Hybrid Bulks... Again

[lincpimp]

If you go to the buggy ratio diffs (43/13) you will have to go to a 26t pinion to retain the same overall gearing/speed that you have now.

Or go to a 62 spur and a 25t pinion. you need about 2.5:1 reduction on the primary (spur/pinion) gearset to get the same as what you have now with the traxxas diffs. Only thing I would consider is do you have enough clearance to fit that gear combo, will the motor adjust enough? You could also go down to the 58t jato spur and run a 23t pinion. Just divide the spur tooth count by 2.5 to get the pinion size you need.
