This is a bolt on system that significantly reduces steering effort and diminishes steering wheel jerk caused by uneven terrain even in the biggest SXSs. It's a torque-sensing unit that increases assistance as torque or resistance increase at the wheels. Unit mounts under the dash and does not decrease leg room. The BRP Maverick side x side Electra Steer Power Assist Kit fits on all Maverick models made in 2013 equiped with Rackzilla rack & pinion. This kit is BIGGER, BADDER, & BETTER than our earlier successful models.
