Overview:

The ST Suspensions XA Coilover Kit is a premium suspension upgrade designed specifically for Dodge Challenger models from 2011 through 2023, excluding SRT variants. Engineered in collaboration with KW Automotive, this coilover kit offers more than just adjustable ride height—it provides full rebound damping control to tailor your driving experience. Whether you seek improved handling for spirited driving or a more comfortable ride for daily use, the ST XA coilovers deliver enhanced agility, reduced body roll, and a striking lowered stance that transforms your Challenger’s presence on the road.

Ideal for enthusiasts who demand both performance and versatility, the XA coilover kit allows you to fine-tune suspension stiffness quickly and easily, adapting to various driving conditions without compromising comfort or control.

Key Features:

The ST Suspensions XA Coilover Kit incorporates advanced technology and thoughtful design to elevate your Dodge Challenger’s suspension performance:

• Adjustable Front Lowering Range: 1.2" to 2.6"
• Adjustable Rear Lowering Range: 1.8" to 3.1"
• Individual rebound damping adjustment using KW damping technology
• Damping adjustment accessible at the top of the chromed piston rod for quick tuning
• Galvanized steel construction for corrosion resistance and durability
• Pressure-resistant damper housings for consistent performance under demanding conditions
• Continuous threaded strut design allows height adjustment even when installed
• Improves handling precision, reduces body roll, and enhances track stability
• Compatible with both rear-wheel and all-wheel drive Dodge Challengers (non-SRT)

Construction & Design:

The ST XA coilovers are built with high-quality galvanized steel components that resist corrosion and ensure long-lasting durability. The pressure-resistant damper housings maintain consistent damping performance, even under aggressive driving or track conditions. The continuous thread design on the struts allows for precise lowering adjustments without the need to disassemble the suspension, making installation and tuning straightforward. The chromed piston rod not only adds corrosion resistance but also provides a smooth surface for the damping adjustment mechanism, enabling quick and reliable tuning of rebound forces.

Performance & Sound

By enabling individual rebound damping adjustment, the ST XA coilover kit allows you to customize your Dodge Challenger’s handling characteristics. Increasing rebound force enhances track stability and reduces body roll, delivering a sharper, more controlled driving experience. Conversely, decreasing rebound force softens the suspension for improved ride comfort during everyday driving. This adaptability makes the XA coilovers suitable for a wide range of driving styles, from aggressive street performance to comfortable cruising. While primarily focused on handling, the improved suspension dynamics also contribute to a more connected and responsive feel behind the wheel.

Installation & Fitment:

The ST Suspensions XA Coilover Kit is designed for direct fitment on 2011–2023 Dodge Challenger models equipped with rear-wheel or all-wheel drive, excluding all SRT variants. Vehicles with electronic damping control require deactivation of the system prior to installation; a deactivation kit is available separately from KW (part #68510314). Installation involves replacing the factory struts and springs with the coilover assembly, and the continuous thread design allows for height adjustments without removing the coilovers. Professional installation is recommended to ensure proper setup and alignment.

What's Included:

• Complete coilover system (front and rear coilovers)
• Adjustable spring plates for height tuning
• Rebound damping adjustment hardware integrated on piston rods
• Installation instructions
• ST Suspension’s Limited Manufacturer’s Warranty

Ideal For:

The ST Suspensions XA Coilover Kit is perfect for Dodge Challenger owners seeking a versatile suspension upgrade that balances performance and comfort. It is ideal for enthusiasts who want to lower their vehicle for improved aesthetics and handling without sacrificing ride quality. Whether you enjoy spirited driving on back roads, occasional track days, or simply want a more responsive and agile daily driver, the XA coilovers provide the adjustability and durability to meet your needs.

Important Notes

• Not compatible with any Dodge Challenger SRT models.
