SLS (Super Light Steel) springs are now available from FOX for DHX and VAN rear shocks. These SLS springs are a lighter weight steel spring option offered in addition to our standard steel springs. The new SLS springs from FOX 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.

 

  • For 2019 FOX has developed a new line of SLS springs to optimize performance on all coil shock platforms including the newer metric and trunnion options. All 2019 SLS springs are Orange and are marked with their spring rate in lbs/in and the total travel of the spring itself in both standard and metric. 2019 SLS springs should only be paired with shocks having less travel than the travel marked on the spring itself.

*NOTE: Spring TLG (Total Length) listed is an average of a sample of springs. Your springs TLG may vary beyond the dimensions listed above.

WARNING: Tighten the preload adjuster just until the spring no longer moves, then preload no more than 2 full turns. Preloading the spring more than 2 full turns may cause the spring to coil bind when the shock is bottomed out. This can cause damage to the shock which could lead to a loss of control resulting in SERIOUS INJURY OR DEATH.
