Since installing my bumper and winch, my truck went from leveled to about 1" low in the front. To handle the extra weight on the nose I'm looking at F150 coil springs.

My options:

F150 Heavy duty:

Type One Tangential End; One Pigtail End
Inner Diameter 3.68"
Wire Diameter .81"
Median Design Height 13.00"
Design Load 2365
Spring Rate 811
Approximate Free Height 15.92"

F150
Type One Tangential End; One Pigtail End
Inner Diameter 3.68"
Wire Diameter .75"
Median Design Height 13.00"
Design Load 2285
Spring Rate 552
Approximate Free Height 17.14"

Compared to Expedition springs from the same maker:

Type One Tangential End; One Pigtail End
Inner Diameter 3.69"
Wire Diameter .75"
Median Design Height 12.50"
Design Load 1924
Spring Rate 552
Approximate Free Height 16.00"

My question then - Considering the second F150 set, same spring rate but ride .5" higher vs the first set which are not just half in taller, but also 250lbs 'stiffer'.

Thoughts? Help? Suggestions?

Not sure I realized I had them? If I did I suppose because that'd do nothing to compensate for the extra weight. Maybe that's what I was thinking?

Stiffer spring rate means harsher ride, but it should hold the front end higher. Also Darin, I'm sure you remember the bilstein adjustable lift shock debate from a few weeks ago, could look into those. I can post the thread when I get home if that would be helpful

Yeah - i recall the thread; thanks! Im leaning towarsds the stiffer springs - might help control the weight better, vs simply raising the perch.

I haven't done anything yet. I'm pretty sure I'll get the stiffer springs.
