How Does Torsion Bar Suspension Work


Is torsion bar suspension good?

The main advantages of a torsion bar suspension are soft ride due to elasticity of the bar, durability, easy adjustability of ride height, and small profile along the width of the vehicle. A disadvantage is that torsion bars, unlike coil springs, usually cannot provide a progressive spring rate. via

Do torsion bars wear out?

Torsion bars are long metal springs that are used in low-cost car suspension. Torsion bar suspension is used because it is cheap and durable, but it can still go bad. Most often torsion bars are damaged through impacts on the undercarriage or through rust. via

What is the use of torsion bar suspension?

In automobiles a torsion bar is a long spring-steel element with one end held rigidly to the frame and the other end twisted by a lever connected to the axle. It thus provides a spring action for the vehicle. See also spring. via

How does a torsion bar absorb shock?

Torsion bars are a kind of suspension system. They minimize the force of bumps and holes in the road felt by the car's occupants. These bars do this by absorbing some of that force by moving with the bumps rather than acting in opposition to them. via

Will cranking torsion bars hurt?

As long as you get the alignment, you should be fine. Your ride quality will be a little diminished, due to a stiffer front end. It's up to you, let us know how it goes. via

What happens if torsion bar breaks?

Subject: Re: what happens when you break a torsion bar? Highly unlikely you break 2 bars at once. Unless someone has hacked them up with vice-grips at one time perhaps. When one breaks you will a loud bang and the left or right front will sit very low and ride on the bumpstops. via

Are torsion bars better than coils?

Apart from packaging considerations, torsion bars do have one glaring advantage over coil springs. The down side is that raising a vehicle with torsion bars will not increase the suspension's range of motion, and that preloading it in such a way may shorten its lifespan. via

Do you need new torsion bars?

Generally speaking they are not considered a wear item like brakes or tires. But they are just like any other spring, they will settle and can wear over time. I have even seen them break a few times. It may be that yours are worn out and need replaced, but I would try adjusting them up first. via

Do torsion bars need to be adjusted?

Adjust the torsion bar. Turning the adjustment bolt clockwise will tighten it, raising the amount of load that can be placed on the bar. This will raise the vehicle when it is taken off the jack stand. If they are not, then more adjustment will be necessary to the torsion bar adjustment bolts. via

What is the difference between a sway bar and a torsion bar?

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. via

How do I know if I have torsion bar suspension?

The bars run from the front a-arms to under back of transmission. If its 2wd you have coil over shocks, if it's 4wd you have torsion bars. via

What are signs of bad suspension?

Suspension Warning Signs

  • Continued bouncing after hitting bumps or a dipping when braking.
  • A drifting or pulling to one side when turning corners.
  • One side of the parked car sitting lower than the other side.
  • Difficult steering.
  • Unusually bumpy rides.
  • via

    Is torsion beam suspension bad?

    While the torsion beam or “twist beam” isn't as compromised as a solid axle, neither is it a truly independent suspension. Stiffer bushings can compensate for the torsion beam's inherent side-to-side compliance, but that comes with a toll of greater impact harshness. via

    Do torsion bars affect ride height?

    There are several factors involved in adjusting the ride height of a vehicle with torsion bar suspension. The angle of the control arm and the amount of torque or twisting motion applied to the torsion bar. On some vehicles, the CV joints can wear prematurely if the ride height is over adjusted. via

    Is it bad to crank your torsion keys?

    Most mechanics don't recommend cranking on the torsion bars, as it's hard on the alignment. I put keys on my '07 2500 HD & lifted it about 2", then aligned it. It wasn't off by much, but enough to wear your tires in time, especially if you don't rotate your tires. via

    How far can you tighten torsion bars?

    You can go as high as long as you maintain at least 5/8's of a inch between the UCA and frame stop and that also includes needing to fix the OE shock due to being to short. Either a lower mount or longer shock. via

    Can you install torsion keys wrong?

    Re: Torsion Keys

    Yes,if the keys would be installed wrong,it would be almost impossible to install. via

    Is it safe to drive with a broken torsion bar?

    If you suspect that a sway bar is broken, you can still drive the car, but you must use caution. It will feel “looser”, particularly when driving at high speeds. It's very possible that this will cause you to lose control of the car, resulting in a serious accident if you're not prepared for it. via

    Do Mopar torsion bars wear out?

    Torsion bars count on the modulus of elasticity of the steel they're made of. As long as the modulus of elasticity is not exceeded the bars should never wear out! via

    Do torsion keys make your truck ride rough?

    Re: Replace torsion keys or turn up keys??

    More preload on the torsion bars = rough ride. It's very simple if you think about it. All you're doing with the "leveling keys" is twisting the torsion bars more. You can also go too far and you'll be hitting the bump stops. via

    What year did Chevy stop using torsion bars?

    The torsion bar front suspension would never return to light-duty GM two-wheel-drive trucks, which use coil springs to this day. (The torsion bars added to GM light-duty four-wheel drive trucks in 1988 were dropped beginning with the 2007 model year.) via

    Can you put torsion keys on a 2wd?

    Everything suspension wise is interchangeable between the two, this means you can use the same method of cranking bars on a 2wd as a 4wd, and the same leveling keys that work on a 4wd work on a 2wd. So yes the 2003 3500 2wd has torsion bars that you can crank just the same as a 4wd. via

    What forces act on a coil spring?

    A coil spring is a mechanical device which is typically used to store energy and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces. Under tension or compression, the material (wire) of a coil spring undergoes torsion. via

    How do you release torsion bar tension?

    It is recommended to lift the front end to reduce stress on the threads as you turn the adjuster bolt. I always spray some penetrating fluid on the bolt to help with the years of crud and rust. Then counterclockwise relieves the tension on the bar. via

    Can you lift a torsion bar suspension?

    Because as i have said before and you know this but most 4x4 owners do not is a torsion bar does not lift a vehicle at all stiff or standard a torsion bar has nothing to do what so ever with lift or ride hieght. via

    Is there a left and right torsion bar?

    Yep, it matters. The odd numbered bar is the left (drivers side) and the even numbered bar is the right (passenger side). via

    Can you adjust torsion bars on the ground?

    You can lower it if you like when it is on the ground. There is more pressure on the adjuster bolts, the higher up the control arms are, but it doesn't really make a difference to lower. via

    How do you adjust torsion bars evenly?

    Work the wrench in a circle, turning it the same number of times that you turned the bolt on the other side of the vehicle. Make sure to turn the bolt the same way on this side—clockwise to raise the vehicle or counterclockwise to lower it. via

    How does a rear sway bar affect handling?

    Basically sway bars reduce roll and dramatically improve handling. They connect one side of the suspension to the other with attachment points generally on the lower A-arms and frame (chassis), and twist to limit the roll during cornering. As the truck enters a corner, centrifugal forces create a body roll force. via

    How does a rear anti roll bar work?

    What is an anti-roll bar? By connecting both ends, the anti-roll bar forces both ends of the axle – the wheels in this case – to raise or lower to a similar height, preventing roll. The bar resists twisting, or torsion, through its torsional rigidity. The stiffer the bar, the less the car leans in turns. via

    What does the front sway bar link do?

    Sway bar links are what connect the outer end of the sway bar to the suspension component. Because the sway bar itself is a torsional swing, the sway bar link smooths the motion transfer between the sway bar and the control arm. The sway bar link maintains the camber angle of the inner wheels to control motion. via
