JKU Old Man Emu Lift specs

[shays4me]

I just installed my Old Man Emu springs today on my 18 JKURR. I wanted to give a detailed account of how much lift was achieved and the springs that that were used. My JKU is stock other than a Warn M8000 winch with synthetic rope on a bulldog plate in the factory steel bumper. I've also added a Mopar bar to the bumper. The rear has an AEV bumper and tire carrier and I have a hard top. There were no changes done to the Jeep except the lift and I measured it all on the same concrete pad before and after. My front factory springs were 19 and the rear were 61. The OME springs I used were 2619 with a OME 10mm trim packer up front and 2618 in the rear. I also used teraflex bump stops front and rear, a teraflex track bar bracket and sway bar links. I rounded out the lift with a set of front brake line brackets from pro comp and the rear are no name. The shocks on the Jeep are still the factory rubicon shocks. They were just a long enough and I plan to change them as funds allow. They didn't restrict the springs at normal ride height. The front lift acheived was 2.75" and the rear was 1.75". I took the Jeep for a drive to settle everything and adjust the steering wheel before measuring the height at the frame on both ends. Also, I checked to see how much Caster was lost with the lift and it was .6 of a degree with a digital angle finder. Overall feeling is that the new springs ride a little stiffer and it doesn't wander any from the caster change. This is my second time installing this lift on a JKU and I was happy enough with the old springs to use them again. Now for some tires........

I think you will find you have very little down travel with stock shocks especially up front, you should at least get some shock extenders until you get new shocks. I found that with similar lift a set of TF sport arms gives near perfect caster ie ~5*. If you are looking for a nice riding set of tires that are are taller than stock and can be had dirt cheap look at some Falkens in 255/80-17 I run a set of these on my stock rims as an extra set when I don't need my 35's. They are over an inch taller than stock and do well off and on road.
what do you get using this diagram?

Here is how the 255/80-17 on stock rims look.

Ive got 12 3/8" for the spring and 21 1/4" for the shock on the passenger front. Do you know if there's a diagram like that for the rear suspension? I really like that color! I wanted that but my wife liked the grey one better.
