### ⭐⭐⭐⭐⭐ Review
*by D***E on 26 April 2023*

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.
