The Kyosho OL027 slipper spring is a straightforward replacement part for the 2RSA truck series that helps stabilise power transfer during launches and hard acceleration. It protects gears by allowing controlled slip under excessive load.
With a stable spring characteristic, the OL027 supports repeatable slipper clutch settings so you can tune for traction or top-end efficiency. That makes it practical for both casual running and competitive heats.
Built to match the 2RSA slipper assembly layout, the OL027 installs without modification and is a direct way to refresh an ageing clutch system.
