These suspension components are pivotal in connecting the vehicle’s chassis to its wheel hub. They utilize bushings and ball joints to permit controlled movement, facilitating both vertical travel and steering. Placement varies, with upper and lower configurations commonly found on independent front suspension systems.
Properly functioning units are vital for maintaining appropriate wheel alignment, ensuring optimal tire contact with the road surface. This contributes directly to vehicle stability, handling responsiveness, and braking effectiveness. Their design and construction have evolved over time to enhance durability and accommodate increasing demands on vehicle performance.
