Norton Rocker Spindle
A rocker spindle from the valve gear, the shaft a rocker arm pivots on to open and close a valve.
NM25350 is a rocker spindle, the shaft that a rocker arm pivots on up in the cylinder head as part of the valve gear. The rocker rides on the spindle and rocks back and forth to open and close a valve each time the cam pushes on it, so the spindle has to hold its position solidly and let the rocker swing freely without slop.

Our catalog record for this one is thin - it shows up once, tied to a valve gear listing from 1973. We don't have enough in our records to tell you which specific engine or head this spindle was speced for beyond that.
If you're rebuilding a head and need to know whether this is the right spindle for what you've got apart on the bench, call the shop and we'll go over it with you before you order.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
