We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It provides a 1-1/4" keyed output shaft to drive auxiliary equipment like a hydraulic pump, winch, or dump body via a driveshaft. The PTO engages and disengages using an air‑shift system, and it uses a 21/37 gear ratio with a 5-P-1077 input gear. You typically replace this unit when the original PTO leaks, the gears wear out, or the air shift fails, restoring reliable power to your auxiliary equipment.
