The Chelsea 249GMLLX-B471 or 249GMLLXB471 is a 249 Series Power Take-Off Assembly designed for Ford Super Duty trucks equipped with the Ford 6R140 TorqShift 6 automatic transmission. It mounts via a 6-bolt Ford-pattern flange and uses hydraulic (PowerShift) engagement. The 249 Series is the only PTO in its class with a patented noise-reduction system specifically engineered for this transmission family, addressing the torsional noise common on these applications. The series carries an intermittent torque rating up to 200 lb-ft (271 Nm) and delivers 57 HP at 1,488 RPM. Internal pressure lubrication (X-lube) is integrated, and a single-hose connection with built-in actuation valve simplifies installation. Typical applications include service trucks, tow and recovery, small dump trucks, and aerial and fire and rescue units. Call us to confirm proper fit for your specific truck build.
