RockShox Service Part AM Coil Spring Isolator Kit

The RockShox Coil Spring Isolator Kit is designed to reduce unwanted noise and vibration inside your fork. It’s a simple yet effective upgrade that improves ride quality by eliminating spring chatter in coil suspension systems.

Tailored for All RockShox Coil Forks: Compatible with all RockShox coil spring forks, the isolator sleeves slide easily over the coil and are secured using heat shrink. Once installed, they form a snug barrier between the spring and stanchion tube for quieter, smoother operation.

Durable Heat-Shrink Material: Each isolator is made from high-quality heat-shrink tubing that conforms tightly to the coil spring when heated. This ensures lasting protection and a precise fit that won’t shift or degrade under pressure or vibration.

Reduces Rattle and Internal Friction: By creating separation between the coil and fork internals, the isolators help reduce metallic contact and internal friction. The result is a cleaner, more controlled feel through the entire stroke—especially appreciated on rough terrain.

The kit includes three heat-shrink coil tubes, giving you everything needed for a full fork install. It’s a low-cost upgrade that brings noticeable improvements to both noise reduction and ride smoothness.
