Suffering from poor performance and reduced fuel economy resulting from oversized tires?
A Nitro gear change will help get that performance and economy back!
If you've fitted larger tires to your vehicle then you are likely experiencing a loss in performance, fuel economy, and more constant transmission gear "hunting" - This is because the larger tires reduce your engine's RPMs below the optimal power band. Re-gearing the differentials in your vehicle is the only way to get your vehicle back into its optimal operating RPM range, thus improving performance and reducing strain on your vehicle's drivetrain. This is especially important for today's vehicles as they feature tall factory gearing and overdrive transmissions which are less tolerant to increase in tire size or the weight of added accessories.
It's a common misconception that gear changes are reserved only to hardcore off-roaders or trucks with huge tires. However, re-gearing is one of the single most beneficial modifications you can make to keep the performance, economy, and durability of your daily-driven 4x4. This is a mod for anyone with larger tires, increased weight, or for increased performance on stock vehicles for towing or increased acceleration.
We at Nitro Gear & Axle realize the difficulty for the average consumer or install shop to compile the list of parts and prices required when doing a gear change. To make it easier for everyone the experts at Nitro are introducing an industry first- "Gear Packages" for many popular 4x4 Fits. One part number. One price. One click away.

Meh
Color: Black
It's ok. I got it because it looked like it has more cushion and might be more comfortable. Nope. It's the same comfort level as different chairs. My reer still goes numb and gets uncomfortable in this chair. Also, where your arms sit, the chair arms are slightly curved upwards and it causes my chair to be unable to fit under my desk. If they weren't slightly curved, that wouldn't happen. It's just another chair, nothing spectacular.

Perfect for work
Color: Grey
Great quality office chair. Easy to put together as there is minimal assembly required with easy to follow instructions. The chair has many sitting options. Makes for a perfect chair to use all day long. Its an ergonomic chair that allows you to adjust tilt tension, arm rest height, chair height, and allows to actually move arm rest upward and out of the way. You can swivel and sway and roll around with ease. Perfect chair for sitting all day. The head rest provides great neck support and the padding is very comfortable and supportive. The wheels are strong and the entire chair is sturdy. Quality material, The cushion is made with memory foam as well as comfort foam. Such a quality chair. This is a great value for the money. I would recommend to anyone that sits for any period of time for work or otherwise .

Great chair for everyday use
I’m really happy with this ergonomic chair. It was easy to put together and feels very sturdy once assembled. The mesh back is breathable and keeps my back cool even after sitting for hours. The seat cushion is comfortable and supportive, and the armrests are positioned well for working at a desk. I also like how smoothly the wheels roll and how easy it is to adjust the height. For the price, the quality is honestly better than I expected. I’ve been using it every day for work and it makes long sitting sessions much more comfortable. Definitely a great value and I would recommend it.

Excellent quality, comfortable for 8+ hour days
Color: Grey, Color: Grey
Since the reviews here were so very helpful to me, I decided to leave my own after using this chair a couple days.
To summarize: Overall, I am thrilled with this chair and would recommend! I work remote, in a small apartment and this works well for both space saving and silence when rolling over hardwood floors all day. For more details, read on!
It came packaged very nicely, so everything was well protected during shipping. There are no written instructions and to be honest, I didn't even look for them. If you've put one together before, this is pretty standard. The "leather" (not genuine, but feels like it) is thick and seems it will be sturdy for a long time. The padding is exceptional and that's the main reason I needed a new chair, as mine (a 'basic' brand one, IYKYK) only lasted one year before it felt like sitting on a hard plastic seat. The height is adjustable to go up higher than most, so for once I didn't have to raise it all the way to feel comfy. The surprisingly great thing about it is the arms that flip up, so I can push it all the way under my desk. I live in a small apartment, so every bit of space saved is a bonus! Speaking of apartments, the wheels on this are whisper quiet and I'm more than certain the neighbor below me is thrilled to not hear my clunky wheels from the other chair anymore. I was hesitant to pay too much for an office chair, but given the price and the quality, I feel it was an excellent purchase.
A few items to note, if you have never put one together before: hand tighten the screws first! Don't put them on full force, until the pieces have been mostly assembled. This will help it not come out lopsided and the holes will be a little easier to line up. Watch the video, it will make the process a little easier (unlike what I did - put the arms on correctly, thought that looked wrong, then put them on backwards and lost my mind LOL). The video will also show how to recline the chair, if you like that (I do). It has a recline that's smooth as butter.

Very comfortable and safe chair
This executive desk chair is very convenient , for its 90° flip-up armrests can be easily pushed under the desk, perfect for home office. The rubber wheels roll smoothly and quietly on my carpet. It supports up to 275 pounds so it is safe to me . The height-adjustable back with 360° swivel makes me move freely . The curved, padded backrest provides relieve back pressure , also it is very easy to set up.
