I changed mind a month ago to FP one, it took 3.5 quarts of Amsoil, i used Lube locker. They say to use the original bolts. Not the one that comes with the Diff cover. I decided to upgrade the bolts with this: ARP Differential Cover Bolt 437-3002; 12pt Stainless for GM 8.875 in. 12-Bolt. Solid bolts!!! Highly recomend the bolts.
The FP one is supposed to come with new gasket and new bolts? My 2 did.
yes it does. but from what i hear from others who used the gasket and bolts. they highly recomend not using it. the gasket that comes with the Diff Cover is paper thin, and people were having problems breaking the bolts. they were recomending to use the original one.
What gasket you use? Curious.
So on my first 2 covers (2017 and 2020), I used the gasket and bolts that came with the cover....no problems. However, I decided to try the Lubelocker gasket after taking a look at how it was made. Looks way better than the one that came with the cover. Also got the ARP Differential Cover Bolt in SS. On the 2017 I just slapped it on and the FP label looked that crap after couple of years. For the one on the 2020, I coated it and it held up better. Posted this pic somewhere and it is 4+ years old in this pic.
