Is there anyway to get lower gearing on a scrambler 500 HO 4x4? I would like to change the wheel and tire size to 25” & 26” but I will need lower gearing for the tight, rocky and steep hill riding I do. The only way I see to do this is to change the gears in the gear box but I have no idea if they make different gears that will work for this or not. Has anyone done this before?
