The Wicked Bilt Electra-Steer power steering kit for the 2011-13 John Deere Gator XUV 550 is a bolt on system that significantly reduces steering effort and diminishes steering wheel jerk caused by uneven terrain. This is a torque-sensing unit that increases assistance as torque or resistance increases at the wheels. Unit mounts under the dash / hood area. This John Deere Gator Electra Steer kit fits on all XUV 550 models made in 2011-2013. This kit is BIGGER, BADDER, & BETTER than our earlier successful models.
