Hot RacingSTFF257N OT 57t Mod 0.8 Steel Spur Gear Arrma 1:10 4x4 Blx 3S 4S

Can’t go wrong with the metal gear over the plastic ones they normally come with.If it wasn’t for a bearing failure. This piece would have held up like nothing ever happened. But sadly the bearing took this out along with the pinion gear as well. ( both hardened HR gears )Original bought over 2 years ago with heavy use under all terrains.As stated. You will need to use 4 clutch packs with this one. There are no cons or a pros in having all 4 in there. It’s just what it needs to fit / sit in place.

Haven’t had any stripping problems since I installed this on a arrma senton with 4s lipo

Just noticed that you ha e to add another clutch plate to the set. Was having a hard time getting together.

Got this for my big rock works great hot racing is the way to go

Doesn't fit a senton 550 mega slipper.very upset as i thought all arrma vehicles with this chassis used the same gears but apparently I was wrong and now I don't have a spur gear to install....It needs a new slipper plate and shaft and I can't find the right one anywhere so now I have a useless gear.

I love it works great and it's not plastic unlike armmas crap parts

Great gear, stands up to tons of abuse. Just make sure you have a good clutch setup and your will love it.
