cover looks real good and is pretty functional. I drove around with it for 15000 miles then had to pull the cover off because I blew up my R&P from doing boosted launches with my 35s at the track. After all that time the oring was still good. nice product

On my 2010 Dually, perfect fit, having a dipstick is great. Adding a diff sensor for temp. Amsoil severe gear oil runs great and dont stink like normal gear oil, a simple but happy + for me. You wont be dissapointed when you compare this to the stock one, well worth it!

Total capacity 8 quarts, what is the actual gain over stock cover?
View Staff Answer 
Answer

Your stock 11.5 differential takes about 4.5 qt’s. This Mag-Hytec AA 14-11.5 differential cover will take approximately 6 qt’s. to fill the bottom of axle tube (lower line on dipstick) and 7.5 - 8 qt’s. to the bottom of axle (top line on dipstick) . YOUR OIL LEVEL SHOULD BE BETWEEN THESE LINES
