We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It typically includes bushings, seals, O‑rings, and hardware needed to eliminate play caused by worn camshaft bushings. Replacement is necessary when you notice uneven brake shoe wear, excessive camshaft end play, or seal leaks that affect brake adjustment. Restoring the camshaft assembly helps maintain consistent stopping power and prolongs the life of related brake components.
