Larger tires often lead to a loss in performance, fuel efficiency, and constant transmission gear "hunting" due to a shift in the engine's optimal RPM range. The Nitro Gear Package Kit addresses this issue by allowing you to re-gear the differentials in your 2007-2021 Toyota Tundra, bringing it back into its optimal operating RPM range. This not only improves performance but also reduces strain on your vehicle's drivetrain, especially crucial for modern vehicles with tall factory gearing and overdrive transmissions.
Contrary to popular belief, re-gearing is not limited to hardcore off-roaders. It is one of the most beneficial modifications for daily-driven 4x4s with larger tires, increased weight, or those seeking enhanced performance for towing or acceleration. The Nitro Gear Package for 07+ Tundra is a top choice, addressing the unique needs of these trucks. The Tundra's tall overdrive in 5th and 6th gears can become inefficient with 33" or larger tires, resulting in poor economy, constant shifting, and decreased acceleration. The gear ratios of 4.88 or 5.29 are specifically tailored to accommodate different tire sizes, ensuring optimal RPM at various speeds. It is recommended that 4.88 gears be used with 33", and 5.29 gears be used with 35" and 37".
In addition to performance gains, the Nitro Gear Package also addresses traction issues common in 07+ Tundras. The factory "Electronic LSD" is more traction control than a true Limited Slip Differential (LSD). Upgrade your Tundra's traction with an aftermarket LSD or Locker for increased off-road capability and strength. The Nitro Gear & Axle experts have simplified the gear change process by introducing industry-first "Gear Packages" – one part number, one price, one click away. Ensure a smooth installation by using 80W-140 gear oil (6 quarts required) and experience the transformative benefits of Nitro Gear & Axles Gear Package Kit on your Toyota Tundra.
