Rear main seal Issues *PICS*
So I'm replacing the main seal in my 5.3 pull out cause I accidently tore it when installing the rear cover plate. The motor is somewhere between a 00-03 and I'm having troubles finding a seal that matches the stock seal.
Gm on the left and Federal Mogul/National on the right
Gm left and Napa SKF on the right
Has anyone else replaced a rear main seal on a GENIII Ls engine and had this issue or is it just me? the Federal Mogul seal number was cross referenced with the stock seal and the guy at O'reillys gave me it. I was leary do to the fact its no where near close to the same width as the stock seal, so I went to Napa and they gave me the SKF seal and its the closest width to the stock seal but the material and construction of it greatly differs and that kinda worries me. I don't wanna pull the motor after installing it cause of this.

When I replaced my old rear main a few months ago I ran into the same thing. The new OEM GM seal was about half the thickness of my old one. I asked the guys at the dealership about it and its just an updated version. Haven't had any issues so far with it.

Hmmm well I think I'm gonna use the federal mogul brand, it slides right in and the design is very similar to the stock one. I have a feeling the napa one requires a special tool to install because it is practically hollow besides the actual seal that sits around the crank, and there is no way to get it in without pressing it.

I'd go with the Federal Mogul myself...they produce the factory bearings, so I wouldn't doubt that the make the factory seals also
