Well, there is a steel/aluminum differential gear, hardened steel idler and aluminum transmission case available for my truck here in the RC Monster store, but they cost a fortune. I have, however, considered getting them on a few occasions. My only worry is that they don't hold up to their hype. It would be a shame to spend $150 plus on them and have them still fail.

Has anyone had any experience running them in a Rusty or Pede? Will they make the trans practically bulletproof?
