Suffering from poor performance and reduced fuel economy resulting from over-sized tires?

The new Ford Bronco is arguably one of the best out-of-the-box offroad vehicles on the market. Its 35" tires and stock gears keep the engine and transmission turning at just the right speed....almost. Adding 37" tires, most people recognize the constant shifting of the transmission as it 'hunts' for a gear that works best with those larger tires. Our tests on our Bronco Badlands Sasquatch edition with 37 inch tires, ran a little low in the RPMs, lugging that engine and transmission. This happens 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 drive-train.

Re-gearing our test Bronco to 5.29 ratio gearing with 37 inch tires, brought the RPMs up to a perfect 2000 at 60mph, giving the ideal shift points in the power band, resulting in more power and better fuel efficiency.

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.
