Who says you have to order a ring "set". You buy what you NEED. Pick up the phone, call and order (x) top ring, (x) second ring and (x) oil ring. Just because a prepackaged "set" doesn't come with what you need, doesn't mean the rings are not made.I couldn't find hellfires anywhere on a 1/16 1/16 3.0mm package so I ended up getting JE moly rings. On average I refresh/tear down at least every other year or as needed. Are the hellfires available with a 3.0mm oil ring or is it something that can be special ordered? Thanks.
I decided to go with a hellfire top ring on my 496 nitrous engine.IIRC, the "Hellfire" ring was originally a material that was designed for the abuse a diesel can dish out. IE extremely high combustion pressures. This makes it a natural for nitrous use. It is NOT a tool steel material, nor stainless and as such I have never seen, nor should it have excessive bore wear in something that will be together for a long time. Honing procedures are nothing special and they seat QUICK. Just a very good all around ring
Once again guys, forget buying fixed "sets" of rings. Total Seal most certainly makes a .043 Hellfire for a 4.530 bore. They also make ANY second ring you want and they make ANY oil ring you want, just maybe not in a pre-packaged "set". So you call them on the phone and say I want this, this and this. I NEVER buy sets of rings. I buy what I want and make my own set.How about the JE Pro seal? We could not find the Hell fire in an .043 1/16 3/16, 4.530 bore but was told the JE Pro seal would be as good and they had the rings in stock. I sure hope they are. The price sure reflects a good ring.
