Review on SuperATV EZ-STEER Power Steering Kit: Enhance Your Polaris RZR 900's Performance (2015-2020) by Howie Broyles

A lot of money but worth it. It makes a huge difference, the biggest of which is eliminating feedback when hitting stumps. If you previously drove a tire onto a tree stump hidden in the grass, the wheel will break out of your hand. The second difference is the comparison of day and night from the steering without power steering to this kit. You can ride all day with just one hand. Installation takes 2-3 hours. No special tools are required.
