Toyota 8.75 Inch 4.88 Ratio 16-18 Toyota Tundra Ring And Pinion Nitro Gear and Axle


Nitro Gear and Axle strives to provide the highest quality differential components available. We take the steps necessary to ensure our parts are dependable. Our product range is continually growing to meet the needs of consumers for new ratios and applications. At Nitro we know differentials, and know what it takes to provide you with high quality components. Nitro gears are manufactured from 8620 steel gear forgings in the same manufacturing facilities as GM, Dodge, Ford and Toyota. They are precision machined using computer controlled processes, heat treated, CNC triple-lapped and Rockwell tested for hardness. These extra steps ensure excellent fitment, ideal contact pattern and smooth, quiet operation.

  • 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 stet to the XOVERLAND.COM 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 did not 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. You can see the video from the shop floor at the Expedition Overland facebook page.
