Kingpin

A kingpin is a crucial component in vehicle suspension and steering systems, acting as a pivot point around which parts like the wheel and steering mechanisms rotate. Typically a large bolt or pin, it connects the wheel assembly to the suspension, allowing steerability and stability. In essence, the kingpin ensures smooth steering function and helps maintain proper alignment of the wheel, contributing to vehicle safety and handling. Its integrity is vital; a worn or damaged kingpin can lead to steering issues and uneven tire wear.
