Sway Bars vs. Torsion Bars???


Well-Known Member
Don't sway bars and torsion bars essentially do the same thing???

I know what sway bars do and how they work, but I've never messed with a vehicle that has torsion bars so I'm completely unfamiliar with them and have never taken the time to read up on them. . .are these just different names for the same thing in different vehicles?

Not the same, torsion bars are the spring that holds up the vehicle. Chevy 4wd ifs trucks have used them since 88.

Yeah they do the same thing. They are both springs. The sway bar is a torsional spring that only works when you have side to side weight differentials. They do the same thing, just at different times.

torsion bars support the weight of the vehicle like the coil spring on a coil-over. Sway bars don't support the weight but instead are a connecting link between the two sides of the suspension on a vehicle...so if the left side compresses the sway bar will try to compress the right side at the same time....i think that made sense.....
