• Race-proven internal valving technology ensures consistent damping performance under varied driving conditions.
• Durable construction with high-quality materials resists corrosion and wear for long-lasting reliability.
• Direct bolt-on fitment for 2014–2018 Ram 1500 3.0L EcoDiesel and 2019–2021 Ram 1500 Classic 3.6L V6 and 5.7L Hemi engines, ensuring easy installation without modifications.
• Optimized for both off-road and street use, providing a smooth ride without sacrificing performance.
• Adjustable coil springs allow for ride height customization and improved load handling.
• Sealed nitrogen gas-charged shocks reduce fade and maintain consistent damping during extended use.

Construction & Design

The FOX Factory Series coilovers are built with precision-engineered components crafted from premium materials to withstand the rigors of off-road and daily driving. The shock bodies are constructed from lightweight yet robust aluminum alloy, providing excellent heat dissipation and corrosion resistance. The coil springs are designed to deliver optimal spring rates that balance comfort and control, while the DSC adjuster knob is ergonomically positioned for easy access and precise tuning.

Each coilover features FOX’s signature internal valving system, which is calibrated to provide smooth compression and rebound characteristics. The nitrogen gas charge inside the shocks minimizes cavitation and shock fade, ensuring consistent performance even under demanding conditions. The overall design emphasizes durability, adjustability, and compatibility with Ram 1500 suspension geometry.

Installation & Fitment

This coilover set is engineered for direct bolt-on installation on select Ram 1500 models, including 2014–2018 3.0L EcoDiesel and 2019–2021 Ram 1500 Classic with 3.6L V6 or 5.7L Hemi engines. Installation requires standard hand tools and basic mechanical knowledge, with no need for cutting or welding. The coilovers replace the factory rear shocks and springs, maintaining proper suspension geometry and ride height.

For best results, it is recommended to have the installation performed by a professional or experienced technician familiar with Ram suspension systems. After installation, adjusting the DSC settings allows you to dial in the suspension response to match your driving style and terrain.
