The Chelsea 252GDHVP-B51449 or 252GDHVPB51449 is a hydraulic-shift power take-off from the Chelsea 252 Series, designed for Allison 1000/2000/2400 series automatic transmissions and RAM truck applications. It mounts via a 6-bolt pattern and drives through a 1-inch round output shaft with a 1/4-inch key. Shaft power output is rated at 11 HP at 500 RPM and 23 HP at 1000 RPM, with an intermittent torque range of 101-200 lb-ft. The integrated cartridge valve and single-hose connection simplify installation, eliminating the need for remote solenoids or multiple hose routings. Weather-tight electrical connectors and a controlled compression interface gasket are standard. Call us to confirm proper fit for your specific transmission and chassis.
