Great cheap upgrade..
Super quality and not too bad to fit.Super easy to control now on steep inclines, Nice and slow !Does make your Trx4m a bit noisier though.

2 years in, still recommend.
TL;DR Only one run, so far so good. Running brushless Furitek.Update March 2025. Almost 2 years on these gears and still working great. Still highly recommend this if you want to rock crawl. Too slow for trail or general purpose driving, but a must have if you’re looking for more torque and slow speed crawling. I’ve had no issues out of these gears (or anything on my 4M for that matter)Update: April 2024, 1 year later still runs like the day I installed. I don’t drive it every day but at least a couple times per week. Would buy again.Original review:Installed in my Bronco running bearing kit and the Furitek brushless motor/esc. Gears dropped right in no fitment issues. There has been a clicking ever since installing the new motor but the plastic crawler gears from Traxxas also made a clicking. So I just run it. Worth noting though. These gears appear to be nicely machined. If you’re into rock crawling with your TRX4m, I’d suggest this as your first upgrade along with bearings second. Those two upgrades even on the stock motor and electronics make it a whole new truck. The torque of the stock motor is actually pretty good with the crawl gears. I bought these injora gears because I thought that I had stripped the plastic ones causing them to click when driving, turns out these click too. The quality of injora parts is excellent. I’m also running their brass differential covers front and rear. So far these are a 5 star all day. If anything happens, I’ll update my review.

Fait le taf
Très bonne compatibilité. Mais le trx-4m est devenu beaucoup plus bruyant. C'est dommage.

Parfait pour crawling
4 étoiles, une en moins pour le bruit, car beaucoup plus bruyant que les pignons en plastique.Excellent pour le crawling,plus facile à contrôler en basse vitesse que les pignons de stock et plus de couple. Plus lent en vitesse de pointe. Donc pour le crawling : ok . ]our le trail : préférer un pignons de 16.

Gorgeous and Perfect Fit
I wanted to slow my stock TRX-4M a bit to enable better crawling speed and ordered these metal gears to replace the stock plastic ones. They fit perfectly and should last forever as they are metal and not plastic. The kit includes a metal 11T pinion, but there are no instructions in this kit and I wasn't able to get it to fit the stock motor. I ended up buying another 87T motor from another company that came with a brass 11T pinion, which means my transmission is all metal gears now. The kit also included some small decals which was nice. I recommend this item
