Sure, although dont forget that the wheel shaft has a larger diameter with a larger wheel with a different offset. If you changed those parts you have to change many other things. Not to say thats inpossible but it would nto really be worth it and it would be cheaper and easier just to buy a second hand Savage and change the motor....?

Here is a picture of the MT arms with a Savage arm. I am sure it could be done but not very easy. All so keep in mind the higher the vehicle the easier it will roll over.
