## Description

FelPro gaskets offer 100% vehicle sealing with applicationspecific materials to give you sealing solutions with the performance and durability professionals trust

Review: Great choice for rear main gasket/seal replacement - I chose this over a lot of other cheap, generic aftermarket rear main seals and gaskets. It's also mainly the rear main seal that's the most important, aside from the rear main cover gasket. I've seen a lot of the really cheap aftermarket rear main seals leak, so I wasn't going to take a chance; especially not after dropping my whole transmission and really not wanting to have to do that again in the next 10-20k miles (or maybe even less!). I did have a separate OEM GM LS rear main seal that I used, but this Fel-pro one is just as good, in my personal opinion. The cheap ones are sometimes a bit smaller in size, and the rubber material isn't as durable, which causes leaks as it gets heat-cycled. I also bought a billet aluminum rear main cover alignment tool, to center the rear main cover for installation (along with the new cover gasket), before using it to install the new rear main seal cover. I guess it's more exact to install using the alignment tool, but I've done it in the past with the rear main seal installed BEFORE re-installing the rear main cover, and I was still fine. Lastly, you'll also want to make sure to clean all the surfaces to the mating surfaces, including the oil pan gasket portion that the rear main cover sits on. I personally used Permatex ultra black RTV gasket maker, which is oil safe. The ultra gray version works as well, but I'm sure any high temp and oil-resistant RTV gasket maker, should do the trick just fine.
Review: Perfect fit for a 5.3L engine on our 2005 Yukon, would buy again. - Worked perfectly on our 2005 Yukon. The old rear oil seal was shot after 300K miles, oil was just poring out. Once the plate was pulled the old seal just fell out. This seal and gasket fit perfectly. No more leaks!
