Warn winch upgrade kits boost the power and performance of your A2000 winch. These kits allow A2000 owners to raise the capacity to 2,500 lbs. The mechanical rotary switch is replaced with a longer-lasting mini-rocker control switch, and a sealed, industrial-style contactor with greater amp draw is also provided. The upgrade kits also include larger 6-gauge battery cables so your motor can deliver the proper balance of speed and torque more efficiently. Pull more power from your winch with Warn upgrade kits.
