why do 4x4's have torsion bars?
 

hey guys,

anybody know why?

thanks

Robert

Tried and true. Torsion bars are compact, leaving more room for driveline components.

Easier to adjust and replace.

Cheap. Hard to break.

BTW I think torsion bars have also been used in some cars (I don't know which ones) as well as tanks.

They used them on my 92 Nissan 4x2.
I liked them https://www.f150online.com/f150board/smile.gif

thanks guys. I was wondering because I know 4x2 f150's do not. Also I had an idea of using airbags to elevate the truck but when parked or in parking structures, you can lower it to fit

The reason is because when you put a drive shaft between the two front suspension "A" arms in order to drive the front axles and wheels on a 4X4 there is no room left for a coil spring. Thererfore you need a torsion bar to provide spring to the front end. Torsion bars act as the front springs or coils for a 4X4.
