So. I've been putting a lot of thought into what kinda lift I want to do the the Jeep, and I've come up with a couple options that would work best for me.
Primary objective is off road performance, and cost. And durability. Lol everything except on road. If I wanted a missile, I'd have gotten a 5.7 with low miles.
I have a few questions that I haven't found any specific answers on yet. First: What about the OME HD kit gives you the lift? Is it the springs being taller? Just being stiffer? Or is it the struts?
Second: Would it be wise to try and put the HD springs on some Bilstein 4600 struts? Would there be any advantages to this, cost or performance wise and would they even fit? How does the performance vary between OME and 4600 struts? And, would I get the same lift height with both of em?
Third (don't worry, it'll be over soon): What are the REAL WORLD, not what the brochure says, off road performance differences between a spacer kit, such as the rocky road, and the OME kit? Is the old man emu actually THAT much better? How are the flex characteristics? Lol because the rocky road sure is a whole lot cheaper.
And last: Anyone have experience with the Rancho 9000XL adjustable shocks that come with the rocky road kit? Supposedly they're kinda stiff, but I can't imagine they'd be stiffer than the stickers all the way softened. How would they compare with the Bilstein 5100?
Thanks in advance guys, I know this is a lot. Please feel free to only answer a couple if you don't have much time or experience with only some of the questions.
First off, I'd say check out my garage since we have the same year Commander with the same engine and you can see what route I went;
I have the 2" Rough Country lift kit with Bilstein B6 4600 front shock absorbers (Part # 24-186797) and the stock springs - they are technically shock absorbers by the way - not struts.
I've added JBA Upper Control Arms for lifted XKs (Part # JBA-6.7.00-SLB) for extra stability and to help deal with the extra weight from WAM front bumper.
I have Bilstein 5100 rear shocks (Part # 33-225807) with new, slightly heavier, Hemi-rated rear coil springs - (JustForJeeps Part #'s 52124213AA & 52124214AA) for towing purposes.
Now to try and answer some of your questions;
I have no experience with the Rancho 9000XL adjustable shocks but I have heard that they are very good shocks and there are some guys here on the forum that run them - but the rest of the Rocky Road lift kit leaves a bit to be desired, so I have heard.
I opted to mix and match my own components.
As far as adding HD springs up front, I don't think there would be much benefit to doing that - unless you just want the piece of mind knowing that you replaced them, I'd imagine it would probably stiffen your ride a little bit upfront when off-roading.
I can't really speak intelligently off road performance differences between a spacer kit, such as the rocky road, and the OME kit because I have never rode in or driven an XK with the Rocky Road kit or the OME kit installed.
You mentioned that the rocky road kit is a whole lot cheaper, well, you generally get what you pay for.
I can tell you that I'm very happy with the Rough Country 2 inch spacer lift, which I have been running for about 3 years now.
