So I am the second owner of a 2016 Nitro Z21 with a tandem trail star trailer. I’ve seen post about measurements from the original equipment it the previous owner had put on the kit and raised the fenders. I have contacted him and he believes it was the k71-652-00. I’m wanting to get my fenders back to where they were originally at and looking for help on which kit would accomplish this. Trailer is a tandem axle 2015 trail star. 26 inch leaf springs and 33 inch axle measurements. Just not sure on the center pivot?
