Construction & Design
The ER Series coilovers are engineered with durability and performance in mind. The mono-tube damper design ensures consistent damping response by maintaining uniform pressure and reducing cavitation. The twin-piston linear design enhances fluid flow and shock absorption, delivering smooth yet firm control over suspension movement.
Remote reservoirs increase oil volume and surface area for faster heat dissipation, which is critical during aggressive driving or track sessions to prevent fade and maintain consistent damping. High-quality materials and precision manufacturing processes guarantee long-lasting performance and reliability under demanding conditions.
Installation & Fitment
These coilovers are designed as a direct fit for 2011–2023 Chrysler 300C, 300S, Dodge Challenger, Charger, and SRT-8 models, excluding SCAT Pack, Hellcat, and Demon trims. Installation typically requires standard suspension tools and moderate mechanical knowledge. The system includes all necessary components for a complete suspension upgrade without the need for additional modifications.
Adjustments for ride height, compression, and rebound can be made externally, allowing for easy tuning without disassembly. Alignment is recommended after installation to maximize handling benefits and tire wear.
