Rear Main seal question.....rubber or Teflon

  1. Autozone sells two Felpro rear main seals. One is rubber and is $10 and the other is Teflon and is $20 and special order

    If the Teflon one better to get? I want to do this once and not have it leak anytime soon.
  2. If you have a stick car and you drive it, don't plan on putting in a rear main seal once and forgetting about it- they go through them like dirty socks. The teflon one is better. I don't know that it's ten dollars better, but WTF? It's only $10! You can look at it two ways: either, "Oh my God! It's 100% more expensive!"; or, "after spending $450 on this clutch job, what's another ten bucks?" Your call- I splurged and got the one that sounded cool.
  3. LOL i just got my rear main seal done with my 450 clutch job on friday.

    I say get the teflon.
  4. The teflon will take the heat better and not be prone to cracking like the rubber does.

    If properly installed they will last for a long time....
