Revo set back arms

[coolhandcountry]

It is taking less punishment in the center. It is only taking the torque of the motor times the ratio of tranny and spur pinion. while the rears take the punishment of that times the diffs. if the motor puts out 20oz of torque with a 1.72 tranny and a 3.2 spur pinion ratio. the center diffwould only have 110.8 oz of torque applied. If you figure the diffs would have another 3.31 on top of that 366ozs of torque on them. Hope this helps.
