aFe Power 86-11 ford diesel rear differential cover, machined fins, fits ford 12-10.25 & 10.50 axles

aFe Pro Series differential covers are constructed out of durable die-cast A380 aluminum with a reinforced rib design for maximum strength and styling. aFes specially designed external fins (and models that also have internal fins) transfer heat from the fluid to the outside air for maximum cooling. Covers feature wrinkle black powdercoatings with or without machined ribs. The Pro Series covers include deep-reach magnetic dip sticks for maximum protection and large pre-installed oil level sight glasses with calibration plugs set to the factory fluid level to eliminate overfilling. aFe engineers power, performance, and protection, along with value to fit your rig with the only logical choice--Pro Series differential covers.
