We have had electric fleets for the last few leases but I believe the rings go taper "up"

I'll try to run down the ezgo factory guy and see what the service manual says but that might be Monday.

Can you post the manufactured year and/or a unit serial number?

Taper up! this channels the gasses down to the backside of the ring (direct charging) forcing the ring outward - seal is bottom of ring to top of land and face of ring to cyl wall. THIS MATCHES THE PISTON RING GROOVES!!!

 

And NO they won't fit ether way - upside down will bind big time. If NOT grooved for HK you should not run HK!
