SLS (Super Light Steel) springs are now available from FOX for the DHX and VAN rear shocks. These SLS springs are a lighter steel spring option offered in addition to our standard steel springs. FOX's 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 using a smaller wire diameter and fewer coils, creating a lighter spring.
All SLS springs are orange and are marked with their spring rate in lb/in (in 25 lb increments) and the maximum travel of the shock they are designed to pair with.
