Not possible....The Hybrids are for 1/8th scale gears. So that would require HB diffs, Ofna diffs, Kyosho diffs, UE diffs, etc. FLM doesn't make 1/8th diffs. They make stock replacements with would require the Combo bulks, not Hybrids.
sorry my mistake squeeforever i ment the combo(the combo still is the diff build into the bulk right). What lubricant if any should i use for my gears. and will they hold up to a 4.5 HV.
