The Strongest Savage Diff Compilation.

[JasonB]

They designed the HPI aluminum cup to accept the 10x16 for a reason. The HPI ring gear uses the 8x16 because it is steel, not aluminum. The only way to build a strong aluminum cup for the savage is to put a steel end cap on it, IMO. Can someone please prove me wrong . . . I would love to be wrong on this one.

What size bearing did the cup in your Losi use? If it was an 8x16, then my guess is the diff shaft was smaller in diameter to allow for a thicker wall on the cup. Just a wild guess here because I've never owned a Losi.
