The Chelsea 252GDHVX-B51137 or 252GDHVXB51137 is a hydraulic-shift power take-off assembly from the Chelsea 252 Series, built for Allison 1000/2000/2400 series automatic transmissions and RAM truck applications. It mounts via a 6-bolt pattern and delivers power through a 1-inch round output shaft with a 1/4-inch key. Intermittent torque rating falls in the 101-200 lb-ft range (check application pages for actual torque ratings for your specific installation). Shaft power is rated at 11 HP at 500 RPM and 23 HP at 1000 RPM, with output capped at 25 HP. The integrated cartridge valve means a single hose connection handles hydraulic control, simplifying installation. Weather-tight electrical connectors and a Controlled Compression Interface Gasket are included as standard. Call us to confirm proper fit for your transmission and chassis.
