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.

Power Chewer Loves This!
Size: Medium, Color: Antler
This is my dog's new favorite chew! She loves that she can hold it in her paws. I think she really loves the taste and texture of it. I don't give her antlers as I have heard too many horror stories about broken teeth. I also don't give her nylon toys as I have also heard a lot of horror stories of broken teeth as well as concerns about them digesting the plastic. This is between antlers and bully sticks, which is perfect for a power chewer. I feel comfortable with her eating the pieces that flake off this toy. She loves chewing and she will default to this toy when she wants to help calm down. I don't notice much of a smell. It does flake, but not enough I will even take a star off. Plus, it's plant based and vacuums up easily once dried. It doesn't capture her attention as much as bully sticks or beef cheek chews, but it's much less expensive over time and doesn't stink up our living room! She will also always pick this over any of her rubber chews. Great product and recommend it for all the power chewers.

Crumbly, odd texture
Size: Large, Color: Duo Pack
Neither of my dogs were very interested in these. They did chew on the antler-shaped versions more so than the infinity-style versions. When they did chew on these, they didn’t hold up well or last long. These have a strange, crumbly texture when chewed. You’ll find bits and pieces of these chews where the dogs have been chewing. Will not be reordering.

This appears to be a good alternative to the hard plastic chew toys.
Size: Large, Color: Duo Pack
My dog is a heavy chewer. I decided to try this brand out after using a different brand for quite awhile. while my dog seems to like it and carries it around (the pretzel shaped one) he doesn't seem to attack it as whole heartedly as his old brand, I'm thinking it might be the shape, we will see when he wears it out and I switch him to the antler shape. What I like most about it is it doesn't tear my hand up like the other brand did after he had been chewing it for awhile. While it is wearing down some it seems to do it in a more mild manner. Since we haven't had it long I would give this 3.5 stars because I don't know if it will last as long and not sure f it is just the shape that has him more mellow with it.

Choose your shape
Size: Medium, Color: Duo Pack
I love the idea of the dogs not eating nylabone plastic so have been searching for "healthier" options that last for heavy chewers. Two German Sherpherds, they are not big fans of the circular shaped toy but love the antler shaped one and even with both chewing on it, has not been destroyed yet and is not cutting their gums open. I am not finding pieces laying in the carpet. Recommend this
