aFe Powers new front-end differential cover brings performance engineering to the protection of your trucks front-end. This differential cover has a 3-1/2 quart lube capacity (factory cover holds 2-1/2 quarts) at the factory fluid level line, a magnetic drain plug and a magnetic fill plug to remove unwanted debris. Built-in external fins transfer heat from the fluid to the outside air for maximum cooling. aFe has also designed a large oil level sight glass with calibration plug set to the factory fluid level to eliminate overfilling. This differential cover is constructed out of durable die-cast A380 aluminum with reinforced ribs and a wrinkle black powder-coating for maximum strength and style. When it comes to engineering for power, performance, protection and value, aFe Power is the only choice.

Our engineers designed the line of Hi-Tek differential covers to not only look good but address a number of weaknesses of the factory-stamped steel covers. First, they started by constructing the covers of thick A356.0-T6 aluminum, which dissipates heat much faster than the factory steel unit keeping the fluid temperature lower under high-stress loads vs. a steel cover. Then for added durability, we added a reinforced center bar for extra strength along with load bolts to help prevent bearing cap deflection under severe loads. The internal shape of the cover retains the smooth round back internally to help keep the fluid flow going over the ring gear to properly lubricate and cool the bearings and ring & pinion gears. Additional features include a magnetic drain plug for catching ferrous metal particles, a machined B&M logo, and all necessary hardware and easy-to-follow detailed instructions for a quick and simple installation you can do at home.
