Bought this cover for my 2016 Chevy 3500 dually. Easy to install, holds 2 gallons of fluid! Was able to use all the stock brackets with a little fabricating. Definitely recommend this product!

Questions and Answers

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

Where can I buy a replacement dipstick for this cover?
