This is what I ordered:
Ironman Rear Coil Springs JEEP015B
Ironman Front Coil Springs JEEP014-C
Spring Load Range Load Range "C" and yes, they are the ones listed for the CRD with bumper guard, winch, etc...

If the Bilsteins don't work out on the rear, I will order the longer Ironmans.
Thanks for the good info.

I've been running the 014 C's in the front now for about two months with Bilsteins. No winch bumper on there yet. Ride is firm but swallows up big hits real good. Running the 015B in the rear with MLL's for Dodge Dakota. Everything taking abuse well so far. They should do you well.
