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.

Item received not as pictured - beware
Item not as described. The navy version I ordered showed a colored zipper and a print pattern inside the collar in the description but the one I received is solid navy in color. Not what I wanted or ordered. It fit fine and I liked the weight of the material as it is a little heavier than another Maelreg shirt I ordered which had the same description. Be careful when ordering as the color and weight of the material is certainly not accurate.

sleeves long
I'm 5'6" and stocky but the sleeves are too long and slip over to rest half way down my hand. If your 5'9 or taller you will be fine.
