Description

GEAR-X 75/90W R Racing Gear OilGEAR X 75w90HD synthetic gear oil is designed to take 80% more load carrying capabilities than its competitors. GEAR X 75w90HD is compounded with the most recently developed additive system to provide the ultimate in gear protection, from an E. P. wear, corrosive wear, and shock load wear standpoint. A friction modifier is also employed to reduce sliding friction resulting in lower energy requirements, thus less drag, lower fuel consumption, and more

GEAR-X 75w90HD synthetic gear oil is designed to take 80% more load carrying capabilities than its competitors. GEAR-X 75w90HD is compounded with the most recently developed additive system to provide the ultimate in gear protection, from an E.P. wear, corrosive wear, and shock load wear standpoint. A friction modifier is also employed to reduce sliding friction resulting in lower energy requirements, thus less drag, lower fuel consumption, and more horsepower.

GEAR-X synthetic gear oils offer both cold temperature advantages (Pour Point is -45°F) and high temperature stability (Flash Point is 480°F). As a multigrade product meeting the low temperature viscosity requirements of a SAE 75 W grade gear oil, but also meeting the viscosity requirement of SAE 90 grade at operating temperatures. The base is a unique combination of synthetic components that permits meeting SAE 75w90 viscosity requirements without the need for a viscosity improver.

Extended Lubricant Utility

GEAR-X 75w90HD gear oil spans a wide range of viscosity classifications making it the first truly dependable “All Seasons” gear oil. This means it will flow and properly lubricate at the lowest winter temperature while providing the film strength for heavy duty operations during boiling hot summer driving conditions. The advantages of such an oil have long been recognized as evidenced by the universal acceptance of multiviscosity motor oils.

Many lubricant manufacturers have previously offered multi-graded gear oils. These oils have been formulated with the conventional viscosity index improvers used to produce multi-vis oils. But these additives, which work so well in motor oils, will not

Withstand the extreme pressures and shearing forces encountered in normal gear operation. Consequently, the advantages of multi-grading are lost after only a few thousand miles of service.

The new additive system used in GEAR-X 75w90RHD is almost totally resistant to these forces. GEAR-X 75w90RHD shows virtually no change in grade even after 50,000 miles of more of operation in heavily loaded, hypoid axle drives. This means that in addition to the fuel savings generated, GEAR-X will provide true year round performance in all climates from arctic cold to desert heat. Additionally, it will provide superior all around performance in virtually all applications calling for gear oil rated from GL-2 through GL-6, in any viscosity grade from 75w, 80w90, or 90w. This can result in reduced gear oil inventories allowing a single lubricant to replace as many as 4 or 5 separate oils.

Applications:

GEAR-X 75w90HD gear oil is recommended for automotive type gear service in manual transmissions, differentials, transfer cases, over-drive units, oil lubricated wheel bearing, oil lubricated universal joints, steering gear boxes, or any other gear unit calling for a high quality heavy duty 75w90 hypoid type gear oil. GEAR-X.

75w90HD is also recommended for use in all limited slip type differential designs. GEAR-X 75w90HD meets or exceeds performance requirements of Military Specification Mil-L-2105B, Mil-L2105-C, and API Specification GL-5, GL-6, and SAE Classification J306a.

GEAR-X Synthetic Gear Lubricant has been race-proven in endurance competitions all over the world.

As advertised for once! Lol
Color: Cooling Blue Cover, Size: Queen (Pack of 2), Color: Cooling Blue Cover, Size: Queen (Pack of 2)
Queen size set of 2 pillows, I'm giving it 5stars first bc it has a good length and width!! If you've ever bought memory foam pillows before you know some are small!! Anyways after having it for 5nights, we loved that me and my huddy could adjust the Thickness amount we had in it to our needs, me needing a thick pillow and my husband needing a flatter one. So this was perfect for that. So far its nice to sleep on, stays cool, doesnt get hot. I would say its on the frimer side but softer the more foam you take out! Really its just good for the amount you spend!! Will it last 10years probably not but what does now a days. This is the only time my huddy n I bought the same pillow and both love it so I'm just still in shock it worked out so well!!

Adjustable pillows
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
I love these because they don't go flat. You can pull out whatever you need to make them comfy for you. They come in two different layers. So you have that protective cover over the main case that holds the memory foam. They're amazing to sleep on. I have had these last for years without going flat. If you hate flat pillows this is the way to go. They are very easy to wash. You just have to separate layers. They are very thick, you can adjust the thickness. Everyone in my house has at least one. They are worth the money. I have never had to replace them, because they went flat.

Good pillows
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
Takes some getting used to but and the cooling doesn’t last very long in my opinion, but overall amazing comfy pillows. The materials are good and are washable. I mostly stopped waking up with a stiff neck and back.

Believe the Reviews
Color: Cooling Blue Cover, Size: King (Pack of 2)
I purchased these pillows because we were in need of new pillows, I previously had allswell pillows which were from walmart and they were good to start but now they tragically became very sparse and it started to effect my sleep so I saw these after careful review on other pillows and reviews I came across these and I saw some reviews and videos and I ordered them.. first they are king size we ordered they are perfect for the bed, they are plump and soft, they are memory foam which has always worked out for me for support and kept it’s shape these are great it did have a little smell I guess from packaging but other than that they are a huge upgrade from what we had before! I’m excited because they are cooling too! for the price point can’t beat it and this is coming from someone who was about to spend money on a purple pillow this will be good for now definitely buy it.

Inconsistent
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
Ive ordered two different batches of these pillows, the first was a 2 pack, the second batch was a 4 pack. The pillows that came in the 2 pack have a different quality to them. The memory foam feels thicker, takes long to depress and to spring back to form. It offers more resistance, a heavier odor (at the start), and was the pillow that I fell in love with. Things changed when I ordered the 4 pack a couple months later. There was an inconsistency between the foam in these two different batches. both sets of pillows are comfortable. The first batch being firmer means I had to remove more foam before it became comfortable but the 2nd batch being more springy, I was able to keep all the foam inside. I docked a couple stars because I’m not able to provide a consistent experience with these pillows across all three beds in my home. If you need a pillow, order a set and be happy. If you want a bunch of memory foam pillows throughout your house, maybe look elsewhere as these may not all be identical.
