Richard's F–250 has a custom paint job on the body and he wanted a custom differential cover to match. Richard selected part number 10816 and matching front cover 10737 and did a custom powder coat in shiny red. To give your pickup a custom look, buy an as-cast differential cover. We irridite our covers so on arrival they are clean and ready to install or to let you be creative as Richard did with his. |
2001 F–350 with PML Differential Cover

Installations
Steve installed this PML rear differential cover on his 2013 F–150 V8 XLT SuperCrew 2WD. The installation was a simple bolt-on process. Even thought this cover is larger than stock, there were not any clearance issues.
The stock bolts with the brake line clips were re-used to maintain the brake line in its original location.Our thanks to Steve for installing our pan.
