Looking to increase your vehicle's off-road capability by running larger tires? The new Performance Series 2.5-inch Jeep shocks are designed to provide on-road comfort with performance-minded valving for a connected ride with less vehicle sway. How? Consistent and fade-resistant performance due to high-quality materials: 2.5-inch aluminum bodies and race-developed main piston with a true internal floating piston (IFP) to separate gas and oil. The 2.5-inch piston offers a greater force capability by moving more fluid and increasing damping and is less prone to cavitation. The larger diameter valve assembly improves comfort through a wider dynamic range. This allows for a supple feel as velocity increases when transitioning from crawling to fast trail driving. FOX products are built from aluminum, dissipating heat four times better than conventional materials. All FOX shocks are fully serviceable and resistant to corrosion and harsh environments. Tuned specifically for your vehicle's application. Built-to-last, torture-tested, and race-proven to give a lifetime of great rides.
