Fox SLS Super Light Steel Rear Shocks Coil 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 less coils to create a lightwer spring.
