I ended up taking this one step further and wanted to share what I found. Quadratec sells the CS014F as a 2.5" Lift spring (http://www.quadratec.com/products/16090_5032.htm
) which got me wondering if there was more info to be had. So, I emailed ARB and asked for specs. I got a very prompt reply with some good info. Here is what I got:
The springs you are inquiring about are Jeep Wrangler YJ application. We have 3 springs available. CS036R, CS037R, and CS014F. Technically the 36R and 37R are rear spring applications and the 14F is the front, but plenty of people use them on all 4 corners. The rates, leaf count and arch are as follows.
CS036R- Rate- 188 lbf/in, 5 leaf, 205mm free camber.
CS037R- 188 ,5 leaf, 185mm free camber.
CS014F 148 , 4 leaf, 210mm free camber.
So basically the only difference between the 36R and the 14F is the spring rate (presumably because it has one less leaf, which also explains the cost difference). That would make the CS014F sag a little more making it seem like there was less lift. Which would result in the 'rake' that Glenn mentioned.
In a follow up question I was also told that the 'F' springs do not come with the caster correcting wedge. Not a big deal if anyone chooses to use the 14F since that gets replaced anyway.
