I'm prety sure it does (I didn't assembly my kit). Is the support ring thicker/heavier than the ring you would be replacing? if so, you're probably on track. I'd give the kit supplier a call to double check Maybe they sent you the wrong oiling ring kit.I have the 2 rings on the piston with the oil ring in between and the oil rail support ring is supposed to go on the bottom of those 3 rings but there isn't any room for it. Does it take the place of the lower ring?
