RING SET 850 .020 GRANT
Grant .020 oversize ring set for the Norton Commando 850 engine.
This is a Grant piston ring set for the Norton Commando 850 engine, ground to the .020 oversize. It's a set sized for a rebore, not a standard-bore replacement set, so it only makes sense once the cylinders have actually been taken out to that dimension.

The catalog record we have on this one is brief, and it doesn't come up often in our books, so beyond confirming it's an 850 Commando ring set at the .020 over size, we don't have more detail on file. If you're working from a different reference number, ours also shows this part under 23177.
Give us a call before you order to confirm it matches your bore spec and the rest of your rebuild parts list.
