Red Line Synthetic ShockProof™ Gear Oil provides unequalled protection for high performance differentials and transmissions which are heavily loaded or which see shock loading. This revolutionary lubricant is completely different from conventional lubricant technology in several ways. The viscosity characteristics are significantly improved. Gear teeth need high viscosity at high temperatures to prevent metal to metal contact and a low viscosity when cold to reduce fluid friction. The ShockProof™ chemistry significantly reduces the thinning effect of high temperatures. The Heavy can be rated as a 75W250 Gear Oil, but has the lower internal fluid friction of an SAE 75W90. The Lightweight can be rated as a 75W140 Gear Oil, but has the lower internal fluid friction of an SAE 30 motor oil. The SuperLight can be rated as a 70W90 Gear Oil, but has the lower internal fluid friction of an Automatic Transmission Fluid. These ShockProof™ lubricants provide much greater viscosity in the thin layers between the gear teeth, but have very low internal fluid friction, which means very little power loss for the protection achieved. ShockProof™ Gear Oil has a 40 Percent lower coefficient of friction and 250 Percent the load carrying capacity compared to conventional gear oils, which means that metal to metal friction is greatly reduced. Temperature reductions between 25 to 75 Degree Fahrenheit are common in circle track, road racing, and off-road racing. Improved durability in high performance use is the primary benefit of the Heavy ShockProof™ and along with the improved durability is an improvement in efficiency, but if further improvements in efficiency are desired, and durability is not a major concern, Lightweight and SuperLight ShockProof™ can be used. Red Line ShockProof™ can be used in conventional, limited slip, or locker differentials. Red Line ShockProof™ is designed for use in competition differentials and transmissions.

Keeps phone cool off phone charging pads!
I bought this magnetic phone mount for my Tesla Model X and it works great. The magnet is extremely strong and holds my phone securely, even over bumps and rough roads. Once it’s attached, the phone doesn’t move at all.
Installation was quick and easy, and it fits the Model X interior nicely without looking out of place. It keeps the phone in a convenient spot for navigation or music without blocking the main screen.
Overall, it’s a solid, well-made mount that does exactly what it’s supposed to do. If you have a Model X and want a strong magnetic phone mount, this is a great buy.

Super Strong Magnet & Perfect Fit for My Tesla
I’m really happy with this Tesla phone mount. The magnet is extremely strong—my phone stays in place even when I’m driving on bumpy roads. Installation was quick and easy, and it attaches securely without blocking the screen or getting in the way.
I love how clean and minimal it looks in the car. The rotation is smooth, and it makes it easy to check maps or take calls hands-free.
If you want a reliable and sturdy phone mount that matches the Tesla interior, this one is perfect. Highly recommend!

Good quality, outstanding customer service
The mount is stylish; it looks great in a Tesla. The quality is good. However, the 2025 version broke after 1 year of use, which they fixed in 2026. The customer service is great!

10/10
I picked up the Tesla Phone Mount MagSafe Car Mount for my car, and it’s been fantastic. The magnetic strength is impressive — even on bumpy roads my phone stays firmly in place without shifting or slipping. This mount works smoothly with my iPhone (MagSafe cases snap right on), and it’s also easy to use with other phones when I switch drivers.
Installation was quick and simple — just stick it where you want it and you’re ready. The mount holds the phone at a great viewing angle for navigation and calls, and I love being able to pop the phone on and off with one hand. The magnets feel strong enough that I don’t worry about the phone falling even during quick turns.
Overall, this MagSafe mount has been reliable, secure, and convenient — a great upgrade for everyday driving.

Good Mount / Poorly Connected Magnet
Good product. It fits well on my Model Y screen. It worked fine for 3 months. but then the magnet became loose from the ring. I like the product so instead of discarding it thought of using glue to stick the magnet back to the ring. BUT it didn’t work. So now it has been a frustrating experience. I may choose to discard a product that has a strong mount, but the one important part (magnet) not working correctly.
