XK & WK weight and weight distribution comparison !! for OME coils rating selection

While making a comparison between the weight of XK and WK in order to determine how much of weight the XK adds on each axle more than the WK ,, I found a strange finding !!

The compression was made on the base model on both XK and WK (4.7L & 4WD)

For XK: weight: 4968 lb........weight distribution ratio (F/R): 44/56....... Weight on front axle: 2186 lb.......on rear axle: 2782 lb
For WK: weight: 4630 lb.......weight distribution ratio (F/R): 54/46....... Weight on front axle: 2500 lb.......on rear axle: 2130 lb

The strange thing is that the weight on the front axle in the XK is less than the WK by around 314 lb !!

I did that to select the right OME coil rating (heavy or medium) as the heavy one should be used only in case there is constant load on the vehicle. And the exiting OME coils are only available for the WK only, and the XK should look like a constant load on the WK and the heavy OME coils should be used.

But after this comparison, I think the correct OME combination should be medium in the front and heavy in the rear.

What do you think?

I see that it's a different ratio, but is that why? And why would it be different?

Yea ,,, its not only different, they are swapped .. I mean, in WK the front is heavier and in XK the rear is heavier.

your question about why the distribution is different is what I'm trying to find!!

what I could think about, is that the XK mainly differs from WK in the back, extra third row which sets directly above the rear axle and the XK is longer from the rear axle to the end of the vehicle, and that extra weight (which set after the rear axle) is somehow raising the front end and make the XK lighter in the front !!

I don't think my bathroom scale will work, LOL

I don't even know where scales are out here. I would like to see how much it really weighs. I think they say on the tag thats on the drivers door next to the seal, but I am not sure. I will try to get out and check it soon if I get a chance before it gets dark.

Anyone know??? I would also like to see the difference in the weight between the different models 3.7/4.7/5.7 and and the deisel for the XK's and the XH's.
