I purchased the same lift/leveling system from Nick@GotExhaust plus a Synergy adjustable track bar. Heres my brief review: packages arrived in 2 days, before I even checked tracking numbers! Thanks Nick@GotExhaust. My goal was a comfortable, well handling ride with AEV Katla’s and Toyo 37’s. The wheels are being painted, so had time to compare the lift (it’s really a leveling kit) with factory tires. The front measurement was 40 3/8 it is now 43 1/8. The rear went from 42 1/4 to 42 1/2. I can easily fit 37’s now. However, the unanticipated, biggest improvement is ride quality. With the Eibach coils and shocks the truck just glides down the road. Handles bumps much better also. This is the best “bang for your buck” in lifting and ride quality.
