The Dynatrac setup is great. I got 1-1.5mpg increase in fuel economy which helped offset the 1.5-2mpg loss in fuel economy when the fuel formulation changed 10yrs ago. I also love the manual hubs with this kit, I got Warn hubs and not the Dynatrac. Steering feels a bit freer/looser. I don't have to worry if the front end is engaged because of a leaky vacuum line or if its frozen from getting immersed in freezing water.
