Description
Exhaust spring degradation is one of the most overlooked causes of poor exhaust sealing and performance loss in 4-stroke engines. The FMF Stainless Spring Kit replaces worn or fatigued OEM springs with premium stainless steel components that maintain consistent tension and clamp load, ensuring your exhaust system stays sealed under vibration and thermal cycling. This direct bolt-on replacement restores proper exhaust manifold sealing, reduces exhaust leaks, and prevents the rattling or movement that can compromise both power delivery and engine longevity.
