C $39.74. The torsion beam functions both as wheel locating arm and as an anti-roll bar to resist lateral motion of the wheels as the body leans in turns. It takes up less of the vehicle's interior volume than coil springs. Manufacturers change the torsion bar or key to adjust the ride height, usually to compensate for heavier or lighter engines. Torsion bar suspensions are used on combat vehicles or tanks like the T-72, Leopard 1, Leopard 2, M18 Hellcat, and Abrams (many tanks from late in World War II used this suspension), and on trucks and SUVs from Ford, Dodge, GM, Mitsubishi, Mazda, Nissan, Isuzu and Toyota.

Axle Flex was discontinued for the 1936 model year. This stepped piece rests on a large bolt which contacts the bottom edge and adjusts the amount of tension and pre-loads the bar. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance. These bars do this by absorbing some of that force by moving with the bumps rather than acting in opposition to them. Torsion bar suspensions are used on combat vehicles or tanks like the T-72, Leopard 1, Leopard 2, M18 Hellcat, and Abrams (many tanks from late in World War II used this suspension), and on trucks and SUVs from Ford, Dodge, GM, Mitsubishi, Mazda, Nissan, Isuzu and Toyota.

Twist-beam rear suspensions were pioneered on the Volkswagen Golf[citation needed] in the early 1970s, and remain common on compact cars and minivans. The other end of the torsion bar fits into a piece of steel which has steps machined into it. The effective spring rate of the bar is determined by its length, cross section, shape, material, and manufacturing process. The torsion bar has a hex shape machined into one end of it that slides into a hex opening in the lower control arm of a vehicle's front or rear suspension. The single torsion bar was mounted through the frame sides behind the rear axle and then attached by arms and links to the front side of the spring U-bolt plates.
