  • Easy kit for for beginners that feel adventurous!
Pretty amazing upgrade for an older brushed Senton beginners truck. Was very easy to install and speeds are insane with the 3s battery. Works very well with 2s 5000 if you want better lower speed control

  • Insane
If you are looking for an insane upgrade this is it right here. I got this for my arrma senton, and it was basically plug n play. Install took about an hour and fit very nicely. I paired mine with ovonic 3s lipo battery and the run time is impressive. I would recomend getting the electroncs cover, because small rocks can get into the cooling fans very easy.very good quality parts and durable . ... show more

  • Works great!!
I had a stock Granite 4 x 4. This kit just screwed on very simple and now the truck is a monster. Almost too fast for its own good. Lol. The instructions were not exactly step-by-step, but they were close enough to figure out.

  • Powerful!
Almost too much power for an ARRMA Granite. Really fast. Unfortunately, my receiver quit, so can't speak to longevity.

  • I like it so far
Easy to install! Worth the value for all the parts you get with it. Seems to work well

  • Received open box, missing components.
Great motor and esc upgrade. Unfortunately, this one I received was an open box missing hardware and the additional spur gears.
Reviewed in the United States on March 3, 2025 by Tires do not come glued, and they are to loose on the rim to glue them down. Do not recommend.

  • Granite 4x4 3s Power
You should definitely get a wheelie bar with this... took my Granite 4x4 Mega to a whole new level. I like that it comes completely assembled and its easy to install, plus tons of step by step installation videos online... also would recommend upgrading the motor mount that comes installed with this, the factory mount tends to bend on hard landings. I upgraded mine to the blue mount in the pictures ... show more
