Restore and enhance your Subaru STI's handling performance with the KYB Gas-a-Just Monotube Shock Absorber. Designed as a direct OE monotube replacement, the Gas-a-Just delivers fade-free operation, improved steering response, and consistent ride control—making it a top choice for drivers seeking both comfort and performance.
This advanced shock features two independent working chambers: one for hydraulic damping and another with high-pressure nitrogen gas separated by a floating piston. This design prevents aeration, eliminates fade, and ensures instant response under all driving conditions—whether you're on a daily commute or carving corners.
