Leaf springs are old tech, but they’re still relevant as they’re used in passenger vehicles to date. Torsion bars, however, are slightly more obscure as it’s been a while since they’ve ...

So what are torsion bars? Basically they're straight steel bars that work like coil springs but twist for damping rather than compressing as coils do. The bars can be found in the front ...

A torsion bar is basically a straightened-out spring that twists rather than compresses. Though generally more durable than coil or leaf springs, torsion bars can wear out like any other moving part.

Both of these designs, however, lack the compact packaging and adjustability of a torsion bar suspension system. Sure, you can replace the springs in a coil over IFS or straight axle suspension ...

The inboard suspension design favors aerodynamics and conceals the dampers, springs, torsion bars, anti-roll bars, and other components behind or under the vehicle to improve airflow. In the 1970s ...
