well. the wide tires only account for about 1-1 1/2" wider stance. the MAIN width extension does come from the control arms being wider. which allows for great up and down travel without affecting (effecting?) suspension geometry.

it also allows for those nice 60+ mph woop turns and jump without feeling anything inside the cab

4wd would be the same parts. but you would have to figure out how to get wider axles... alot of trophy trucks and prerunners are 2wd becuase they just lay the hammer down and hold on.

 

So with the kit you would need new axles?

 

if youre 4wd you would need longer front axles. 2wd is unaffected
