Item as described and fit perfect. No leaks
Only critique I have is that I wish the purchase would've came with the bolts as well.
Like the original
The magnet was so weak, it could not be installed for fear of it dropping off and being loose in the differential.
Excellent quality
I recommend the rear differential cover. It fit perfectly and the access hole in it made it easy to refill the differential.
very good fit..looks good too.
Looks good and just freshing up parts
The parts I purchased through A1 Auto where exact fit ! Also the video was extremely helpful ! Thanks A1 Auto ??
I purchased a rear differential cover and it fit perfect I didnt have any problems. I also bought several parts for my truck from 1A auto and they were also good parts

Yes, it is included.
Thank you for your inquiry! The magnet that comes with this cover should already attached to the cover, but if it is detached you can usually use some strong adhesive that will be able to stand up to higher temps. If the part was ordered from us please contact our customer service department for further assistance.
