Great upgrade for the non-brushless version or replacement for the brushless version. Make sure to disassemble the driveshaft cups and locktite them with blue locktite. It took about 5 days of hard running before mine and my 4 buddies all had ours come loose at almost the exact same time on our Mojave brushless Groms. Locktite should solve the issue.

You’ll bust your stock one when going brushless.

I got this for my brushless typhon grom, and it's awesome. Since it is filled with silicone oil, it will last much longer, and my grom seems to handle better. The best thing is that I don't need to worry about plastic outdrives or gears stripping since it's all metal. It's a bit expensive, but it will last, which is important.
