Helix Swift Coil Spring 55mm

The Helix Coil Spring 55mm is a rear shock spring developed in partnership with Swift Springs, a manufacturer of coil springs for high performance applications. The spring is built from a proprietary alloy that resists deformation under repeated heavy loading, maintaining consistent rebound speed and performance over extended use.

Each spring is held to 2% spring rate accuracy, reducing one variable when dialing in a suspension setup. Spring rates are available in 25lb increments across the full range, allowing riders to fine-tune preload and support to match their weight, riding style, and terrain conditions.
