Overview

The FOX Factory Race Series Internal Bypass Rear Shock is engineered specifically for Jeep Gladiator JT models from 2018 through 2026, designed to elevate off-road performance and ride quality for lifted vehicles with 2-3 inch suspension lifts. Drawing from FOX’s championship-winning off-road racing technology, this shock absorber features advanced internal bypass technology that delivers smooth, controlled suspension travel across diverse terrains.

It is ideal for Jeep Gladiator enthusiasts who demand race-level suspension capability without sacrificing daily driving comfort.

Key Features

Built to optimize your Jeep Gladiator’s rear suspension, the FOX Factory Race Series Rear Shock offers the following advanced features:

• Patented Internal Bypass Technology: Allows oil to flow around the piston at specific points, creating multiple damping zones for near-endless suspension travel and superior adaptability to varying terrain.
• Application-Specific Valving: Precisely tuned for Jeep Gladiator weight and suspension geometry to deliver optimal damping control.
• Dual Speed Compression Adjustment: Enables fine-tuning of compression damping for both low- and high-speed impacts, improving ride comfort and vehicle control.
• Race-Developed Shock Piston: Works in harmony with the internal bypass system to provide smooth, consistent performance during demanding off-road use.
• Robust Construction: Features durable 3-inch and 2.5-inch aluminum shock bodies, 7/8” hardened shafts with redundant seals, and external cactus cooler reservoirs for superior heat dissipation.
• Black Anodized CNC Machined Aluminum Components: Deliver strength, corrosion resistance, and a sleek, high-performance appearance.
• External Reservoir System: Enhances heat management to maintain consistent damping performance during extended off-road sessions.
• Multiple Internal Damping Zones: Provide a balanced ride that adapts dynamically to changing terrain and driving conditions.

Construction & Design

FOX Factory Race Series shocks are crafted from premium materials engineered to endure the harshest off-road environments. The aluminum shock bodies dissipate heat more efficiently than traditional steel, reducing shock fade and maintaining consistent damping performance. The black anodized finish protects against corrosion and wear, ensuring long-lasting durability and a professional appearance.

The hallmark internal bypass system dynamically modulates damping forces throughout the suspension stroke, mimicking the feel of extended travel for improved traction and a smoother ride. The inclusion of cactus cooler reservoirs further enhances heat dissipation, preventing overheating during intense off-road use and preserving shock performance.
