The Yokomo YZ-SSR Rear Spring Set offers three stiffness options to tune the YZ-870C Super Dog Fighter for a variety of track surfaces. These springs let you experiment with rear feel while keeping the original chassis configuration intact.
Choose soft springs to improve rear traction on uneven terrain, medium springs for a balanced setup on mixed layouts, and hard springs when you need sharper response through fast corners. Each rate changes weight transfer and mid-corner behaviour.
Produced to suit the YZ-870C rear mounting arrangement, the YZ-SSR springs install as direct replacements. They are handy for tuning sessions where you want to alter stiffness without swapping other components.
