The Muncie P58Z1110XX5BBBX is a P58 Series power takeoff built for the 2022 Paccar TX-8 transmission. It outputs at 121% of engine speed and is rated for up to 80 hp (60 kW) at 1,000 RPM, with a maximum torque of 420 lb-ft (569 Nm) intermittent/continuous. Engagement is handled by a pneumatically shifted clutch pack, and the internal bearings are pressure-lubricated, keeping them oil-fed without external service points. The SAE B mount pattern is compatible with most common gear pumps, making this unit straightforward to pair with hydraulic systems already on your truck.
