    Default what is the advantage of a higher gear ratio for a TRX4 Sport [79:1]

    Hi I am looking to go for the higher [bigger] gear ratio more to the 79:1 end with my TRX 4 Sport. [9t pinion to 45t spur]
    Just would like to know
    1. Is there any real advantage?
    2. What is the highest number of turns of a 550 size motor is a 45t to much?
    3. How can I be able to go over pretty much anything in my way. Open to other options – set ups

    1. More torque. But you'll lose overall wheel speed. Add more volts to gain it back.
    2. Highest is relative. I wouldn't go with any less turns than 30 in a traditional motor, 16 in a 5 slot.
    3. Practice driving.

    thanks for the advice - what gear ratio do you aim for?

    Somewhere between 36:1 and 50:1.

    higher gear ratio is harder on the drive line and motor (because the motor needs to work harder to make the truck go) but it might help in mud bogs

    when mudding you don't want weight but with regular crawling you want very low down weight, a mod that is bad for the truck but increases performance is front overdrive and low down weights
