more lift to the superlift

[06JeepXKHEMI]

What issues did phunkeydude have? I really don't see an issue what so ever. Order the superlift, keep your HD coils, cut off a coil, install and be sad cause my jeep is still bigger sitting on brand new 34 inch MT/R's. Bwhahaha

Just let me get the 33's Ill chop up the XK for them, I do not care!!!

EDIT: Brain fart.... these part numbers are the REAR Springs

So just because i've been thinking about this and had a theory, I had to put some numbers to it and found something interesting.

OME992 = WK MD = XK LD = 13.6" free height, 7.2 coils, 240 lbf/in, 17mm wire
OME993 = WK HD = XK MD = 13.6" free height, 6.6 coils, 280 lbf/in, 18mm wire

OME992 with 1 coil removed:
11.7" free height, 6.2 coils, 280 lbf/in <---Note that this is like running the OME993 spring rate and 2" less pre-load in the assembly

OME993 with 1 coil removed:
11.5" free height, 5.6 coils, 330 lbf/in

Based on this, I think I'm going to try an OME992 with 1/2 coil removed:
12.7" free height, 6.7 coils, 260 lbf/in <---- This will give a spring rate in between the OME HD/MD springs, and an inch less preload in the assembly. So it should ride good, and if needed I can always cut another half coil off.

Note that free heights are estimations due to the fact that the top side of the coil closed/ground. But their relative differences to each other should be maintained for comparison purposes.

But still need to know whether kmax/phunk used the OME992 or OME993 spring. I have a feeling, based on the "stiff ride" comment that they cut down an OME993 spring and ended up with a 330 spring rate.

My question is, how do you figure out the spring rate of a coil that has been cut down???

[Pixelcodex]

And thinking about it some more.... if he did have the XK MD springs (WK HD), which is what I currently have, I may consider swapping them out for the XK LD (WK MD) springs to mitigate some of the issues phunky had which may allow me to cut less than a full coil off.

Are you talking Old Man Emu or stock springs? I was under the impression that OME springs were rated the same for both the XK and WK...

[Matt]

You're missing the part about the difference in coils, if my coils are stiffer I'll need to cut more off than phunky did.
His issue was the ride was stiffer from the cut coil .... hence why kmax had custom coils made. so, already starting with a higher spring rate + having to cut more coil off = even stiffer suspension. That's the issue. It all boils down to which OME spring they tried using..... hence my question

Lmao at cricket.....dude dont feel bad I have my xk stuff shipped to matts so my fiance wont find out LOL

[kmax]

Matt - going back a few posts...

As I recall I had the OME992 springs, but I think I can dig up the paperwork and find out for sure.

[Matt]

I would appreciate that. Thanks!

[Matt]

Sounds good. Looks like there's definitely some merit to trying the same method with the 990s.

What springs did txbajacommander use?

Based on Kmax and Phunkydude, as well as Omelet on JF (all of whom who have done this), I wouldnt even attempt it with the OME HD (XK medium duty) springs. So if you have a choice, give the OME MD (XK light duty) springs a try and let us know how it works out for ya.

That'll help me figure out how much of a coil I want to cut off as well

I know with the XK medium duty springs i had to cut one coil off to get them to work and even then it was a PITA to do!
