RockShox Metric Coil Spring

This spring is designed for RockShox metric shocks with a stroke length between 57.5mm and 65mm. Always verify your shock's specific stroke length and inner diameter requirements before purchasing, as coil springs are not universally interchangeable.

The 650 lb spring rate refers to the stiffness of the coil, meaning it takes 650 pounds of force to compress the spring one inch. A higher spring rate like this is typically suited for heavier riders or those who prefer a firmer, more supportive feel that resists bottoming out on big hits.

While it is engineered for RockShox metric systems, compatibility depends entirely on the inner diameter of the spring and the physical dimensions of your shock body. We recommend sticking to the manufacturer's specifications to ensure proper fitment and safety.

No, the 151mm length is specific to certain metric shock configurations. You must match the spring length to your shock's stroke and eye-to-eye measurement to ensure the spring is properly preloaded and does not bind or rattle.

At 680.39 grams, this is a standard steel coil spring. While it will add more weight compared to an air spring setup, the trade-off is the consistent, linear performance and reliability that coil springs are known for on rough terrain.
