Hardened steel Stampede/Rustler idler gear Question...
 

Do the gear teeth on the new idler go all the way to the edge of the gear to cover more of the stock differentials gear teeth or is it identical to the aluminum idler which only covers about 4/5ths of the stock differentials gear width? I think if the idlers teeth were as wide as the diffs teeth it would help reduce stripping the diff a little bit better.

The hardened pede/rusty idler is the same dimensions as the stock idler and aluminum Traxxas idler. The aluminum idler gets sharp from running against the steel input gear, which leads to stripping the diff gear. The hardened idler will be the strongest tranny component and won't sharpen itself against the input gear, so the stock diff gear will last a lot longer. We also carry a steel/aluminum diff gear for those looking to run high HP through these little trucks. The aluminum tranny case also minimizes flex inside the tranny, which again allows the gear mesh to stay constant and minimizes any potential stripped gears. :)

Another great job by RCM!
