Yea as some others have found out steel on aluminum and aluminum on aluminum dont work for long. To be honest I have used the stock plastic gear on multiple high speed passes in an a heavy all aluminum truck a with no failures. I think the biggest issue is the slipper needs to be adjusted properly to prevent failure a strobe slipper helps also. Those steel gears are awesome but I wonder if the power loss from the additional rotational mass probably works out to be the same as a slightly slipping slipper. Is that a still a 2 speed tranny ?
