Fox Shox SLS Coil Rear Shock Spring The SLS (Super Lightweight Steel) spring enables you to achieve optimum suspension performance, with a lightweight spring that doesn't cost the earth! The Fox SLS Spring uses a proprietary surface treatment and stress relief process to remove residual stresses from the spring, so they can withstand higher stresses. It uses a smaller diameter and fewer coils to create a lighter spring. This version has a 3.00" maximum stroke, and is offered in weights with measurements in pounds. Please note: Stroke is dependent on your current shock and rate is based on your rider weight. To determine the correct spring rate please visit the Fox spring rate calculator page at the link below. https://www.ridefox.com/fox_tech_center/owners_manuals/08/WCeng/Content/mtbspringratecalculator.html
