Modified big rock v3 4s

Installed this set with input gear and composite housing. So far so good! 4s cars should have came factory with this setup! Adding it to 3s line makes them nearly indestructible. I run a hobbywing max10 sct on my big rock 4s! No more stripped diff gears! Highly recommended. I also added the steel Arrma spur. Yes it is a bit louder but the strength is more important! Used the factory shim that came with composite gears and it meshed perfectly!

Best upgrade for 4x4 blx series.

I purchased this, the diff case, and cnc input gear. Much better than the cheap plastic diff. It's basically indestructible now. Must have if you plan to run 3s/4s all the time. You can really go for a rip without worrying.
