A torsion key lift is a technique for raising the ride height of torsion bar suspension cars. A torsion key lift can be accomplished by adjusting the vehicle's existing adjusters or replacing the factory keys with a set designed to raise the ride height. It maintains the vehicle's predetermined size by controlling the distance between the bar and the ground.
And you will use a torsion bar tool to raise a torsion key safely. A DIYer can install a new key and adjust the bars in less than two hours, while a skilled mechanic can finish the job in less time.
Signs of Torsion Key Lift Problems
The suspension and the rest of the car may suffer if the torsion bars are lifted. Here are some issues you can run across after installation of a torsion key:
Poor Ride Quality: The stock torsion key is raised towards the cross member by cranking it. As the key reaches the top and can no longer travel higher, the torsion bars cease rotating past that point. This could explain why some drivers say that their cars ride rough after a torsion key lift. Stock or Short Shock Absorbers Bottom Out: Some people believe that a torsion key lift is more cost-effective than buying a lift kit. Adjusting ride height this way without shock extensions or longer shock absorbers, on the other hand, may cause suspension issues.
Stock shock absorbers are made to fit between the suspension and the chassis. When the car droops, lifting the torsion bars might help the bottom of the shock come out faster. The force of the collision may surpass the dampers' ability to absorb it, resulting in increased wear or damage. Squeaking or Whining Noises: You may hear squeaking or whining sounds coming from the vehicle's front end after a torsion key lift. While engine and road noises may obscure these sounds at high speeds, they become more evident as the car slows down.
Due to a torsion bar adjustment, the drive axles may have exceeded the recommended CV angles, causing these noises.
After a torsion key lift, you may hear squeaking or whining sounds from the vehicle's front end. Misaligned Tires: Changes in ride height may impact wheel alignment measures. The alignment angles and irregular tire wear can both be affected by a torsion key lift.
Even if the factory torsion key was not replaced, it's a good idea to complete a wheel alignment after raising a car.
Damaged CV Boots and Drive Axles: Because altering the torsion keys changes the angle of your vehicle's front suspension, the CV boots and drive axles may be damaged. Your vehicle's front suspension tip is altered by changing the torsion keys.
You can elevate the front end if you want the front and back end to be the same height. On the torsion bars of most trucks, leveling keys are placed. A couple of cranks will lift the front end a little. You need to require a torsion key lift to extend the front end. These aftermarket keys are installed over the levels and add a few extra turns for added height.
