Looks good machining mechanical foremost, quality nice.
Fit well performed as expected, good price
I have different combinations on different vehicles, some get overdriven up front for more speed, some get underdriven rears for better slow crawling, I usually put a 2 tooth difference between front and rear. Well made gears, the axle doesn't strip out the gears under heavy torque like brass gears. These are a great way to fine tune performance and work in stock SCX24, Injora planet and RCAWD portal axles with no problems. Grease 'em up really good on installation.
Excellent products, great quality!
Perfect amount of overdrive fit nice
This makes such a difference on the climbs. It pulls from the front but not in an awkward way. It steers better and is an improvement in every way.
Fit perfect no issues
At first I got the overdrive but then I realized I wanted more torque so I went with the underdrive
Very well built
Underdrive 12t provides a nice clean mod to increase your low end torque so the stock motor does not need to struggle. Yes, your top speed is reduced accordingly, but this is for crawling. One set includes gears for the front and rear.
Bought cheap from ebay originally and regretted it. Had insane binding issues.
Bought these instead and they are perfect. Much better than stock and a nice upgrade to help you climb up things.
10/10 recommend
My little SCX24 Bronco climbs like a champ with overdrive. Worth a try!
Perfect
Nice
Easy to assemble (watch the videos on youtube), it's one of the mods that changes the car the most: it climbs much better! Very satisfied!
the underdrive is awesome if you want to crawl slow, even with stock motor
Great build quality and performance to match
Plug and play, fits like glove. No brainer. Get it :)
Here is a little help which one to choose for what. https://youtu.be/iXTsDkc5BEU
The 14t made a very noticeable improvement in my climbing and even turning radius, along with bearings and some grease this should be the first upgrade anyone considers
super nice!
Will these gears work with the Planet axles?
Yes.
Do these fit stock axles
Yes.
