Ultralite 7.5-8 spider diff set:got some questions

[George16]

Vis-a-vis, the 8 spyders are stronger than the regular 6. However, once you replaced the regular 6 with the HB hardened gears or the Ofna Violator hardened gears, the 6 will be stronger. The plastic cup allows for flex and this is what destroys the internals. The metal cups will definitely make a huge difference. I have the 8 spyders with metal cups in my Gmaxx.
