Which statement about torsion bar front suspension is true?

• A. Torsion bars must be replaced in pairs
• B. Torsion bars are non-adjustable
• C. They can be installed on either side
• D. They can be used on SLA suspensions

Answer: (D)

The statement that torsion bars can be used on SLA (Short-Long Arm) suspensions is accurate. Torsion bar suspensions are adjustable systems that provide a means to control ride height and spring rates, and they are among the various types of systems that can be utilized in SLA configurations. SLA suspensions have both upper and lower control arms of differing lengths, and integrating torsion bars into this setup allows for effective management of vehicle dynamics such as stability and handling. The design utilizes the inherent flexibility of the torsion bar, where twisting it adjusts the tension, effectively acting as a spring. In contrast, torsion bars must generally be replaced in pairs due to performance consistency and balance across the suspension system. Additionally, while some torsion bars can be adjustable, many are designed without adjustability. They are typically side-specific in their design and intended installation, meaning they should not be mixed or installed on opposite sides without specific adjustments or considerations.
