I installed a lift kit on a Polaris Ranger RZR. The kit raised the vehicle about 2 1/2" inches to allow room to put bigger tires on it. The $200 kit consisted of these 8 steel plates and a few bolts and spacers.
It was a nice warm sunny day so I decided to work on it outside. The person in the photo is Carl, one of the local high school students. He is working with me this week as part of a vocational training unit at school.
The plates bolt on to the A-arms and raise the shock mount up a little. I had to use a ratchet strap to compress the springs to get everything lined up. The whole project took about 3 hours.
