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

Great reef-safe, easy-to-apply sunscreen (comparison of three ThinkSport products)
Size: 6 Ounce (Pack of 1)
I will start by saying that I am used to traditional non-mineral sunscreens and tend to only buy physical/mineral-based sunscreens when I'm going to be in a tropical ocean and need something reef-safe, though more and more kids sunscreens are shifting to mineral-based. After quite a bit of research I settled on ThinkSport for my family's recent trip to Hawaii, and I'm very pleased with it. I brought and used three types of Thinksport sunscreen: Thinksport Kids lotion (yellow/orange and teal squeeze bottle), Thinksport adult lotion (Black, white, and orange squeeze bottle), and Thinksport adult spray (black, white and orange spray bottle). All protected us from sunburn and rubbed in to be invisible as long as skin was dry and free of visible hair (visible whiteness persisted around my husbands facial stubble and chest hair). The only difference between the kids lotion versus the adult lotion is scent--the kids version has a fruitier, more tropical but not-too-strong scent (possibly coconut and something else? it was hard to identify) that I found unobjectionable (though one if my kids wasn't a fan), and the adult lotion had a lighter, less sweet, more citrus-y scent (my son though maybe lime and mint, but I'm not sure that's accurate) that I LOVE. The adult spray had no discernible scent, so I suspect the kids spray might be fairly unscented as well. The easiest to apply by far was the spray--it sprays on white, but feels very light, rubs in easily, and becomes invisible quickly. I was a little worried about whether it could possibly be effective given how light and thin it felt, but it was! The lotions weren't thick for a lotion (but much thicker than the spray) and went on easily, but took more rubbing in to disappear than the spray (this is consistent with my experience with lotion vs spray in traditional sunscreens as well). Invisibility was harder to get after a second or third application or when skin was damp, but all-in-all I found all three Thinksport products to be superior to other mineral-based sunscreens I have tried in the past. In the future I'll probably buy the adult thinksport spray for my kids and husband (who all much prefer a spray-on sunscreen) and the adult thinksport lotion for myself (because I love the scent and don't mind rubbing it in).

Dependable sun protection for active days outdoors
Size: 6 Ounce (Pack of 1)
I like how this sunscreen provides reliable broad-spectrum protection and holds up well during outdoor activities. The zinc oxide formula gives me peace of mind, and I appreciate that it's water resistant and reef-safe. It applies smoothly for a mineral sunscreen and stays on effectively during sports, swimming, and long days in the sun. Overall, it's a trustworthy option for anyone looking for strong sun protection.

Clean product
Size: 3 Ounce (Pack of 1)
I only gave it 4 stars because of the smell. Of course it’s sunscreen so it’s going to have a chemical smell but this smell is just too strong for me. Other then that, it’s a great sunscreen. Does take some more rubbing in and be carful to rub it in really good or you’ll have white streaks all over your face. Leaves a bit of a white cast. You don’t need much.

Great quality
Size: 6 Ounce (Pack of 1)
Thinksport SPF 50+ Mineral Sunscreen with Zinc is a reliable, high‑protection option that feels lightweight and non‑greasy on the skin. It applies smoothly without leaving too much white cast for everyday use, and I love that it’s mineral‑based with zinc for strong UVA/UVB defense. Great for active days outdoors. Highly recommend for sensitive skin and safe sun coverage!

Brown skin approved!
Size: 6 Ounce (Pack of 1), Size: 6 Ounce (Pack of 1)
Does not leave a white cast, feels very light on the skin. Scanned on Yuka and was a 86/100 green zone! It’s so hard to find a sunscreen that isn’t trying to poison you, scanned all the sunscreen at Walmart and were rated a 1/100 through 6/100. Which brought me to Amazon. Thinksport has my vote on goodness and healthiness, would buy again!
