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.

Satisfied
I’ve been hearing all about the benefits of snail mucin for skin care, and now after trying Jasclair snail mucin hydrating serum for post derma-planing, it is easy to understand what all the hype is about when it comes to snail mucin. After derma-planing, it is super hydrating and soothing to put on, and my skin retains that moisture long after. But although it’s great for after derma-planing, it works just as well as a daily serum. For anyone wondering - yes it is a little bit slimy, but it’s more just out of the ordinary for what one is used to with a serum, not anything excessive. The smooth hydrated texture of my skin afterwards it’s perfect for makeup application and this serum works well underneath my make up, at least in part because it absorbs so well. A little bit goes a long way and this is now a must have as part of my beauty routine. I would highly recommend this snail serum after derma-planing and overall skin rejuvenation.

Great results
Love using this item at night. It’s kind of thick but if put on before bed it is all soaked in by morning. Face is so smooth after using this product before bed. Easy to use and completely clear in color.
