Torsion Bar

Print

Torsion bars are used to control ride height and ride quality on 4WD models. The vehicle height is adjusted through an anchor adjustment bolt that increases or decreases the angle of the torsion bar.

Increasing or decreasing the bar angle changes the angle of the suspension arms.
