Traxxas pro style ball differential

The xxx-nt and gt come with ball diffs, and yes they are worth it. The Pro Ball Diff has a weak diff screw that requires extra care when assembling so it won’t become over tightened, or you’ll risk snapping the screw. The xxx-nt diff has basically the same components as the Traxxas Pro Ball Diff. All of the parts in the Pro Ball Diff are replaceable. The Pro Ball Diff offers much better handling going into turns and if you plan on advancing to a full-fledged off-road race truck the Ball Diff is something that needs to be learned. Follow the instructions than come with Pro Ball Diff’s closely. Here are a few tips concerning the Pro Ball Diff:

  • Here is how to hook up the ball diff
  • Follow the instruction and put the diff together
  • Tighten it up until the thrust washers just start to crush
  • Install the ball diff
  • (It is easier for me to use the right wheel in the next steps but R or L will work)
  • Tighten the slipper nut all the way
  • Hold the right wheel in your right hand while holding the spur gear with your right thumb
  • Now try to turn the left rear wheel while spying the slipper
Теоретический расчет максимальной скорости Traxxas Nitro Rustler

Задался вопросом о макимально возможной скорости Traxxas Nitro Rustler.
Математический расчет дал следующие результаты:

Traxxas Silicone Shock Oil - Масло для амортизаторов

Traxxas does not list the weight of this oil, but it is believed to be approximately 30wt.
TRA1666 - This is the standard oil that is installed in many Traxxas vehicles from the factory.

Вязкость масла, которое Traxxas льет в амортизаторы почти всех своих моделей составляет приблизительно 30wt.


As for gearing, a smaller spur gear or larger cb will gear the truck higher (more top speed less acceleration) & a larger spur and/or smaller cb will gear the truck lower (more acceleration and less top speed)


Подбор дисков

Задние колеса - хабы 12мм
Передние колеса - подшипники 5x11

Для установки подойдут колеса от следующих моделей TRAXXAS:

  • Jato
  • Nitro Stampede
  • Nitro Sport

As for the wheels, I know you can get them for a nitro rusty but make sure you order the right ones. N rustys use 12mm hubs in the rear and 5x11 bearings in the front. It will take all the same wheels as the Jato, Nitro Stampede and Nitro Sport. They will say Nitro rear or Nitro front in the description. Just an idea for you, if you want to invest $20 - $40, you can use electric rusty a-arms, hub carriers and castor blocks. This will make the truck 3/4 inch wider for better handling and you will use 12 mm hubs front and back. Then you could use the same wheels all round and rotate them to prolong the life of the tire.
