Product Information

Full details

The RFX Exhaust Springs (57mm, Swivel) are essential components designed for motocross and enduro riders who require secure and vibration-resistant exhaust mounting. Engineered with high-quality materials, these springs provide a reliable connection that withstands intense thermal expansion and engine vibrations. While these springs offer excellent durability, users must ensure they measure their existing springs accurately, as the 57mm length is critical for maintaining the correct tension on specific exhaust systems.

FAQs

How do I measure my exhaust spring correctly?

Measure from the inside of one hook to the inside of the other while the spring is in a relaxed, uninstalled state.

Are these springs compatible with all motorcycle brands?

These are universal-style springs but must match the 57mm length requirement of your specific exhaust system.

Does the swivel feature make the spring weaker?

No, the swivel feature is designed to reduce mechanical stress on the hook, actually increasing the lifespan compared to fixed-end springs.

Should I replace both springs at the same time?

Yes, it is highly recommended to replace springs in pairs to ensure even tension and prevent exhaust leaks.

Can I use these on a four-stroke exhaust?

Yes, as long as the 57mm measurement matches the mounting requirements of your specific four-stroke exhaust system.

Troubleshooting

Spring is too short to reach the mounting hooks

Verify that your exhaust system requires 57mm springs; do not overstretch the spring as this will lead to immediate failure.

Swivel end is stiff or stuck

Apply a small amount of heat-resistant penetrating oil to the swivel joint to loosen it before installation.

Spring vibrates excessively during idle

Ensure the exhaust pipe is properly aligned with the cylinder port; a misaligned pipe can cause unequal tension on the springs.

Pros and Cons

Pros

  • Swivel ends reduce tension stress and prevent snapping
  • High heat resistance suitable for racing conditions
  • Durable build quality for long-term reliability
  • Includes a pair of springs in each package

Cons

  • Strict length requirement limits universal application
  • Requires proper tools for installation to avoid injury
  • May be difficult to install on very tight exhaust manifolds

Setup, Compatibility & Care

To install these springs, it is recommended to use a dedicated exhaust spring puller tool to prevent accidental slipping or finger injury. Ensure the exhaust manifold and pipe hooks are free of heavy carbon buildup or debris, as this can affect the seating position. When installing, ensure the swivel end is facing the side with the most movement. To prolong the life of the springs, periodically clean them with a degreaser and check for signs of stretching or oxidation. If the spring appears to have lost its tension or has visible cracks, replace the pair immediately to ensure the exhaust system remains properly secured.
