Did the job
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.

Well worth it
The new hardware was a pleasant surprise. Much better than crappy felpro no need to mess with pressing a new rear main seal in. Great price for a clean new cover, both seals AND hardware
