I'm not sure why anyone would want a softer ride than the 36Rs provide. Compared to the stock springs, they ride like a Cadillac.

That said, I have no experience with the softer 14F springs, so take my advice for what it's worth.

Thanks Matt. I value your advice. I was just wondering.

FWIW...

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:

Hi Steve-
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.
Best Regards,

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.

It is basically the height of the arch in the spring.

While were on the subject of free camber the 36r is 205mm which converts to 8.07 inches. Bds 3.5 inch springs state there 8 inches freestanding. How much lift should a guy expect from them in comparison? Why do the ome springs have more camber and less lift are they softer so they will compress more?

Who ever said less is more never owned a jeep.

I suspect the OME springs are softer. They are known for their comfortable ride qualities, and flex. I can certainly attest to that.

It is also possible that the BDS 'freestanding' measurement is a different measurement than 'free camber'. See link for the possible difference in measurements: http://mgaguru.com/mgtech/suspensn/rs105.htm

Based on the pictures then the free camber is basically half of the free standing height. Since the two measurements (from bds, ome) are both close to eight inches that would make the ome spring twice the height. When I called bds they gave me a free standing measurement of 8 inches the ome spring has a camber of 8 inches. Technically it would be larger than the bds spring. None of this makes any sense to me the measurements have to be taken from the same place. I imagine the guy at bds gave me the wrong measurement. I am going to call bds and ask for the camber measurement then I will post it up.


Edit-
I just got off of the phone with bds and they told me their camber is measured at 7 1/2 inches so with ome being 8.07 inches technically out of the box they are a taller spring.

Anyone know if the 4 degree shims would be needed for a '73 CJ5, or...?

Just ordered all my stuff and there are quite a few differences in the "intermediate" kit from the stuff here. It hasn't arrived yet, so maybe the instructions will tell me this, but if anyone knows I'd like to order the shims now...

Any other tips from the intermediate crowd that have done this would be greatly appreciated!

And BTW, doing the Rocky Road SUA kit with the heavy rear 2 1/2 OME YJ springs all around. Still haven't decided on shocks...

The world would be a better place if being stupid hurt...

The heavy rear OME springs will have a 2 degree shim that will be backwards for the fronts, unless the supplier reverses them.

The safe bet is to install the springs with the provided shim (reversed on the fronts), have the alignment professionally checked, then make any necessary adjustments.
