Ok maybe stupid question here for me cause I am in learning mode when it comes to 4x4. I am coming from the car side of the house and learning rather fast. What I am wondering is when dealing with suspensions of cars you can purchase aftermarket coil springs with different spring rates, taller and lower springs, etc... allowing you to change a myrad of characteristics of your vehicle with just a coil spring change. When it comes to IFS lifts they cost an arm an a leg. Are there no companies out there that make taller coil springs to give more lift to our trucks (Suburban in my case)? If not I am wondering why no one has gone and found a manufacturer to produce some or looked at OEM parts bins for taller springs from different trucks that would allow more lift. I am talking on the smaller side of things here. I am not looking for a spring that will give 10" of lift if that is what you were thinking. I am being practical and saying maybe 2-3" from a coil spring change. Any input from anyone on this both negative or positive? I really dont want to shell out $500.00 or more for a lift kit when I could just get a small lift out of a spring change. Thanks for the help. John
