Fox Factory 2.5 Performance Series 11.1in Smooth Body IFP Shock (Alum) Std. Travel / Eyelet End

This is the FOX Factory 2.5 Performance Series 11.1-inch smooth body IFP shock absorber, part number 987-24-040. It's built to significantly improve how your truck or SUV handles both on the pavement and when you take it off-road. FOX uses their race-proven damping technology to give you a comfortable ride during daily driving while still offering predictable control when the terrain gets tough.

The shock body itself is made from impact-extruded 6061-T6 aluminum, which is then clear-anodized for corrosion resistance. Inside, it features a high-flow, velocity-sensitive damping system and an internal floating piston (IFP) to help manage fluid and gas separation. This design, along with the application-specific tuning, means the shock responds precisely to changing road conditions. It also has a 5/8-inch hard chrome shaft for durability and is fully rebuildable and re-tunable, so you can adapt it to your specific needs or refresh it down the line.

This shock is designed to be a direct replacement for many trucks and SUVs, offering a notable upgrade in suspension performance. Because it's application-specific, the valving is already set up to work well with your vehicle's weight and suspension geometry.
