Loved by off-roaders who compete, it's our fastest winch. No load retrieval speed for the M8274-50 is 73.4 feet per minute and that's not all. At 150 feet of 5/16" cable, it also has a very long line capacity. Its unique spur-gear drive train and upright design are totally rugged. Its braking system delivers smooth operation with superior heat dissipation. Roller fairlead, remote control on 12-ft. lead, free spool clutch and battery cables are included.
