Frequently Asked Questions
Q: What is the primary purpose of the NAS Big Brown Spring?
A: This spring is designed to increase your clutch engagement RPM to the 3850-4900 range. It is ideal for racers who need a higher stall speed to keep the engine in its power band during corner exits, preventing premature clutch slip.
Q: Is this spring compatible with all Nor-Am clutches?
A: The NAS Big Brown Spring is specifically engineered for the Nor-Am GE Series clutch. Please ensure your clutch model is compatible before installation to ensure proper performance and safety.
Q: How do I know if I need to switch to this spring?
A: If you notice your kart feels sluggish off the corners or your current clutch engages too early for your engine's power curve, upgrading to a higher RPM spring like the Big Brown can help you achieve a more aggressive and responsive launch.
Q: Does the color-coding indicate anything other than the RPM range?
A: Yes, the brown color-coding is a standard Nor-Am identifier that allows mechanics and drivers to quickly verify the spring rate during trackside maintenance without needing to measure the tension manually.
Q: Should I replace all springs at once?
A: For consistent clutch engagement and even wear across the shoes, it is highly recommended to replace all springs in your clutch assembly simultaneously rather than mixing different spring rates.
