Fox Factory Race Series 2.0 X2 DSC Adjustable Coilover Reservoir Shock Kit for Dodge Charger & Challenger (2011–2023).
The Fox Factory Race Series 2.0 X2 DSC Adjustable Coilover Reservoir Shock Kit (Part #883-30-000) represents the most advanced suspension solution FOX offers for 2011–2023 Dodge Charger and Dodge Challenger platforms. Designed for drivers who demand true motorsport-level adjustability without sacrificing street drivability, this kit transforms modern Mopar muscle into a precision-handling machine that performs on the street, track days, roll racing events, and competitive environments.
Built using FOX’s racing-derived X2 technology, this system delivers an unmatched combination of ride quality, control, and tuning flexibility—ideal for performance-focused daily drivers, weekend track cars, and high-horsepower builds.
Factory Race Series Engineering for Modern Mopar Muscle.
Unlike entry-level coilovers, the FOX Factory Race Series 2.0 X2 shocks are developed using the same engineering principles found in professional motorsports. FOX ride engineers extensively tested Dodge Chargers and Challengers on public roads and racetracks to dial in vehicle-specific valving that improves balance, predictability, and stability across a wide range of driving conditions.
By converting the rear suspension to a true coilover configuration, FOX improves suspension motion ratio, enhances ride control, and makes ride height adjustments straightforward—without compromising suspension travel or daily usability.
X2 DSC Technology with 4-Way Independent Adjustment.
At the core of this system is FOX’s X2 Dual Speed Compression (DSC) adjuster, delivering 4-way independent tuning:
-
High-Speed Compression (HSC)
-
Low-Speed Compression (LSC)
-
High-Speed Rebound (HSR)
-
Low-Speed Rebound (LSR)
Each circuit offers 24 precise click adjustments, allowing drivers to fine-tune suspension behavior with incredible accuracy. This level of control lets you stiffen the suspension for track use, roll racing, or aggressive canyon driving—then quickly dial it back for a comfortable drive home.
The twin-tube recirculating oil architecture, paired with X2 adjusters, ensures consistent damping performance even under high heat and repeated hard use.
External Reservoirs for Consistent Performance.
The Factory Race Series kit includes external reservoirs with internal floating pistons. These reservoirs:
-
Increase oil capacity for better heat management
-
Reduce damping fade during extended aggressive driving
-
Minimize harshness associated with nitrogen pressure ramp-up
The result is smoother suspension response over rough pavement, curbing, and high-speed impacts—while maintaining precise control at speed.
Ride Height Adjustability for Performance and Stance.
This FOX Factory Race Series coilover kit supports a 0.75–1.5 inch ride height drop, giving Charger and Challenger owners the ability to lower their vehicle for improved center of gravity, sharper turn-in, and a more aggressive stance. The controlled drop improves high-speed stability while preserving suspension geometry for predictable handling.
Built to Survive Track Abuse and Daily Driving.
Every component in the Factory Race Series 2.0 X2 kit is engineered for strength, longevity, and consistency:
-
2.0-inch impact-extruded, CNC-machined 6061-T6 aluminum bodies
-
TYPE III hard anodization to prevent corrosion and wear
-
5/8-inch hard-chromed steel shafts for maximum durability
-
Rubber-isolated spherical bearings for precise feedback without excessive NVH
-
Redundant sealing system (main seal, wiper seal, scraper seal)
-
External reservoir with internal floating piston
This combination delivers a planted, stable feel through inconsistent pavement, aggressive cornering, and repeated high-load driving.
Designed for Street, Track, and Performance Events.
With FOX Factory Race Series suspension installed, Dodge Charger and Challenger owners experience:
-
Significantly improved chassis balance
-
Reduced body roll and pitch
-
Predictable braking and acceleration transitions
-
Increased confidence during high-speed driving
-
Tunable comfort for daily driving and long-distance use
This system is equally suited for street builds, road course track days, roll racing events, and high-performance Mopar applications.
