Spring Rate

[daniel3507]

Does anyone know what the factory spring rate is? I'm looking at Radflo and youre able to pick your spring rate but I'm not sure what would be a good choice. Not planning a front bumper but I do have a winch in the garage that will be going on.

This thread may help. It talks about the Ford tuned and standard Fox 2.0 coilovers.

It states both are 550 springs. I have the Fox 2.0 (non Ford tuned version) and I think it is a good baseline. It is a softer spring, but not mushy like the OEM shocks.)

Hmm, interested as well.

I found a chart with the front spring rate a while back. It’s like 350-433 depending on the trim level. My Belltech springs are 628 per Belltech technical support.

I would speak with the seller or Radflow to see what they recommend for what you are wanting to do

The Eibach have 550 lb springs, the OME Nitrocharger have 605 lb springs.

If you're looking to add the weight of a winch, but not a bumper, you could probably get away with 550. Since I have the bumper/winch, I went 605 and have 1" strut spacers to keep the front suspended. The 550 could not keep up with a bumper and winch.

Im on Icon coliovers and went with a 700 pound spring. I have a winch and tube bumper on the front. For the icons I feel the 700 rides pretty good and stopped some of the front diving under braking.

How much does the bumper weigh?

Are you on a long travel set up???
Most with the bumper and winch, do
well with the ICON 2.5 / 650lb.spring.
Only other time I have seen someone needing a 700lb. coil springs was on a
+3.0" long travel setup...

with the winch plate and all I’d say around 100 pounds at least. Haven’t weighed it.

i am on LT now but I’ve been running the 700 for a while now before the LT. IMO the heavy spring felt a lot better. Stopped some body roll and the front dive decreased under braking.
