Hi guys, could anyone tell me what spring rate to get to replace my sagged ones out front. I currently run 2” lifted Old Man Emu springs on my 2008/09 Wrangler Unlimited Rubicon auto soft top, with a winch bar and winch out front. I specifically need a spring that will flex for off roading. Are the OME 2619’s the right ones? Will not be replacing the rears and both the front and rear shocks are near new. Tia, Steve.
