These SLS (Super Light Steel) springs are a lighter weight steel spring option offered in addition to Fox standard steel springs.

The new SLS springs are lighter than titanium springs at more affordable prices. A proprietary surface treatment and stress relief process removes residual stresses from the spring, allowing them to withstand higher stresses. Each spring is optimized by using a smaller wire diameter and fewer coils, creating a lighter spring.
