Performance or stock seals great
I used the one that came with a seal kit and it didn’t last a week ordered this one and had a lot thicker material and way better quality. I run it on my supercharged, cammed out and many more awesome upgrades and it hasn’t leaked one bit and I beat on it pretty hard

So far so good. Inexpensive oil leak fix.
If changing your harmonic balancer on your c5 corvette you need this $20 part in the event your old one is bad or starts to go bad. This is right under the balancer and just snaps in. Do yourself a favor and buy one when replacing your balancer and save yourself having to take it apart again when it starts to leak oil.

Sizes given are incorrect but it fits the LS engine applications.
Item dimensions L x W x H 3.4 x 3.4 x 0.4 inches The OD of the seal is 2.83465 or 53.5mm. 53.5mm X 72mm X 6 mm. Mine fit just fine, only the description is incorrect.

Easy to install. Worth paying a bit more to have the OEM piece of mind.

Bought this seal to replace another brand seal that leaked from the date of install, installed this ac delco seal and no more leaks!
