A torque relief device for use on sucker rod pumps that relieves sucker rod torque deep in the well. Although the device will relieve torque for all sucker rod pumps it will be most effective for use in long stroke sucker rod pumps; further although the device will be effective on all sucker rod pumped wells, it will be most effective on deviated wells where sucker rod torque is the greatest. The device includes a square tube fixed within the well. Inside of the square tube a wheeled rod guide moves up and down with the sucker rods but is restrained from rotating by the wheels reacting with the tube. At each end of the wheeled rod guide is a swivel that allows the sucker rod to rotate thus dissipating the sucker rod torque.
