Bring Back Predictable Slipper Action to Your Kyosho 2RSA with OL027

The Kyosho OL027 slipper spring is intended as a direct replacement for worn springs in the 2RSA truck series, restoring consistent slip characteristics and reducing shock to the gearbox under heavy load.

Engineered for Stable Adjustment

Providing a steady spring rate, the OL027 lets you fine tune the slipper clutch without surprise shifts in engagement. This reliability is useful when you are balancing traction and drivetrain protection.

Fits Kyosho 2RSA Slipper Assemblies

Manufactured to fit the slipper assembly used across the 2RSA trucks, the OL027 installs simply and is a practical part to carry for trackside maintenance.
Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Can I change slipper behaviour by combining the OL027 with a different clutch shoe?

Yes, pairing the OL027 with shoes of different friction material can alter slip characteristics. Test combinations gradually and monitor clutch temperature during tuning.

Will the spring handle high-power brushless setups?

The OL027 is designed for 2RSA use and can help protect the drivetrain, but very high power motors may require additional clutch or gearing changes to avoid excess wear.

Any tips for trackside troubleshooting after installation?

Carry a spare spring and basic tools, check for consistent slip after a few runs, and listen for unusual gear noise. Re-check preload after heat cycles to keep performance steady.

How do I know when the spring needs replacing again?

Replace the spring if you observe reduced tension, uneven engagement, or visible deformation. Regular inspection during servicing helps avoid sudden failures.
