SINGLE QUARTS -SOLD INDIVIDUALLY

Product Description
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.

Cool-temperature outer cover
Set name: UltraCool Pillow 2-Pack, King - Soft/Medium, Item length width: 40.0 Inches
The pillows (set of2) are easily fluffed and adjusted to personal desire. The outer cover is cool to the touch. I do not feel "cooler" with the pillow, but it does not get hot like some. I'm a side sleeper and sleep comfortably with the Slumber Cloud. I would buy these again. Con: pillow cover is slick, so pillow cases slide off.

not cooling for post menopause
Set name: UltraCool Pillow, Standard - Medium/Firm Firmness, Item length width: 30.0 Inches
As a post menopausal person I did not find this cooling at all. The material is memory foam which holds heat but more importantly my head sinks in so that half of it is always surrounded by the pillow, trapping heat. It IS a supportive, soft and comfy pillow. For cooling though, I found it better to buy a firmer, thinner pillow which keeps my head from sinking into it, allowing heat to dissipate.

Nice and squishy
Set name: UltraCool Pillow, Standard - Soft/Medium Firmness, Item length width: 30.0 Inches
Not really a "cooling" pillow, but better than a standard or or fiber filled pillow. All these types of pillows and other bed linens are initially cool to the touch, but they quickly heat up to match your body temperature. Although the technology currently does not exist to maintain constant cooling, pillows like this are a good compromise for now. It's nice and soft and is a good value for the price.

Doesn’t stay cool long
Set name: UltraCool Pillow, Standard - Soft/Medium Firmness, Item length width: 30.0 Inches
The pillow was a little softer than I expected. It’s cool at first but at least for me heats up fast.
