Helical cut or Straight cut Diff Gears?

[STINKYBOY13]

OK XTM Mammoth with too much slop in the diffs. I am going through pretty much everything and the diffs are pretty shot. Also converting it to BL.With things I had layin around MM,4s lipo,feigao, ect. Just don't want to mess with it when I,m finished. Unless I break it. Thanks

Well if you can get either then Helical is typically smoother and possibly a little stronger. The only real thing to worry about is what the gearing is. Typically the truggies run the lower ratio diffs with helical cut and the buggies have a higher gear ratio whit straight gears.
