    Is a smaller pinion gear necessary with the 3.8" Mud Slingers?

    Again, very new to this. My Mud Slingers(3.8") finally came in and I remember reading in the manual that if you increase the tire size, you have to use a smaller pinion gear. Is this really necessary to avoid being too hard on my all stock truck?
    (I am planning on shimming the diffs)

    Your stock power plant will definitely benefit from a smaller pinion.

    Larger pinion = Less*torque*at the*wheels, more top speed (up to a point before it's too large), less acceleration, more stress on motor and heat.

    Smaller pinion = More*torque, slower top speed, better acceleration, consequently better runtime, less heat and stress on motor.
