RockShox Metric Coil Spring

Spring rate is primarily determined by your rider weight, bike leverage ratio, and personal preference for suspension feel. A 450lb spring is a mid-range option; if you find you are bottoming out too easily or the bike feels sluggish, you may need to adjust your spring rate accordingly.

No, this spring is specifically designed for metric shocks with a 37.5-45mm stroke length. You must verify that your shock's stroke and eye-to-eye length match these specifications to ensure proper fit and safety.

Coil springs are generally favored for their consistent performance, linear feel, and low maintenance requirements. Unlike air springs, they are unaffected by temperature changes or seal friction, providing a very supple and predictable ride quality.

Installing a coil spring typically requires removing the shock from the bike and backing off the preload collar to release tension. While you don't need specialized tools, you should have a basic understanding of your shock's service manual to ensure the spring is seated correctly.

This spring is engineered specifically for RockShox metric shocks. While some springs may physically fit other brands, we recommend sticking to the manufacturer's specified components to ensure the spring diameter and fitment are correct for your specific shock body.
