QUESTION-- DO I NEED NEW COILS? If yes, both front and back?
BTW I bought a full coverage skid plate from RCI to help protect the underside.
THANKS IN ADVANCE!

IMO, yes and yes, and not just to get the height you want. This is my post from the previous page:

General observation about original springs: replace them when you do your shocks. People often think the shocks make the ride, but as
Motor Trend explains:
==
The springs are the foundation of a suspension system. They are what allow the up and down movement of the wheels with minimal impact on the chassis and the rest of the vehicle. The primary job of springs, though, is to hold up the weight the vehicle and its cargo.
==
The "youngest" 4th Gen (2009) is now 13 years old and an average one is likely at 150K or more. That means the typical 4th Gen's original springs have been carrying a 4,500 lb. SUV for well over a decade and the equivalent of 6+ times around the world. When I did my suspension, I knew I'd always wonder how different/better the ride would have been if I didn't do the springs. They're not that costly either so IMO, running new shocks with original springs doesn't make sense.

Plus you're adding more weight with the full skids. Your truck and your $ but that's my 2 cents.
