This is a BSA part, not a Triumph one, so if you're working on a B40 rebuild and your bore has already been taken out to the +.020 size, this is the kit that matches. Our records on this one are brief beyond the basic description, so if you need to confirm what's included in the kit (rings, pin, clips, etc.) give us a call before you order.
We don't have much more detail on file for this part number. Best to check with the shop on specifics before you commit to the +.020 size for your rebuild.
