The 4 bevels in alu cup are pretty indestructible but the ring and pinion can still slip with the flex in the diff casing under extreme load. I'm not saying you will break them straight away they are fairly bullet proof. Just check for slop in the diff and add shims if necessary. Also check the diff bearings as they go eventually and will cause the ring and pinion to die. I had a diff bearing go and the ring and pinion still look perfect even though they would of been slipping like crazy.

If you want to build an electric savage there is a shop called nitronutzz on ebay which chops xss savages. I bought all the stock parts I wanted for under $120 dollars I think. This included tranny, diffs, bulkheads, screws, dog bones, turn buckles and just about everything bar nitro gear, tvp, shocks (i use the LSTs) and radio box. I just need the FLM forward tranny chassis though.
