Nitro Gear packages for your vehicle, now with 1 part number!

Nitro Gear and Axle has led the way for many innovating R&P and axle packages. Now they have simplified the way you purchase gears. With one part number you can purchase your front and rear ring and pinions, master install kits, solid preload spacers, and new yokes if they are required. No more searching around to find the correct install kits and ratios for both your axles!

Do you really need new gears in your axles?

It is a common misconception that Re-Gearing a vehicle is only for Hardcore Off-roaders or for huge oversized tires. In fact, most of the late model vehicles we produce aftermarket ratio’s for are daily driven vehicles with slightly oversized tires. In an effort to improve fuel economy, Late model overdrive transmissions are geared very high which means RPM’s are very low on the highway. When even a slightly taller tire is installed the RPM’s are reduced below acceptable levels that the engine was designed to run. This causes constant shifting out of overdrive, sluggish acceleration, poor economy and rapid wear on the transmission and other components.

By changing the Ring & Pinions in your vehicles differentials, you can match the ratio to the tire size to bring the RPM’s back to where the manufacturer intended. Typically it is recommended to select a ratio slightly lower (higher numerically) than what the math will tell you. This will help accommodate increased rolling resistance, wind drag, and added weight of aftermarket accessories and gear.

It is a common misconception that lower gears are only for hardcore off-roading, in actuality the average daily driven vehicle can see huge improvements in both performance and economy by properly matching their vehicle’s gear ratio to their tire size all while reducing strain on the vehicles drivetrain.

We at Nitro Gear & Axle realize how confusing and difficult it can be for the average consumer or gear installation shop to compile the list of gear parts and prices required when doing a complete front and rear gear change. To make it easier for everyone the experts at Nitro Gear & Axle are introducing an industry first - "Gear Packages"

These gear packages are specifically designed for many popular 4x4 applications such as the Dodge Ram, Chevy/GMC 2500/3500HD, Toyota Land Cruiser/FJ Cruiser/4-Runner/Tacoma/Tundra, Jeep Cherokee/Wrangler/Rubicon and Ford F250/F350 Super Duty.

These gears are manufactured from 8620 steel forgings and are precision machined using a computer controlled process. Heat treatment, CNC triple-lapping and Rockwell testing for hardness ensures excellent fitment, ideal contact pattern and smooth, quiet operation.

Nitro Gear & Axle sells ring and pinions for more than just the Dodge, Chevy/GMC, Toyota, Jeep and Ford vehicles listed in our gear package section so please contact us if you don't see your vehicle listed in our gear packages.
 
Congratulations to Jessi Combs and Nicole Pitell-Vaughan for successfully completing the Rallye Aïcha des Gazelles in their Total Chaos Fabrication Inc. built Tacoma. This truck is running NITRO gears among many other upgrades. We would also like to congratulate our friends Ronda Rhonda Cahill & Rachelle Croft of Expedition Overland on also completing the challenge.

If you are looking of the strongest ring and pinions to stand up to all the abuse you put your rig through, check out NITRO Gears!

 
Overlanding.

I don't need to regear, my tires are only a little bigger than stock.

It's a common statement and one we enjoy addressing when the opportunity presents itself. Overland preparation tends to add weight to the base vehicle. Bumpers, winches, skidplates and tire carriers can add a tremendous amount of weight from stock. Add a rooftop tent or rack assembly up high and aerodynamic drag is greatly increased as well further reducing performance both on and off-road.

Beyond increased weight, vehicle manufacturers almost always opt for a borderline gear ratio from the factory to optimize unloaded fuel economy. This means that even running near stock size tires, a heavily loaded, taller than stock and factory undergeared Overland 4x4 is a very poor performing machine both in terms of acceleration and fuel economy. This reduces cross country fuel range, on road responsiveness and off-road control all at the same time.

The solution is regearing. Proper gear ratios put the engine at optimum RPM for performance and fuel economy and give you the opportunity to add traction aiding differentials during gear installation greatly enhancing the capability of your backcountry 4x4 in the field, on the highway and around town.

Just Differentials is the leader with gear packages available for all the common Overlanding platforms. These kits include ring and pinions, full master setup parts and everything your mechanic needs to regear your rig and make it function as it should instead of gasping every time you climb a mild grade.

Building a sweet 9 inch assembly in the shop this week. Nitro Nodular housing, Nitro LSD unit, Nitro 1350 forged yoke and a REM treated 3.50 Nitro Gear Set. REM treating produces an incredibly smooth surface finish for reduced noise, cooler running and longer lasting gears. Ideal for keeping gear noise to a minimum and an option on some Nitro gearsets.

We can build one for you as well, or just about anything else for your axles. Call 866-349-6801 or click on the link below to see all our gear and axle options:
