Key Features:

Engineered for precision and durability, the FOX Factory Series Rear Bump Stop Extension offers the following key features:

• Patented internal bypass technology for smooth oil flow and pressure modulation
• Internal Floating Piston (IFP) separates oil from high-pressure nitrogen gas to maintain consistent damping
• Application-specific valving tuned for Jeep Gladiator suspension dynamics
• Constructed from black anodized CNC machined aluminum components for strength and corrosion resistance
• Aluminum body dissipates heat faster than steel, enhancing performance under extreme conditions
• Compatible with FOX Factory Series shocks for a cohesive suspension system
• Designed to create the feel of near-endless suspension travel, improving ride comfort and control
• Robust 7/8” shafts with redundant seals to withstand harsh off-road environments
• Requires minor modifications for installation, ensuring a precise fit on Jeep Gladiator models

Construction & Design:

The FOX Factory Series bump stop extension is crafted from high-grade aluminum, chosen for its excellent heat dissipation and lightweight strength. The black anodized finish not only enhances corrosion resistance but also provides a sleek, durable appearance. Precision CNC machining ensures tight tolerances and consistent performance across all units.

At the heart of the design is FOX’s patented internal bypass technology, which allows oil to flow around the piston during certain parts of the suspension stroke, reducing harshness, while generating high pressure at other points to support the vehicle’s weight effectively. The inclusion of an Internal Floating Piston (IFP) maintains separation between oil and nitrogen gas, preventing cavitation and ensuring consistent damping characteristics even under extreme conditions.

Installation & Fitment:

This bump stop extension is designed specifically for 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. While installation requires some modifications, the process is straightforward for experienced installers and off-road enthusiasts familiar with suspension upgrades.

Proper installation ensures optimal performance and compatibility with existing FOX Factory Series shocks, delivering enhanced suspension travel and improved ride quality tailored to the Gladiator’s unique chassis and off-road capabilities.
