Fox 2.0 Performance Series Reservoir Rear Shock

1984–2001 Jeep Cherokee XJ / 1997–2006 Jeep Wrangler TJ

Built to deliver consistent performance on and off the road, the Fox 2.0 Performance Series shock combines proven race-inspired engineering with a durable, bolt-on design. The aluminum-bodied Performance Series 2.0 smooth body shock delivers FOX’s industry-leading performance in an affordable, hassle-free package, making it a solid upgrade over factory suspension.

Its heat-reducing design features a metal impact-extruded, clear anodized aluminum body that dissipates heat faster than traditional steel shocks, helping maintain consistent damping under demanding conditions. The addition of an external reservoir increases oil and nitrogen capacity, further improving performance while adding a clean, race-inspired appearance.

Internally, a race-developed high-flow damping piston paired with application-specific valving provides a predictable, controlled ride quality capable of handling rough roads, heavy use, and off-road terrain. Combined with precision CNC-machined 6061-T6 aluminum components and a black anodized reservoir mounting clamp, this shock is built for both performance and durability.

Key Features

• 2.0" impact-extruded aluminum body for improved heat dissipation
• External reservoir increases oil and nitrogen capacity
• High-flow piston design for consistent damping performance
• Application-specific valving for balanced ride quality
• Clear anodized body with corrosion resistance
• CNC-machined billet aluminum components
• Bolt-on design with race-inspired performance

Performance Benefits

The Fox 2.0 Performance Series reservoir shock is engineered to provide superior control and stability across varying terrain. The increased fluid capacity from the external reservoir helps reduce shock fade during extended use, making it ideal for both daily driving and aggressive off-road conditions.

Construction & Design

Constructed from 6061-T6 aluminum, the shock body is lightweight and highly resistant to corrosion. The clear anodized finish enhances durability, while the 5/8" hard chrome plated, heat-treated alloy steel shaft ensures strength under load. A redundant sealing system with main, wiper, and scraper seals helps protect against dirt and debris, extending service life.
