Fox 2.0 Performance Series IFP Technology:

• Internal Floating Piston (IFP): Separates the shock oil from a high-pressure nitrogen gas charge, eliminating oil aeration for consistent, fade-free damping performance
• Aluminum shock body: Impact-extruded aluminum construction dissipates heat significantly faster than conventional steel bodies, extending shock life and maintaining performance under demanding conditions
• Race-proven damping control: Delivers a comfortable on-road ride while providing predictable, controlled handling in off-road and rough-terrain situations
• Rust-resistant construction: Built to withstand the elements for long-term durability
• Precision valving: Factory-tuned valving optimized specifically for Cognito lift height applications

Key Features:

• Designed for use with Cognito 4-inch lift configurations on 2017–2023 Ford F-250/F-350 4WD
• Fox 2.0 smooth body monotube design for superior heat management
• Maintains adequate suspension droop travel for superior ride quality
• Direct bolt-on installation — no cutting or fabrication required
• Made in the USA
• Backed by Cognito Motorsports' limited lifetime warranty to the original purchaser

Whether you're replacing a worn shock in an existing Cognito lift system or completing a custom build, the 220-91045 delivers the performance and durability expected from the Fox and Cognito Motorsports partnership. Sold as a single front shock absorber.
