Rear main seals?

[ah1988ford]

I just bought a felpro rear oil seal and it is different from stock I just wanted to know which seal is better they are 2 different kinds the old one has a spring in it to keep tension and its made out of rubber and the new one is just like a plastic flexible ring it kinda scares me to use it seems like it would wear out premature

I would use the rubber and spring one.

The plastic ring is for the install only. After that, you pull it out and throw it away. Either type will work just fine, even it it's different than stock.

It sounds to me like you purchased the new style seal.It has a steel wear ring and the actual seal has two lips. Please read the install directions when installing it.

if you installed or are going to install the fel-pro speedi-sleeve on the crank, you can only use the rubber seal with spring ONLY.
the new design seal does not have enough "give" to accomodate the installed speedi-sleeve.

The one i put in my truck was a different material that required to be installed dry.

That's the newer style.
