SLS Coil Spring

What Our Gearhead® Experts Are Saying:

"I spec'd the SLS Coil Spring to match my riding weight, and the difference over the standard steel spring was immediately noticeable on the trail. The SLS material gives you a lighter, more responsive feel without the titanium price tag, and FOX's wide range of spring rate options means you can actually dial in the right setup for your body and your bike rather than settling for close enough."

Getting a coil shock dialed is one of the most rewarding things you can do for your mountain bike, and the spring is where that process starts. FOX's SLS Coil Spring is made from Super Light Steel, a proprietary surface-treated and stress-relieved material that comes in lighter than titanium at a more accessible price point. The stress relief process removes residual stresses from the spring, allowing it to handle higher loads with a smaller wire diameter and fewer coils than a standard steel spring, which means less unsprung weight moving around under your bike and more of the trail feedback you actually want to feel.

Available across a wide range of spring rates to match your riding weight and style, the SLS Coil Spring fits FOX DHX and DHX2 rear shocks as well as DVO, MRP, and X-Fusion shocks with its 35mm internal diameter. Getting the right spring rate is everything with a coil setup, and FOX's spring calculator takes the guesswork out of the selection process. Once you're on the right spring, the difference is the kind that makes riders wonder why they waited so long.
