning it's valved to work well with the typical setup of trucks and SUVs. While it's a universal shock, it's designed to be a solid option for improving your vehicle's overall suspension performance.
