52mm Monotube Coilover Kit

The Riaction Sport Coilovers offer a performance upgrade for street cars, focusing on achieving a lower ride height, enhanced handling dynamics, and improved overall comfort. Key features of these coilovers include full-length ride height adjustment, allowing for precise customization of your vehicle's stance. The damping can be tuned across 32 distinct levels, enabling drivers to fine-tune suspension response for various driving conditions. The internal design incorporates a mono-tube damper for consistent performance and a seamless 52mm electroplated carbon steel shock body for robust construction. The coilovers are built with a 44mm high-flow CNC 6061 aluminum piston and a thinned CNC 6061 aluminum floating piston, paired with polyurethane oil seals for longevity. The springs are made from SAE9254 cold-wound steel, with specified rates of 12K for the front and 8K for the rear. The suspension fluid used is a 7.5w compounded type, and the entire unit is designed to be fully rebuildable, ensuring long-term usability and maintenance. These Riaction Sport Coilovers are specifically designed to fit the 1990-2000 Lexus LS400 and come with a 2-year warranty.
