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.

Comfortable, Colorful, Soft, Affordable.
Size: Large, Color: Ice Blue, Number of Items: 1
These T Shirts are as good as it gets especially at the price point. All cotton, very soft, very colorful. Wash well. If you don’t want them to shrink, I suggest air drying them. I had an XL one for years and pretty much ignored it. Found it again and it’s amazing to wear to bed or around the house. At
These prices if you need or want a T shirt, this is the one to get.

The Perfect Tee Shirt
Size: X-Large, Color: White, Number of Items: 2
I bought one of these shirts to see if they’re as good as the customer reviews suggest. They most certainly are! They have a nice weight, a great fitting collar, and the shirts have a generous length so they stay tucked in. The sleeves are longer than normal tee shirts, which I really appreciate. These shirts are such high quality, and such an amazing bargain, that I bought four more!

This tee shirt has no side seams.
Size: X-Large, Color: True Navy, Number of Items: 1
This 100% cotton tee shirt is a nice weight & true color, sits close to neck. However, I planned to use this for my yoga class & put in some side slits for a better fit & there are none! Also, nothing in the description says what gender it is for, although the photo shows a guy. There was no contact info to call about this question. For some reason this never came up in my search for a cotton tee shirt & the only way I came across it was to google for a comparison for Life is Good shirts which are pricey. I won't be able to use it for yoga class.

Consider ordering one size larger than you normally wear.
Size: Medium, Color: Ice Blue, Number of Items: 1
Excellent quality shirts available in so many colors. Take note though....the sizes do run true to size BUT more of an athletic slimmer fit. If you don't want to be "tight" then order one size larger. If you're very athletic and fit....then order true to your normal size, just know the shirt will be "form fitting" and not loose.
