2017 and newer Nissan Titan trucks with a 12 bolt differential.

The ring gear is probably 9.5 or 9.75 inches and probably made by American Axle for Nissan trucks and SUVs.

This PML cover is based on Nissan stock cover 38350 EZ20A. Nissan gasket is part number 38320 EZ20A.

Some 2016 and newer trucks have a 14 bolt rear differential cover. See PML Part Number 11157.

Always check your vehicle to verify differential and space available for a larger cover. Because configurations vary, PML cannot guarantee fitment.

2021 Nissan Titan

Brian installed this PML cover on his 2021 Titan. He reported that the installation went well and he was happy. We love the custom blue color he used.

Brian found that he needed to loosen the clip on the cover and clips above the cover to give the brake line some freedom to move to get the stock cover off. Clips were tightened around the brake line once the installation of the PML cover was finished. The bracket at the top was easy to reuse. He drained about 3 quarts and added 3.75 quarts.
