Testimonial: If you have been driving your 2016 Tacoma with oversized tires, then you are probably disappointed with the new engine combo, but with proper gearing, they are actually very nice. Nitro gear recently fitted the first set to the XOVERLAND 2016 Tacoma, which is fully outfitted and includes an AT Overland Habitat (camper). Rachelle and Rhonda complained that the new truck was constantly shifting and burning through a ton of fuel, that it "just didn't feel right." Installing the new 4.88 ratio Nitro gears resulted in an immediate improvement in driveability and later a 3-4 mpg increase on their 10-hour drive home.
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.
Nitro Gear Package for 16+ Toyota Tacoma is one of Nitro’s biggest sellers because these trucks need to be regeared. The Tacoma has a very tall overdrive in 5th AND 6th gear to turn low RPMS. The new 3.5l V6 makes plenty of horsepower, but needs to reach its power band. Even with stock tires we have found the 6th gear is nearly useless, the gearing is so high that the transmission is constantly shifting. In a STOCK Tacoma Automatic 6th gear puts you at ~1500 RPM @ 60MPH. This simply does not work. You may not realize it, but you probably are hardly ever in 6th gear unless you are almost going downhill. By regearing, you can bring the motor back to the RPM it needs to be. This will improve Economy, Performance, and shifting. This is one of the most important modifications you can make to your late model Tacoma whether on a stock truck, or especially when running oversized tire. This is the only way to properly compensate for inadequate factory gearing and the increase in tire diameter. We often hear people are worried they will turn high rpm’s if they regear. This is simply not the case. Remember, the Auto trans has a double overdrive. See the below examples: Example Stock 2019 Tacoma TRD Offroad w/ Auto Trans:
3.91 & Stock Tire, ~1500 RPM @ 60 MPH, ~1750 RPM @ 70 MPH (NOT ENOUGH RPM!)
4.88 & Stock Tire, ~1950RPM @ 60 MPH, ~2200 RPM @ 70 MPH
33” 4.88, ~1750 RPM @ 60 MPH, ~2000 RPM @ 70 MPH)
33” 5.29, ~1900 RPM @ 60 MPH, ~2250 RPM @ 70 MPH)
*Manual trans RPM figures will be higher.
