Review: Works great - If u buy this for the redcat volcano epx just be prepared that it makes it react like a hole different truck just because of the weight of the rotating mass
Review: Good upgrade. - Red Cat Lighting. Replaced original gears with this set Spur 64/ 21 Pinion. I installed with Traxxas VXL motor and esc. Speed is good sounds great and the gears are holding up on 3S. I would like MOD 1 gears.

### ⭐⭐⭐⭐⭐ Good upgrade.
*by R***N on August 24, 2018*

Red Cat Lighting. Replaced original gears with this set Spur 64/ 21 Pinion. I installed with Traxxas VXL motor and esc. Speed is good sounds great and the gears are holding up on 3S. I would like MOD 1 gears.

### ⭐ Downgrade part! Didn't get 20 ft before pinion was completely round. Teeth just broke off.
*by L***N on January 23, 2020*

Sheared off every tooth the moment I hit the throttle on a 1/18 A959 running a Surpass Platnium brushless 5900kv motor on a 2S battery so it definitely won't handle bigger cars. Just like the other 90% of RC parts I've bought on Amazon these are crap downgrade parts. The original cheap brass pinion has barely worn down. I ordered these to change gears & just threw $ away. Seems like I have to blow $100 on trash to find a $10 part up to OE standard. Bought new axles, 1 broke immediately, new gears, 1 went immediately, new wheels & tires that wont work on my car. All I got for $60 is more repairs & headaches
