RockShox Vivid / Kage Coil Spring

No, this specific spring is designed exclusively for RockShox Vivid and Kage rear shocks. It features a 38mm inner diameter, so you must verify that your shock model and stroke length match these specifications before purchasing.

Spring rate selection is highly personal and depends on your rider weight, bike leverage ratio, and preferred sag. A 400lb spring is typically suited for lighter riders or bikes with specific suspension kinematics, so we recommend using a spring rate calculator based on your exact bike model and total riding weight.

The 3.5-inch measurement refers to the maximum stroke length the spring can accommodate. Ensure your shock's stroke is equal to or less than 3.5 inches; using a spring on a shock with a longer stroke than the spring is designed for can cause coil bind and damage your equipment.

While this specific model is constructed from durable aluminum, the primary advantage is weight savings compared to traditional steel coils. It provides the consistent, linear feel of a coil setup without adding as much mass to your bike's rear end.

It is generally not recommended. The 38mm inner diameter is specific to RockShox Vivid and Kage shocks, and other brands often use different diameters or collar interfaces that will not seat correctly, creating a safety hazard.
