The 2016 & Newer Tacoma is a fantastic vehicle, the new engine packs a punch into a fairly small displacement, and needs RPM's to operate efficiently and at peak performance. We have found the factory gearing to be inadequate even on stock vehicles in many cases. By re-gearing your diffs with a Nitro Gear Package you can restore performance and economy by optimizing the RPM range your engine runs at. We've already provided gears for hundreds of 2016+ Tacoma, with excellent feedback and reports of much better drivability, performance, and economy. Many say that they love that their truck is not constantly shifting, and just feels “right".
Here are some rough recommendations based on tire sizes for the average daily driver/weekend warrior:
34" or larger 5.29 (Great for especially loaded trucks, or towing. Also ideal for 4 cylinder trucks)
Nitro Gear Package for 16+ Toyota Tacoma is one of Nitro’s biggest sellers. Why? 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.
Testimonial: If you have been driving your 2016 Tacoma with oversized tires, than you are probably disappointed with the new engine combo, but with proper gearing they are actually very nice. We 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 drive-ability and later a 3-4 mpg increase on their 10-hour drive home.
