## Description

GM Housing - 12639250

Review: Only way to go ...buy Genuine
Review: 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.
