Torsion Bar Spring
A torsion bar is a straight steel bar that acts as a spring by twisting along its length.
What is Torsion Bar Spring?
One end is fixed to the frame and the other to a suspension arm. It is used on some pickups, SUVs and older cars. Ride height can often be adjusted at the anchor.
How it works
When the wheel moves, the arm twists the bar, which resists and springs back.
Why it matters for your car
Adjusting the height changes wheel alignment, so alignment should be checked afterwards. A sagging bar lowers one corner of the vehicle.
