RS*R XBIJT304M Best-i Jouge Coilover Kit

The RS*R Best-i Jouge Coilover Kit (XBIJT304M) is a premium, fully adjustable coilover system engineered for crossover and compact SUV platforms. The "Jouge" name—Japanese for "up and down"—reflects this kit's standout capability: the ability to raise ride height above stock for increased ground clearance or lower it for a sportier street stance, all from the same system.

Built on RS*R's acclaimed Best-i platform, the Jouge coilovers feature a monotube damper construction that is hand-assembled in Japan. A 36-way adjustable damping system allows precise tuning to match your driving style, whether you're navigating city streets, cruising highways, or exploring light off-pavement terrain. Ride height adjustment is intuitive and can be done in the field.
