UE Ultralights

[suicideneil]

Based on my latest findings & discussions, it seems like the Hyper 9 diffs are slightly different to all the others ( 6/7/8 etc ), or atleast they have different part numbers for the ring & pinion gears; you are better off staying with the earlier models or Hotbodies lightning buggy diffs, to be 100% certain they will fit the UE diffs and VBS bulks. UE drive cups should work, given that their diffs are actually just Ofna Spider diffs regardless.
