Enhance your GMC Sierra 2500 or 3500 HD with the FOX Performance Series 2.5-inch lift shock, engineered for superior off-road and on-road performance. Featuring advanced damping technology, these shocks utilize race-proven control to deliver a smooth ride on pavement while providing predictable handling in challenging off-road conditions. The application-specific valving is tuned precisely for your vehicle, helping to maximize both ride comfort and off-road capability. The extended drop-out travel allows for improved articulation, making these shocks ideal for lifted trucks that require reliable performance across diverse terrains.
Constructed from durable 6061-T6 aluminum, the FOX shocks dissipate heat four times better than conventional steel shocks, ensuring consistent and fade-resistant performance even under demanding conditions. The high-flow velocity-sensitive damping adjusts to changing road and trail surfaces for optimal control. Incorporating a race-developed main piston and a true internal floating piston (IFP), these shocks effectively separate gas and oil, contributing to smooth operation and longevity. The fully rebuildable design allows for easy tuning and maintenance, extending the life of your suspension components.
Additional features include a 5/8-inch hard chrome shaft for corrosion resistance and durability, hydraulic top-out (HTO) piston to prevent harsh bottoming out, and a clear-anodized finish on the aluminum body for enhanced corrosion resistance. These shocks are built to endure harsh environments and rigorous use, making them a dependable upgrade for serious off-road enthusiasts. Fully serviceable and designed for longevity, FOX Performance Series shocks provide a balanced combination of on-road comfort and off-road capability, ensuring your vehicle performs at its best in any situation.
