Breanna Martinez – Marketing Communications Specialist II
Designed for use with Ram TorqueFlite HD/ZF PowerLine transmissions, the Z21 Series and Z25 Series PTOs are compatible with Dodge 3500, 4500, and 5500 trucks starting from the 2025 model year. This transmission supports left, right, or dual PTO installation.
Both models are clutch shifts, have an integral solenoid, a low-profile housing, and use a single gasket, which removes the need for backlash measurement.
The PTO openings are standard on diesel trucks and optional on gas trucks.
