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

Water bottle
Color: Shy Marshmallow, Size: 24 Ounces
My son had to have this water bottle and at first I was like what's all the hype about but I know now bc it literally the best water bottle, it super easy to clean, its versatile, it keeps your drink cold all day, the lid is amazing bc there's no leakage at all and you can use a straw or the drinking part for your mouth, great value for the money

great water bottle, doesn't leak
Color: Camo Cool, Size: 24 Ounces
Headline: Finally, a Water Bottle That Lives Up to the Hype!⭐⭐⭐⭐⭐"I’ve tried almost every popular water bottle brand out there, and the Owala FreeSip is genuinely in a league of its own. The 2-in-1 spout is a game-changer—I love being able to sip upright through the straw or tilt it back to chug. It makes drinking water so much easier.It’s completely leakproof when locked, which I’ve tested in my gym bag multiple times. Plus, the cover keeps the mouthpiece sanitary. It keeps my water ice-cold for over 24 hours, even sitting in a hot car. And let's talk about the colors—they are so fun and vibrant. I got the 24oz, and it fits perfectly in my cup holder. If you’re on the fence, just buy it!"

Great Water Bottle but failed after one year.
Color: Foggy Tide, Size: 32 Ounces
I purchased this Owala water bottle a little over a year ago and it was in my top favorites. The flip-up lid is a great feature, and I like that you can use it with or without the straw. It’s completely leak-proof, comfortable to carry, and has held up well with daily use. My only complaint had been that it doesn’t fit in most standard cup holders.
But after about a year, I did notice that it stopped keeping my water cold as long as it used to, and the ice began melting much faster. I reached out to Owala customer service but unfortunately never received a response.
Even with that issue, I still prefer the lid design over brands like Yeti or RTIC, so I would consider purchasing another Owala in the future. If you value a convenient, leak-proof lid design, it’s definitely worth considering. I just sincerely hope the insulation lasts longer on the next one.

The BEST water bottle on the market!
Color: Denim, Size: 32 Ounces
I am in love with this water bottle! I take it everywhere with me, and I love that it has a built-in straw. The color is perfect as well. It motivates me to get my water intake in, and it helps me meet my fitness goals. It is easily washed in the dishwasher, and I don't have to worry about it breaking. It keeps the temperature of my water perfect- whether I add ice or not. It is sturdy but not too heavy.

This mattress cover is great! Well worth your money
Size: Twin XL, Style: 1 Green
This mattress cover is so comfortable. I am scheduled for back surgery in a week so when I find something I can sleep on and call it comfortable you best believe it is! It fits well, it’s pretty and it’s very fluffy. Seems to be made very well. I am confident that I’ll get a lot of wear out of it.
