Pull Rod Suspension

Pull Rod Suspension is a mechanical system used in race cars where the suspension components are arranged to pull on a rod when the wheel moves upward, transferring this motion to control the springs and dampers.

In this configuration, a diagonal rod connects from a low point on the chassis to a higher point on the wheel assembly. When the wheel moves over bumps, it pulls on this rod, which activates a rocker mechanism that compresses the springs and dampers. This differs from push rod suspension, where the force pushes rather than pulls.

Pull rod suspension offers significant advantages in motorsport, particularly Formula 1. By positioning suspension components lower in the chassis, it lowers the car's center of gravity and improves aerodynamics. However, it can make trackside adjustments more difficult compared to push rod systems.
