SPRING PIN KENWORTH

This is a threaded front spring pin that secures the leaf spring eye to the frame hanger on heavy-duty Kenworth and Peterbilt trucks. The pin threads into a matching bushing and bracket, allowing the spring to pivot as the suspension moves. It is replaced when the pin or bushing wears, causing looseness, clunking noises, or uneven tire wear, and is typically changed during a front-end suspension rebuild.
