RING SET 63MM+.030 NOS
NOS piston ring set for a 63mm bore at +.030 oversize.
This is a piston ring set, sized for a 63mm bore at +.030 oversize, listed in our records as NOS (new old stock). Ring sets like this go on the piston to seal the cylinder and control oil, and the +.030 marking means it's ground for a cylinder that's been bored out that extra amount over standard, likely during a rebuild.

The manufacturer tag on this one says Amal, but Amal is a carburetor maker and has nothing to do with piston rings, so that tag is not something to go by. Our entry on this part is brief and we don't have more detail on it beyond the ring set description and bore size.
If you're working on a rebuild and need a 63mm +.030 ring set, give us a call and we'll confirm what engine and application this particular set was cataloged for before you order.
