xr4 - piston rings - darker or brighter on top

Recommended Posts

Hi all

I'm rebuilding my XR4. The "N" on the piston rings should face up, but does the darker or the brighter (more "silver-y") ring go on top?

I can not see any chamfer on either ring, even with a magnifying glass.

The shine on the face of the ring is the moly in the ductile iron on most rings- aka top/1st ring

Second Compression ring is usually just plain cast iron/dark face ring.
