I believe the 603 requires replacement at 4 degrees...

A 617 chain and most double row chains for that matter can't be beat, the 603 chain may not be quite as durable, but the jury is still out on that until enough high mileage owners chime in.

My 603 chain has 215K miles and just under 0.5 degree stretch If the same wear pattern is maintained, I should get close to 2 million miles before replacement is indicated. I doubt that the rest, nor I will hold up though.

Change that oil hot and often! (not to steal a quote from notable others)
