RockShox Metric Coil Spring

This spring is designed for metric-sized rear shocks. You must verify that your shock's stroke length falls within the 47.5mm to 55mm range and that the physical length of the spring (134mm) fits your specific shock body.

The spring rate indicates the stiffness of the coil. A 450 lb rating means it takes 450 pounds of force to compress the spring one inch; this is generally suited for riders who need a balance of support and suppleness, but your ideal rate depends heavily on your body weight and frame leverage ratio.

While designed for RockShox metric shocks, it may fit other brands if the inner diameter and physical dimensions align. However, we strongly recommend sticking to the manufacturer's specified spring for your shock to ensure proper fitment and safety.

No, this is a replacement coil spring only. It does not include the spring retainer, preload collar, or any mounting hardware required to install it on your shock.

Coil springs like this one offer a more linear feel and consistent performance regardless of temperature or trail duration. They are often preferred by riders seeking maximum small-bump sensitivity and reliability over the adjustability and weight savings of an air spring.
