70-9779 is a rocker arm for the triumph triple's cylinder head, listed for the inlet valve on the T.S. side and the centre exhaust valve position. It sits inside the rocker box, riding on its shaft and transmitting motion from the pushrod down to the valve stem each time the cam lobe comes around.

The legacy number for this one is E9779, which is the older factory reference you may find in earlier parts books. It shows up in our records under the CYLINDER HEAD AND ROCKER BOXES figure, which is where you'd expect a rocker arm to live.
Our catalog data covers this part in 1969 listings. If you're sorting through a triple's top end and matching up rocker arms by position, have the head off and the old arm in hand so you can confirm you're ordering the right one for that specific valve location.
