yeah, I look at it this way on the price. I can spend $700 for a 5 inch lift, which really needs 37" tires which means more $. Or go with a 3" carli system for $1700, starter kit plus adjustable track bar. In the end the Carli would be less expensive, if you aren't looking for a huge ride and top ride quality. Then I could save up for better shocks over the 5100's over the next few years. Waiting on pricing back on the 2" leveling kit from RC to see if running them for a few years would be a viable option to go to 6" in the future. I have been back and forth on level vs lift since I bought the truck. Love the look of a 6", but like the ride quality provided by Carli.
You may also want to see what it takes to be a thuren or pure performance. Both make good quality systems for the 3/4 ton. Thuren's 2" leveling kit is a great starting position, both price and performance. Less than a $1000 for coils/4 shocks/ and adjustable track bar. No need for control arms or end links.
