Product Information

Full details

The RFX Exhaust Springs (57mm) are essential components designed for motocross and enduro riders who require a reliable, high-tension connection for their exhaust systems. These springs offer excellent heat resistance and durability to prevent exhaust leaks and vibration-induced rattling, though they are specifically sized at 57mm and must be verified against your bike’s specific mounting points before purchase to ensure proper fitment.

FAQs

Are these springs sold individually?

No, RFX Exhaust Springs are supplied as a pair to ensure you have consistent tension across the exhaust mounting points.

How do I measure for the correct spring length?

Measure the distance between the center of the two mounting loops on your exhaust system when the pipe is fully seated.

Can I use these on any exhaust brand?

Yes, as long as your exhaust system requires a 57mm spring, these are compatible with most standard off-road exhaust configurations.

Do I need a special tool to install these?

While it is possible to use pliers, using a proper exhaust spring puller tool is highly recommended to prevent injury and avoid damaging the spring.

How often should I replace these springs?

Replace them whenever you remove the exhaust pipe, or if you notice they have lost their tension, appear stretched, or show signs of heavy corrosion.

Troubleshooting

Spring is difficult to stretch into place

Use a T-handle spring puller tool to gain better leverage and ensure the spring is correctly aligned with the mounting loop.

Exhaust still rattles after installing new springs

Check the mounting loops on your exhaust for excessive wear; if the loops are elongated, even a new spring may not provide sufficient tension.

Pros and Cons

Pros

  • Durable steel construction resists premature fatigue
  • Sold in pairs for balanced installation
  • Standardized sizing ensures reliable fit on compatible systems
  • Effectively eliminates exhaust leaks caused by loose fittings

Cons

  • Length is fixed at 57mm; incompatible with systems requiring different tension specs
  • Requires proper spring puller tool for safe installation
  • Standard finish may require occasional cleaning to prevent surface oxidation

Setup, Compatibility & Care

To install, use a dedicated exhaust spring puller tool to hook one end onto the exhaust pipe lug and the other onto the cylinder or frame mount. Ensure the springs are not over-stretched during installation, as this can weaken their tension. These springs are compatible with a wide range of two-stroke and four-stroke exhaust systems that utilize 57mm mounting points. To maintain their integrity, keep the area free of excess mud and grit, which can act as an abrasive. If the springs appear oxidized or loose, replace them immediately to avoid exhaust leaks that can affect engine performance.
