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.

These are a travel must!
Size: 15 Combo Travel Size
We recently took a trip to Japan and South Korea with our 3 kids, and needed to bring all their clothes for 2 weeks, with as few suitcases as possible. These bags were a life saver! We were able to fit so much more stuff in our suitcases with these bags. I don’t know how we would have brought everything without them. We would have had to bring at least one, probably two suitcases more. Easy to use - the vacuum is compact so you can bring it with you, but super powerful and works quickly. Remember to charge it after you use it for when you pack back up. But, you can manually push out the air as well if you’re in a pinch.

More pros than cons, very convenient, but durability is an issue.
Size: 15 Combo Travel Size
Pros: I think that this is a good product. I've had it for several weeks and travel every week for work. It's a good design and the vacuum pump is ergonomic and reliable, in my experience. Charges relatively quickly at home and I'm not sure how long the charge lasts, because it's convenient with a USB-C port, so I charged whenever the charge got to 3 bars. My experience is that dress shirts maintain the pressing if folded and packed neatly. They're creased, but hang them in the hotel bathroom and the steam from a shower loosens the wrinkles nicely. Cons: durability. The bags are pretty thin and after 3 or 4 trips the seal in the bag(s) can become compromised. I suspect the leaks are tiny and in the actual bag vs. the seal. With regular use, this was in only two of the fifteen bags. The double zip lock is really durable. FOR CAMPING: they were great for motorcycle camping, however the durability became an issue. I was camping along a lake and took some care with the bags, but admittedly was a little harder on them than I could have been. I took extra bags just in case, and am glad I did. Three of the 6 bags I took slowly lost the vacuum. If you're using them for camping, pack extras. They're inexpensive enough to continue to buy replacements periodically and you do get a lot. TIPS: pack the vacuum in the suitcase with the bags. Pack the bags with a complete outfit for each day. The temptation is to pack shirts in one bag, socks/underwear in the other, etc. It's more difficult to repack dirty clothes that way, but if you have each day in its own bag you just use each one for a dirty laundry bag.

Absolutely Perfect?!!
Size: 15 Combo Travel Size, Size: 15 Combo Travel Size
AMAZING!! This made packing soooo easy and such a breeze!! My suitcase was organized & I had everything that I needed for my trip. It has a great suction & comes with several red strips (I’ll call them) to ensure a tight seal before suctioning the air out. The bags comes on several different sizes & hold quite a bit of items in the big bag which held out hoodies & sweatsuits. Vacuum it’s not loud at all. Lightweight but packs power. This is a game changer! Very durable & great quality!! I’d highly recommend this item.

Over packer approved! GOODBYE checked bag fees!!
Size: 9 Combo Travel Size
These were incredible for our recent flight to Tampa. I’m an overpacker by nature, and we normally have to check at least one bag, but these completely changed that. We were able to fit everything into our carry-ons and backpacks with room to spare, which even saved us from paying a checked bag fee. The vacuum came already charged, and I still haven’t needed to recharge it, which was a nice bonus. It also comes with a small travel bag to keep the charging cord together, which made it easy to stay organized. The suction is strong and works quickly. I packed one bag completely full and it compressed it down to about half the size. The bags are durable and easy to seal, even without using the plastic zipper clips. As long as they’re fully sealed, they stay compressed and don’t slowly let air back in. We unpacked everything at the hotel and stored the empty bags in our suitcases, then reused them to pack for the trip home with no issues. The vacuum isn’t silent, but it’s not overly loud either. I’d compare it to being quieter than a typical hair dryer. This is such a game changer for travel and saving space. I’ll definitely be using these for every trip.

Extremely well made travel vacuum bags
Size: 9 Combo Travel Size
These are great kits for Travel and storage. I now have two sets. The pump works very well. Small enough for carry on. One very small dislike, There are small clips that slide across the top closer. But nothing to stop them either end. So may fall off. But I would highly recommend them. 9 out of 10 for me.
