Overview:

The FOX 2.5in Performance Series Smooth Body IFP HTO Rear Shock is engineered to elevate the driving dynamics of your Jeep Gladiator from 2018 through 2026. Designed for off-road enthusiasts and daily drivers alike, this shock absorber combines race-proven technology with application-specific tuning to deliver a balanced ride. Whether navigating rugged trails or cruising on pavement, it provides superior control, comfort, and durability.

Built to withstand the toughest conditions, this shock enhances your vehicle’s off-road capability by extending drop-out travel while maintaining a connected and stable on-road feel. Its advanced damping system ensures predictable handling and reduces vehicle sway, making it an ideal upgrade for Jeep Gladiator owners seeking improved suspension performance without compromising ride quality.

Key Features:

Every FOX Performance Series shock incorporates cutting-edge technology and premium materials to maximize performance and longevity. Key features include:

• 2.5-inch impact extruded 6061-T6 aluminum shock body for lightweight strength and superior heat dissipation
• Internal Floating Piston (IFP) design that separates gas and oil to prevent cavitation and maintain consistent damping
• Hydraulic Top Out (HTO) piston to reduce harsh top-out impacts and improve ride smoothness
• High-flow velocity-sensitive damping for responsive and adaptable shock absorption
• Application-specific valving tuned precisely for Jeep Gladiator models to optimize on- and off-road performance
• 5/8-inch hard chrome shaft offering enhanced corrosion resistance and durability
• Type II clear-anodized body plating for corrosion protection in harsh environments
• Fully rebuildable and re-tunable design for long-term serviceability and customization

Construction & Design:

FOX shocks are crafted from premium materials to ensure durability and consistent performance. The 2.5-inch shock body is made from impact-extruded 6061-T6 aluminum, a material known for its excellent strength-to-weight ratio and superior heat dissipation—four times better than conventional steel bodies. This helps maintain optimal operating temperatures during demanding use.

The internal floating piston (IFP) separates the nitrogen gas from the hydraulic oil, preventing aeration and fade during extended use. The hydraulic top out (HTO) piston further refines the shock’s behavior by cushioning the upward travel, reducing harshness and improving overall ride quality. The 5/8-inch hard chrome shaft resists corrosion and wear, ensuring long-lasting performance even in challenging off-road conditions.

Installation & Fitment:

This FOX Performance Series rear shock is designed as a direct fit replacement for most Jeep Gladiator models from 2018 to 2026, including popular trims such as the Rubicon, Mojave, Overland, Sport, Willys, and special editions like the 80th Anniversary and Launch Edition. Installation requires no modifications, making it a straightforward upgrade for enthusiasts looking to enhance their suspension system.

Professional installation is recommended to ensure proper torque specifications and alignment. The shock’s rebuildable nature also allows for future servicing and tuning adjustments to match evolving driving preferences or terrain challenges.
