S&S Cycle 70-99 BT .340in x .420in x 1.375in Crankcase Oil Screen Spring

This is the S&S Cycle crankcase oil screen spring, part number 31-2011-S. It's a small but important piece that works within your engine's oiling system to help filter out debris before it circulates. Think of it as a gatekeeper for your oil, ensuring that only clean oil makes its way to critical engine components.

While it might seem like a minor part, a properly functioning oil screen spring is key to maintaining the health of your engine over time. It works in conjunction with the oil screen to catch larger particles that could otherwise cause wear and tear. This particular spring from S&S Cycle is well-built and designed to fit correctly in its intended application, helping to ensure your oil stays as clean as possible.
