Mercedes M-Class W164 Coilovers (2005–2011) – GT-1

Riaction Sports Coilovers for the 2005–2011 Mercedes-Benz M-Class (W164) are designed to provide improved handling, reduced body roll, and adjustable ride height while maintaining comfort for everyday street driving. Developed for the W164 chassis, this suspension system offers greater control over suspension movement and vehicle stability, particularly during cornering, braking, and highway driving. The Mercedes-Benz M-Class is a heavier SUV platform, making suspension control an important factor in maintaining predictable handling. Riaction Sports Coilovers feature 32 levels of damping adjustment, allowing drivers to fine-tune suspension firmness to suit their driving preferences and road conditions. Full-length ride height adjustment provides flexibility for lowering the W164 while maintaining usable suspension travel. The monotube damper design incorporates a 44mm high-flow CNC 6061 aluminum piston, multi-thickness valving shims, and a low-gas-pressure internal system to provide consistent damping response. Combined with SAE9254 cold-wound springs and 7.5W compounded suspension fluid, these components help manage weight transfer, reduce excessive chassis movement, and maintain a controlled ride during daily driving. Each kit features seamless 52mm electroplated carbon steel shock bodies, precision-machined aluminum internal components, and polyurethane oil seals for durability and consistent performance. The dampers are fully rebuildable for long-term serviceability, and every Riaction Sports Coilover kit includes a 2-year factory warranty against manufacturing defects.
