Genuine GM replacement part. Fit perfectly and made repairing the rear engine cover leak a simple process. GM has several EXPENSIVE specialty tools to install the front and rear covers, and oil pan on the LS style engine. I have never used them, and have not had any problems. With the main seal preinstalled, the OE tools would not work anyway. Additionally, the rear main seal can center itself over the rear crank snout, unlike the front cover where it actually seals against the damper pulley, not the crank. The OE method, installs the rear cover without the seal, then installs the seal, so positioning of the cover prior to the seal would be critical.
Bolts originally were a 10mm head, revised bolts were a 13mm head.
Installation: I applied a small bead of RTV to the joint of the oil pan gasket and the rear of the block on the left and right sides. I positioned the cover with the seal protector still fitted, as the bolts are retained by the cover seal. I worked my way around and started all of the cover bolts and allowed the cover to loosely fit over the crank snout, pushing the seal protector from inside of the seal. Once the cover bolts were finger snug to the back of the engine, I installed the two long oil pan bolts and torqued them to 106 in-lbs. The cover bolts are then torqued to 18 ft lbs. Before doing that, I snugged them all with a socket then loosened the long oil pan bolts to ensure the cover was pulled into place. Then retorqued the oil pan bolts, and then the rear cover bolts in a criss cross pattern.

I bought this for my 2007 Tahoe LT Flex Fuel 5.3L truck. I was leaking oil from underneath and figured the truck has over 170k on it so instead of just replacing the seal itself, I decided to get this done plus a bunch of other seals (oil pan gasket, pick up tube o-ring, etc). Had my buddyβs shop take care of the physical work but buying my own parts and comparing prices elsewhere, Amazon had everywhere best by a lot. If your mechanically inclined then save on labor and do it all yourself but this is intensive and for me Iβm an avid DIYer but this, I had to pass it up.
Good luck, hopefully this will resolve any leaks youβre having between your block and tranny. Itβs updated design comes with everything you need for the 1 for 1 install. My truck has almost 1000 miles with this installed no further issues coming from the block.

This kit fixed my rear main seal leak on my Silverado. My stepdad ordered the same set and we fixed his Cadillac Escalade as well. The upgraded bolts are nice. Some reviews say it is not genuine OEM. I really don’t know if it is or isn’t. I’m not sure how you can tell but it definitely fits correctly and does the job. It is also easier to do with this kit than swapping the seal without a new housing.
