FEL-PRO BS 40640 Engine Crankshaft Seal Kit for Chevrolet Silverado 1500

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.

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!

Fit like a glove and the oil no longer leaks Half the price as the autoparts stores

Worked perfect on my 01 Chevy Tahoe 5.3.

Oem parts for a fraction of the cost! Perfect fit and shipping was fast

Great gasket set. Be sure to get the cover alignment tool! Made the job a breeze and had zero leaks.

Obviously its as easy to put in as the other 1 was to get out. It was a better price then I could find going to the local parts store. The fit has been just as it should be and has sealed great.

Can’t go wrong here, fit good and no leaks. Also I didn’t use an alignment tool. If you inspect the seal all around the crank and make sure the spacing is even you’ll be fine. Takes a close eye and flashlight to see it. Use the oil pan bolts to adjust up and down and torque those last.

Has been a quality product for many many years (50 years in my case), so you can not go wrong with Fel-Pro.

Excelente producto

Required it for a l92 rebuild

I have been using fel-pro for many years and hold up very well on seal oil on engine. Product very similar to oem style and design.

Perfect fit, fast shipping
