VALVE SPRING SET NORTON 750/850 - KWPM (SPRINGS, CUPS, COLLARS)
Complete valve spring set (springs, cups, collars) for Norton Commando 750/850 twins.
This is a valve spring set for the Norton Commando 750/850 twins, packaged as a complete kit with springs, cups, and collars included. It's a Norton part, not a Triumph one, so if you're working on anything with the JRC part number here it's meant for the Commando engine family, not the unit or pre-unit Triumph line.

The set covers what you need to redo the valve gear on both valves per cylinder - the springs that close the valves, plus the cups and collars that retain them on the valve stem. Because it's sold as a set, you get matched components rather than piecing together springs and hardware from different sources.
We don't have a lot of history on this one in our own records, so if you've got questions on exact application within the 750/850 range, give us a call and we'll sort out fitment before you order.
