More Info:
Since most GL-5 gear oils for differentials are too slippery for manual transmissions, Red Line offers these products that ensure proper shifting while providing ultimate wear protection.
Red Line MT-90 High-Performance Gear Oil is a full-synthetic ester-based lubricant designed for use in manual transmissions and front-wheel-drive transaxles. This shear-stable formula resists breakdown for extended periods and offers more consistent viscosity in warm and cold temperatures for less gear noise and improved shifting. This fluid is less slippery for improved synchronizer coefficient of friction and offers stronger film strength for better wear protection.
- 75W90 GL-4 gear oil (similar to SAE 5W40/10W40 engine oil viscosity)
- Popular in Nissan, Mazda, Mitsubishi, VW/Audi, Lotus Elise/Exige, Toyota, Mendeola transmissions and Atlas transfer cases for Off Road
- Offers quicker shifts, perfect synchronizer coefficient of friction
- Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage
- High performance gear protection and longer synchro life
- Eliminates notchy shifting, even when cold
- Satisfies the gear oil viscosity requirements of 75W90, 80W90, 90 and motor oil viscosities of SAE 40, 10W40 and 15W40
- Recommended for GL-1, GL-3 and GL-4 applications, as well as where most special synchromesh fluids are specified
- Appropriate coefficient of friction for most manual transmission synchronizers (other's synthetic gear oils are often too slippery for proper synchro engagement)
- Red Line offers lubricants to pinpoint nearly every transmission application
- MT-LV, MTL, MT-85 & MT-90 are not for use in differentials with hypoid gears
- Excellent gear and synchro protection, balanced slipperiness for easier shifting in cold climates
- Excellent for high- and low-mile transmissions
- Compatible with petroleums and other synthetics

Surprising good - great quality for price.
Special Size: Wide Leg, Size: 6, Color: Ecru
These are great for the price. They run a little wide in the waist so I sized down from an 8 to a 6 and they fit perfect. They are a true wide leg - so don’t buy if you are looking for something more straight leg or flair. The quality of the denim is very nice. I’m actually surprised and the quality. These do not feel stretchy which is good for the style. Very happy. Hopefully they hold up after washing

Excellant value
Special Size: Wide Leg Crop, Size: 14, Color: Rinse, Special Size: Wide Leg Crop, Size: 14, Color: Rinse
Purchased the “cropped” length. I am 5ft 3.5 inch. Weight 170lbs (42 inch hip/38 inch waist) normally wear a size 10/12 or 31 in jeans, depending on the brand. I ordered up at 14 for these based on other reviewers. (When held up to other jeans they were the same as a Talbots 10 at the waist)
Prewash they felt good, a little big& length hit at the top of my foot. After wash and dry, the fit was almost perfect and the length was at lower ankle. Ordering up is probably the right choice, although I think I could have been comfortable in a 12 (with no drying). They are a tad bit too long for a “cropped” look IMO. The wide leg is a true wide leg and falls straight from the waist. The material is heavy and there is almost no give/stretch - so a traditional denim. This is the dark blue and it is a true dark blue. You can’t beat the price, excellent value.

Cropped ones are better, size issue with full length pants
Special Size: Wide Leg, Size: 18, Color: Authentic Medium Wash
These are very small in the waist and about 8 inches too long (and I'm not even that short). Very well constructed though so I'll keep them on hand as I'm on a weight loss journey. These were an 18 and fit more like a larger 14.
The cropped ones are AWESOME. I ordered a second pair in a different color. They fit absolutely perfectly and hit me around the ankle length wise. Adore them.

GET THESE JEANS!!
Special Size: Wide Leg Crop, Size: 12, Color: Iced Blue Light Wash, Special Size: Wide Leg Crop, Size: 12, Color: Iced Blue Light Wash
I ordered these jeans because they were recommended by a youtube influencer and I have 0 regrets! They are a fairly heavy denim with just the right amount of stretch to them. I'd consider them to be mid to high waisted since the closure is right below my belly button. However, if I hike them up a bit they sit right above the belly button. I washed and dried them with little to no shrinkage. Length-wise they're slightly cropped on me, and fall right above the ankle. These jeans are honestly SO versatile because they look great with ballet flats, heels, tennis shoes, AND suede or leather ankle boots! Since I couldn't decide, I ordered them in two colors (iced blue light wash & medium blue vintage), and I love them both!! For reference, I'm 5'6 and 170 lbs. I ordered size 12 and they fit great. Highly recommend. You CANNOT beat the price for this level of quality in my opinion!!

My everyday Jean
Special Size: Wide Leg Crop, Size: 8, Color: Medium Blue Vintage
They don’t have much of a stretch to them but they do get a bit more lose around the waist when you wearing often. Got a size 8 was tight but after a few uses they got perfect. Be Definitely is a thick jean material tucks in any unwanted over hang. Don’t tumble dry they do shrink
