Red Line Gear Oils are designed to provide excellent low temperature characteristics and improved gear protection at higher temperatures. Red Line Gear Oils will reduce differential temperatures 10 to 70 Degree Fahrenheit. Efficiency improvements between 1 to 5 Percent are typical. The synthetic base stocks used have tremendous thermal stability and provide the best film strength available. The unique combination of base stocks and additives allow Red Line gear oils to carry higher loads compared to petroleum lubricants. The stability of these products allow them to be used for extended periods. Red Line 75W90 Gear Oil provides excellent protection in nearly all differentials, conventional and limited slip, in both racing and street use. 75W90NS and 75W140NS can be used in certain limited slip units in racing to lock up the differential. 80W140 should be used in commercial hauling, problem limited slip units, racing applications which see tremendous torque at low speeds, and where noise deadening is desired. Lightweight or SuperLight can be used to obtain maximum power transfer in racing differentials which do not see extremely high temperatures. If "chattering" occurs with any of these lubricants, Red Line Limited Slip Friction Modifier can be used to eliminate the stick/slip action and reduce the noise. This additive should not be necessary in the 75W90, 75W140 or the 80W140 Gear Oils, since they already contain this additive, but in some units more is required. Too much friction modifier can reduce the lockup in limited slip units, so it should only be used if needed.

Price is right. Soft and squishy night for my chonk of a dog. She’s a big girl, weighs 140lbs. Fits her size nice. Treat your furbaby to a comfortable bed.

Nice doggy beds for the fur-babies!
Size: 41.3 x 27.5, Color: Grey, Size: 41.3 x 27.5, Color: Grey
This is nice, soft and fluffy, the fur-babies seem to love it. It does shed a lot so far. Females have been fluffing it themselves (dig/scratching) and has seem to be holding up well. These arrived vacuumed sealed. I was a little worried there would be a strong scent but was pleasantly surprised they aired out very well. I think these will be a nice addition to my fur-babies kennel. I only wished I would have sized up one more for a better fit for my kennel that’s interiorly 53x45. I think these 47x35 instead of 41x27 would have fit better. Other than the shedding and (my fault) the sizing I think they are great. I think a removable cover would have been nice but these are priced right I could always just buy again if need be.

Very happy!
Size: 41.3 x 27.5, Color: Grey
Buy this bed! My fur son is a destroyer.
Toys, balls, beds. Nothing is safe.
Knock on wood, this bed has held up to his destructive behavior.
And it’s so fluffy!
It is big enough that I don’t think it’s going to fit in my washer. I will have to take it to the laundry mat to wash it eventually.
At that point I will update on true durability.
But all in all I find it to be a quality purchase.

Doo
Size: 35.4 x 23.6, Color: Grey
This dog bed is super fluffy. The cat loves it also. Size was perfect for my med dog she weighs 49lb. We have had it for month or so and both the dog and cat use it over there old bed. It has remained super fluffy. Worth the bang for the buck!
