About this item
Product details
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 the gears and bearings. Additional features include a magnetic drain plug for catching ferrous metal particles, natural finish, 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. Note: Gasket not included.;
- A356.0-T6 Aluminum Construction

Great Diff Cover
Pit this on a 03 Ford Ranger. 4:10 gearing. 31 spline. Worked great. No rubbing like another one I tried. Looks good. Took 3.5 quarts total to fill since the cover was larger. Drain plug means easy fluid swap.
Quality differential cover
I bought this cover because I was putting a powertrax no slip locker in my 1wd f150, and wanted to give the bearing caps some additional support since there would be increased stress do to the addition of the locker , the addition of having more fluid capacity made replacing oil easier since it increased its capacity up to an even three quarts. Great part ,great quality. My only gripe is it only came with half the bolts so I had to go buy my own, I'm sure it was a mistake. Still a great quality part at a great price from Jegs. Includes instructions.
8.8 Cover in a 66'
Used this cover in my 66' Mustang with a 8.8 rear end that I installed. No clearance issues fit great, no leaks, and looks good.
