      Good

      This is your typical paper diff gasket cover. It's nothing special, but works to fix any leaks you have from your rear diff. It fit perfectly and lined up with all of the bolt holes. For the cheap price I definitely recommend getting this.

      Necessary and cheap but you gotta buy multiple

      I was aware this was only a package of one (1) but I just wish they could take the guesswork out and sell the correct amount of bolts needed for a camaro differential cover I still will rate this product a 5/5 because ive had no issues

      Fantastic

      Mechanic was able to install this fully and quickly. Had all the parts I needed to freshen the bearing and seals up. My 8.8 is now smooth and dead quiet.

      Bearings & seals

      My review may not mean alot. passenger side axle should have been addressed long ago. I had to build the axle back up from groves caused by smoked bearings. I may not have built enough or too much where the seal sits because it started leaking after a week of service. Bearing is still good but need to replace seal again.
