So I have a ‘19 4Runner TRD Pro and love it. How ever after adding RTT, awning, etc I am getting some sag. What I am looking for is stiffer springs, not longer springs, lift. Wondering if the front and rear coil springs on a ‘19 GX 460 are the same size as those on my stock suspension Pro, but stiffer as a GX weighs 5100 lbs and my Pro is 4750. As some of you are probably aware I do not have KDSS but the stock Fox Pro suspension. So looking for stiffer springs buy stock size to stiffen, regain stock ride height but not lift. Anyone know? Many thanks
