Mishimoto 01-05 Chevrolet/GMC 6.6L Duramax (LB7/LLY) Transmission Cooler Line KitEvery truck owner knows that it doesn't matter how powerful or reliable your engine is if you can't get any power to the wheels. The transmission mated to your 2001 2005 LB7 LLY Duramax is essential to everything your truck does, and keeping it cool is crucial. Upgrading your transmission cooler with a Mishimoto performance transmission cooler is a good start, but the fluid still needs to get to the cooler. That's where this 2001 2005 GM 6. 6L Duramax

Every truck owner knows that it doesn't matter how powerful or reliable your engine is if you can't get any power to the wheels. The transmission mated to your 2001-2005 LB7/LLY Duramax is essential to everything your truck does, and keeping it cool is crucial. Upgrading your transmission cooler with a Mishimoto performance transmission cooler is a good start, but the fluid still needs to get to the cooler. That's where this 2001-2005 GM 6.6L Duramax (LB7/LLY) Transmission Line Kit comes in. These high performance lines are constructed with a durable PTFE line that's wrapped in a high-strength nylon braid. The PTFE line is extremely oil and heat resistant for durability in even the harshest environments. To protect the lines against higher line pressures that come with performance transmissions, We've wrapped them in braided high-strength nylon. This wrap prevents expansion and further protects the lines from abrasion. Finally, these lines are capped off with -10AN fittings for a secure and leak-free connection. Like all Mishimoto Duramax products, these transmission lines are backed by our Mishimoto Lifetime Warranty for a lifetime of performance.

It’s ridiculous…
Size: King (Pack of 2), Style: Medium, Configuration: Hometextile
When I got these pillows I was a little disappointed that they appeared to be a little lumpy. I fluffed and let them rest for a couple of days to see if they’d poof up. Finally figured this was as good as they were going to get. First night sleeping with them…my life has changed! I typically like a lot of pillows. I’m usually a restless sleeper. I fell asleep quickly and slept through the night for the first time since I can remember. No aches and pains as usual. It’s ridiculous that a couple of pillows could have made such a difference in my quality of sleep. Who knew?! I’ll buy these for every bed in the house.

Great quality

LOVE this pillow. Soft and supportive for sitting against. Too big for sleeping but great for lounging.

Do not buy, I recommend looking for something else
Size: King (Pack of 2), Style: Medium, Configuration: Hometextile
I don't like the quality of those pillows. They don't have any support, super flat, it's like just using the pillow sheet without the pillow. I honestly don't get why this could even be a product. Amazon Basics brand is veryh nice but this one was a very bad one. I usually go with anything but this was worst than cheap airbnb pillows.

Great
Size: King (Pack of 2), Style: Medium, Configuration: Hometextile
The medium density support is exactly as advertised and provides more support and firmness. The pillow is taller because of the density so maybe not great for stomach sleepers but works well for back and side sleeping. I bought this because I tried the same pillow at my sister’s house and woke up without neck pain for the first time in forever. Honestly better than my $100 pillow.

These are firm pillows not medium as described.
Size: King (Pack of 2), Style: Medium, Configuration: Hometextile
These pillows are much too firm to be medium density as described. They are too stuffed full of filling. They barely give when my head is on them, so my neck ends up twisted. And they are ridiculously heavy. The filling is also uneven. I wish there was a zero stars option. Definitely returning them.
