Fox Suspension SLS Spring

The SLS (Super Light Steel) spring uses a proprietary alloy that allows for a thinner wire diameter and fewer coils. This significantly reduces weight, bringing it much closer to the performance and feel of a titanium spring without the high cost.

The SLS spring features a 1.385-inch inner diameter, which is a common standard. While it is designed for Fox shocks, it is generally compatible with many other brands, provided the inner diameter and stroke length match your specific shock's requirements.

The stroke length refers to the maximum amount of travel the spring can safely compress. You must ensure your shock's stroke is equal to or less than 2.9 inches; using a spring with a shorter stroke than your shock can cause the spring to bind and damage the system.

No, the spring rate is fixed at 550 lbs. If you find your suspension is bottoming out too easily or feels too harsh, you will need to swap to a different spring rate rather than adjusting the current one.

Yes, the orange finish is part of an advanced surface treatment process. This treatment is essential for the spring's durability, helping to prevent corrosion and fatigue over time.
