What is a strut bar? How does a strut bar work? What forces act on the strut bar through the suspension? A strut bar, or tower bar, connects the top strut towers together, in order to increase the rigidity of a vehicle by allowing both strut towers to react to compression and tensile forces. A strut bar plays a larger role for MacPherson strut vehicles, however it can still be important in vehicles with double wishbones as well for compensating vertical forces.
