Overview:
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, 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.
Features:
- Load Bolts for Additional Support for Bearing Caps
- Magnetic Drain Plug for Easy Servicing
- Additional .50-quart Fluid Capacity
- A356.0-T6 Aluminum Construction
- Over 65 Years of B&M Quality
- Lifetime Limited Warranty
- Machined B&M Logo

Beautiful Non-Glass Frame
Color: Bronze, Size: 12x16
Love this frame!! I'm so in love with the new type of frame backing this one had! I hate those frames that have those tiny thin metal tabs that stick out where you have to bend up/down to remove backing but not this one! It has these really easy to use metal springs that you push down & turn & it easy pops out! Wish frames all came w actual glass! I thought this one had glass but was wrong, it has the thin plexiglass type covering where you remove the clear stickers from front/back. It will work but because I have it used in a bathroom, I will need to get a glass replacement eventually. Love the gold color, it's a really pretty gold, not overly yellow. Overall, I think its a nice frame & such a great value.

Gorgeous Distressed Bronze Frame, Easy to Hang
Color: Bronze, Size: 18x24, Color: Bronze, Size: 18x24
This bronze frame looks really, really good—honestly, it passes for real bronze at a glance. It has a nice distressed finish that gives it some character without overdoing it.
It’s also surprisingly lightweight, which makes it much easier to hang on the wall. The overall build feels solid, and I don’t see any issues with it coming apart or feeling cheap.
I especially like the back—everything is well thought out, from the sawtooth hangers to the tabs that make it easy to open and insert your print.
I didn’t have my print yet to put in it, or I would’ve included a photo of it fully set up, but I added some pictures to show the detail and the back hardware.
Great-looking frame, well made, and easy to work with. Definitely happy with it.

Nice Frames
Color: Black, Size: 8x10
I purchased two of these frames in black. I was pleasantly surprised at how nice they are given the price was so low. I removed the film on both sides of the plexiglass as instructed and it was crystal clear. These are not high quality frames if that's what you are looking for.....real wood or glass. However, they are awesome for the price and what I needed them for. I would purchase them again.
