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.

Comfortable shoes with accurate sizing
Size: 10, Color: Black Leather
The Clarks Men’s Tilden Cap are very good shoes. They look elegant and are comfortable for daily wear or more formal occasions. One thing I appreciated is that the size chart is accurate and consistent, so the fit was exactly as expected. This makes it much easier to order the correct size online. Overall, good quality, comfortable, and reliable sizing. A solid choice if you’re looking for classic dress shoes.

Price And Comfort Conscious? Buy These!
Size: 10.5, Color: Black Leather
For the price, these are a great value. Super comfortable. I was looking for a shoe I could wear all day. Usually, this means you need rubber soles (no wood). You can't resole many one-piece rubber sole heels, but that's fine. Rarely do I do that since the top of the shoe shows so much wear, it makes me want to get a new pair of shoes no matter how much shoe-shining I do. I own Saks 5th Avenue brand shoes, Cole Haan, and many other pricey shoes. Sure these Clark's don't look as sharp as Italian-made shoes. But Clark's are comfortable. With this particular shoe, they struck the right balance between fashionable and functional--a rare feat indeed! My feet are normal width (D). Half my shoes are 11, the other 10.5. I got these in 10.5 and they fit fine. The toe box is only slightly snug, but I'm hoping they will stretch out in a month or so. I probably should have done 11's. If you are in the middle like me, err on a half size larger. I had a chance to try these on at a store (hesitated to buy at first). The toe box is long and the 11 seemed kind of big, so I went down a notch. In hindsight, 11 was the right size. I couple things I could do without are the side slits that have elastic. They are minimal though. And at the end of the day, you probably don't need to untie your shoes to kick these off, but I don't recommend that. I was also not crazy about the inner lining. It kind of looks like pleather, to be totally honest. Either that or it's super thin and shiny leather. They have a cheap look to them on the inside, but who cares because you don't see them. Overall, great shoes. Way to go Clark! These ones are winners and they look great with suit pants or nice jeans.

Good quality
Size: 13, Color: Black Leather, Size: 13, Color: Black Leather
These fit true to size in length but like any cap toe Oxford, you will have a lil more space at the tip. The width is a little narrow for regular feet but still fit properly. If you have wide feet definitely go with the wide option. The leather feels nice and soft. They are fairly comfortable. I even compared them to cap toe Nunn Bush shoes I have and they’re more comfy. The front of the shoe/tongue doesn’t dig into my ankle like the Nunn Bush pair does.

Good deal
Size: 8.5, Color: Black Leather
Honestly for the price there hard to beat. They look nice and are comfortable indeed, I like the silent step "non clackers" . For the size I'll recommend your normal size as they have a built in stretch part for extra comfort unless you know you have wide feet then go for the W, my 8 1/2 (non wide) fit perfectly without an issue. I'm just surprised that they came not in a box, there wrapped up well though didn't come damaged. For fancy shoes that don't come in a box there pretty good. 👍

The perfect work shoe
Size: 13, Color: Black Leather
I wear dress shoes everyday and I’m on my feet a lot. My wife is the same way and would always praise Clarks, but I didn’t think much of it. I’d always get Nunn Bush or something like that, but they weren’t comfortable or last very long. I happened to be at a Clarks store that was closing one time and picked up a pair of these and boy did everything change that day. Not only are they comfortable they last a long time. I get about one pair a year. That doesn’t mean they only last a year, I just try to keep a nice looking pair. I can wear them all day and my feet don’t hurt. And you get all the comfort without the bulkiness of other comfort footwear companies. They fit nice and don’t pinch or rub anywhere. They are definitely worth the full price, but they go on sale regularly to an even better deal so keep an eye out.
