Specifications

Enhance your mountain biking performance with the Fox Shox SLS Spring - a high-performance, lightweight coil spring engineered for optimal shock absorber compatibility and durability. Crafted from proprietary Fox super light steel (SLS), this spring offers unmatched strength-to-weight ratio, making it an ideal upgrade for serious riders seeking agility and responsiveness on rugged trails.

Materials & Engineering Excellence

Constructed from advanced lightweight steel, the Fox SLS Spring features a proprietary surface treatment and stress relief process that reduces wire diameter while maintaining exceptional strength. This innovative manufacturing process results in a lighter spring that doesn't compromise durability or performance, enabling smoother rides over challenging terrains. The black finish adds a sleek aesthetic, complemented by the spring's robust build quality designed to withstand the demands of aggressive riding.

Component Compatibility & Performance

Designed with a 1.385-inch (35mm) inside diameter, the Fox SLS Spring guarantees a perfect fit for Fox coil shocks, as well as compatible models from Marzocchi, DVO, MRP, and X-Fusion. With a spring rate of 400 lbs and a stroke length of 74mm (2.9 inches), it delivers precise damping and support tailored to aggressive trail riding, enduro, and downhill disciplines. Whether you're upgrading your existing shock or customizing your suspension setup, this spring ensures optimal performance and improved shock responsiveness.

Innovative Features & Usage Scenarios

The Fox SLS Spring's unique stress relief and surface treatment process make it stand out among standard steel springs, providing enhanced fatigue life and consistent ride quality over time. Its lightweight design reduces overall bike weight, boosting climbing efficiency and handling-critical for demanding rides. This spring is ideal for riders looking to optimize their suspension system for better control, increased weight savings, and reliable performance in challenging environments.

Fitment & Technical Support

For accurate fitment, refer to Fox's comprehensive spring help guide [here](https://tech.ridefox.com/bike/general-info/918/all-sls-and-standard-steel-rear-shock-spring-information). The 35mm/1.385" S.H.I.S. stem clamp diameter ensures compatibility with various shock models, making installation straightforward and secure.
