diff cases and cups

[jhautz]

Kind of related to this... Has anyone tried the RR Revo diff gears? Are they better than the stockers? I am rebilding my diffs. I blew out the rear last time I ran. I ran the 9XL on 6s Lipo and it didn't take long to blow the rear diff.(blew the side of the diff cup out) I'm going w aluminum cases, cups and am thinking about getting the RR gears. Are the RR gears worth the $40 a set, or am I just wasting $80 to do both sets. Will the alloy cups and cases be enough with stock gears if I shim them properly? Or are threr any other diff gear solutions that Im not considering?
