The cover is beautiful and well made. Very,Very expensive. I had to paint it because Black is not the color I wanted for this application. The gasket that was received is crap. I used it for a blueprint to copy onto real gasket material. Looks excellent on my 2006 Hummer H2.

I was having problems finding a better rear differential cover for my H2 SUT. The problem was clearance to the sway bar.This cover fits PERFECTLY and looks awesome!!!
