Advanced Shock Absorber. The FOX Performance Series 4.9in IFP is a coil-over and smooth-body shock absorber engineered specifically for select Ford F-150 models. It enhances off-road capability and on-road comfort by providing precise handling and consistent damping, ideal for navigating rough terrain or towing. This product helps improve ride quality and vehicle control while extending suspension performance.

Construction and Appearance. Made from impact-extruded and CNC-machined 6061-T6 clear anodized aluminum, this shock features a corrosion-resistant one-piece body and black anodized billet aluminum components. The internal floating piston (IFP) design separates oil from high-pressure nitrogen gas for consistent damping and reduces cavitation. The exterior finish is clear anodized, offering durability and resistance to wear.

Installation. This shock is designed as a bolt-on replacement requiring no drilling, simplifying installation. Vehicle-specific valving ensures optimal performance without the need for additional modifications.

Warranty. Comes with a limited lifetime warranty for long-term reliability and serviceability. Application. Fits 21-26 4WD Ford F-150 models, excluding Raptor, Hybrid, and Tremor submodels.
