I bought the front kit with 1/2" springs for my 2020 Power Wagon. Install was pretty straight forward and I had no issues swapping the springs and shocks. The front track bar is set up for Thuren's 1-1/2" springs though, so I had to adjust it to fit. Superb quality and better ride over the stock parts for sure!
One part of my order was on a small backorder, customer service made sure to let me know immediately and keep me updated on the progress. They even shipped part of my order sooner than the rest. The backordered stuff came in a week later and was immediately sent out to me. Very happy with my interaction with Thuren.
