What does turning up torsion bars do?
Turning up torsion bars is a suspension modification that can raise the ride height of a vehicle. This adjustment is often done to improve off-road capability, increase ground clearance, or achieve a more aggressive stance. By understanding the purpose and effects of adjusting torsion bars, vehicle owners can make informed decisions about modifying their suspension.
What Are Torsion Bars?
Torsion bars are a type of suspension component found in many vehicles, particularly trucks and SUVs. They consist of a steel bar that is anchored at one end to the vehicle's frame and at the other end to the control arm or suspension link. When the suspension compresses, the torsion bar twists, providing a spring-like force that helps support the vehicle's weight and absorb impacts.
Adjusting Torsion Bars
Turning up torsion bars refers to the process of increasing the pre-load on the torsion bars, which in turn raises the vehicle's ride height. This is typically done by turning the torsion bar adjustment bolt, which is located on the frame of the vehicle. By turning the bolt clockwise, the torsion bar is twisted more, resulting in a higher ride height.
Benefits and Drawbacks of Turning Up Torsion Bars
The primary benefit of turning up torsion bars is increased ground clearance, which can be beneficial for off-road driving or navigating obstacles. This modification can also give the vehicle a more aggressive, lifted appearance. However, there are some potential drawbacks to consider:
- Ride Quality: Increasing the pre-load on the torsion bars can result in a stiffer, less comfortable ride, especially on rough roads.
- Handling: The higher ride height can affect the vehicle's center of gravity and handling characteristics, potentially making it less stable and responsive at high speeds or during sharp turns.
- Tire Wear: The increased ride height may cause the tires to wear unevenly, leading to premature tire replacement.
- Suspension Geometry: Adjusting the torsion bars can alter the suspension geometry, which may require other modifications to maintain proper alignment and suspension performance.
It's important to note that the specific effects of turning up torsion bars can vary depending on the make, model, and year of the vehicle, as well as the extent of the adjustment. Consulting a professional mechanic or suspension specialist is recommended to ensure the modifications are done safely and effectively.
How much does adjusting torsion bars affect alignment?
Depends on the amount of cranks you lower it. If it's a good amount, it will probably cause negative camber on both tires. Wouldn't hurt to get it aligned, but it's ultimately dependent upon the amount you drop it. Good call on relieving some of the stress on the torsion bar.
Which is better leaf spring or torsion bar?
Torsion trailer axles offer a smoother ride and less maintenance. Leaf springs are more durable, less expensive and far easier to replace parts on. Selecting the proper axle is as simple as determining your application, and figuring out the loads you need to carry.
What does raising torsion bars do?
Here are the general steps to adjust a torsion bar upwards:
This will increase the amount of torsion on the torsion bar, which will lift the vehicle's front end.
What should I adjust for alignment?
Alignment is accomplished by adjusting four specific suspension angles—toe, thrust, camber, and caster back to their factory settings. These angles are adjusted by a trained technician using some complex, and expensive machinery, so it's unlikely you'll ever find yourself performing your own alignment.
What are the pros and cons of torsion bar suspension?
Due to their small size, tremendous load capacity, and relative ease of service, torsion bar suspension has been ideal for tanks, though it is not without disadvantage. The large travel and high elasticity of the torsion bars results in a "rocking" motion when the tank is moving or coming to a sudden stop.
How to properly adjust torsion bars?
Locate the adjustment bolts on both sides of the torsion bar. Put a car jack beneath your car frame and lift the tire off of the ground. Place a socket and ratchet wrench on top of one of the adjustment bolts. Turn the torsion bar bolt clockwise to lift your car to your desired height.
Do torsion bars fatigue?
Torsion bar springs are dynamically loaded machine elements which can break due to fatigue.
What do upgraded torsion bars do?
When you use a factory or standard torsion bar to create more lift in your vehicle, you have ultimately used their maximum torsional value. Whereas heavy duty torsion bars will give you the desired lift without maxing out their torsional values.
What are the disadvantages of torsion bars?
A disadvantage is that torsion bars, unlike coil springs, usually cannot provide a progressive spring rate. In most torsion bar systems, ride height (and therefore many handling features) may be changed by simply adjusting bolts that connect the torsion bars to the frame cross member.
What does turning up torsion keys do?
A torsion key lift is an easy and inexpensive way to increase vehicle height without buying a lift kit. It utilizes the torsion bar suspension's unique design to raise or lower the vehicle's front end.
