lol yeah bro! Lets do it! I'm so curious. well up travel is going to be hard to measure but we can estimate. What's easy to measure is droop travel. Here is a pic showing 9" from tire to fender and I should be getting between 1" to 2" up into the fender. I know it goes up there bc I've seen a little wear on the felt and to even get the 8.7" of wheel travel Chrystler claims, would mean it would have to. Personally I think Chrysler might be full of shit and there is no way we get 8.7" in front and 10.2" in back stock, especially with sway bars on. Anyways I have 20" rims and I measured 13.75" from rim to fender, measuring from center of wheel straight up. On back, I get 13.75" on one side and 14" on the other. I'm stoked to hear what your droop travel is and should be the same as another guy who measured his who has the OME lift and sway bars on. BC you have your sway bars on I'm pretty sure you will get the same as he did. So that's your droop travel. Then your up travel If you have bigger tires is probably where it hits your fender or wheel well. If you have much less offset than 34mm like me than your tire probably won't even fit in the wheel well meaning your up travel might be the bottom of the fender. That is, without your RRO spacer. With the RRO spacers you can subtract about 2.5" from that. That is a pretty rough estimate on up travel, your tires probably can't even contact the fender if you have the RRO spacer which would make them pretty necessary if your wheels and tires stick out past the fender. Anyways I'd love to hear what you get for droop travel. than remember your now getting 2.5" less up travel bc of the spacers.

In the measurement pics: the longer of the two is the front which shows 13.75" and the shorter is the rear before I put the longer OME shocks on. Now I get about the same as the front and .25" more on one side.

Oh, and one more thing, since you have your sway bars on, you'll get different measurements if you jack up one side of the vehicle versus the whole axle... because the sway bars are limiting articulation.

So, assuming we are just jacking up one side of the Jeep and letting the front and rear drivers side hang/droop, with no other changes Im sitting at 13.75 front and 14.25 rear from center of fender lip to the top center of my 20" wheel.

As far as up travel goes, to get this accurately would require a lot of effort with some jacks, or an articulation ramp. from actual experience wheeling, and vids and pics taken of me while wheeling, I stuff the hell outta my tire (31 offset sir)...but this is about the droop you feel like us rro guys are lacking, which we are clearly not. This is why I dont like opinions, and prefer to prove everything before I put it out there where it can be searched, read, and provide misinformation.

I worked closely with Bilstein when deciding on these, and thats why I brought the information to the forum and social media when I installed them. Just wait til you see whats coming next...stay tuned.
I also did tons of mock ups and measurements to assure I picked the absolute best wheel size and offset, to fit a 33 with absolutely no rubbing, cutting, folding etc. Not sure if you did as well, or you just happened to like a wheel that had the magic offset but I try to spread that word wide and far since so many want to go 0 to +18 offsets and rub like hell (even though it looks good), even on 32s.

Anyway, enough from me for now. Before I take the next step in the suspension, ill get full specs and measurements as is on up and downtravel both with and without (although seriously 99.9% of WK2 guys wont pull sway bar off) the sway bar.

I really don't believe you can do any stuffing with those spacers and sway bars on. If so I'd really like to see it. I can tell you, I have slightly more offset than you and my tires only fit in the fender when the wheels are perfectly straight and its only by millimeters. If you helped Bilstein design the 5100s what were you guys thinking when you made the compression stops PLASTIC!? I broke mine after bottoming out once. The rep at bilstein I spoke to admitted they were good for "One Hit". If your measurements are accurate, I'll believe it when I hear the same thing from a few others. I don't care what the answers are but I'd really like to know. So far I'm basing my expectation off only my measurements and that of one other guy. He had the OME lift which the front struts have almost identical specs to the Bilstein 5100s only like .02" longer at compression. Exactly the same at extension. According to him, He got different measurements when he jacked up one side and then he jacked up the whole front end. He was also getting much less droop travel than me which leads me to believe his sway bars were limiting his travel. Maybe there is another explanation. I won't feel certain about anything until a few more weigh in. I also wouldn't expect tire rub with bigger tires and RRO spacers as I don't believe the tires can even compress high enough with the spacers to rub. You do realize that while lifting the vehicle with RRO spacers you don't gain any up travel. Something which is a major weak spot for stock suspension, very easy to bottom out your suspension. While alternative lifts like ome or bilsteins with tj spacers or Eibach all terrain creates more up travel and mitigates bottoming out issues. So even if we have very similar droop travel measurements, you are still cutting off 2.5" of possible up travel (if you had stock tires). Of course running anything bigger than a stock tire is naturally going to limit up travel because it will hit your wheel well so in that case the spacer may only cause you to loose 2.5" minus whatever you have already lost by having an oversized tire. I know that because I have 31.8" tires and they can impact the wheel well which is one reason I went to longer shocks and added trim packers to the front, to mitigate my tires hitting the wheel well at full compression. I don't know how much wheel travel I've lost by running tires that have radius of .65" more than stock but I would guess it would be less than .65" because I doubt the vehicle was designed so that stock tires would impact the wheel wells at full compression. So I'm just saying from where I'm standing, it looks like you do loose potential wheel travel with the RRO spacers. I'm just not sure how much and you can't really increase up travel other than the .4" you get on the front if you run the Bilsteins with them.

Re: RRO 2.5" lift + Bilstein 5100(front)

Bro I just looked at your webpage and you said the RRO spacer lift gives 2.5" up front and .5" in back. Talk about putting bad info on the internet lol

Not getting into the current debate, but these pics are the final result after going back to the first notch... Ride is a bit smoother on the lower setting. Everything has settled in now and the ride is great, perfect combo of stiffness added while maintaining the smooth ride... Currently running @ 45 psi..

Everyone comments on how "tough" the Jeep looks now...and it doesn't feel like a "grocery getter" anymore... Looking forward to hitting some trails...

Re: RRO 2.5" lift + Bilstein 5100(front)

Looks great. Are those KO2's and if so what size with the lift? I'm looking at a similar setup. Though I might keep the load levelers in the back.

Re: RRO 2.5" lift + Bilstein 5100(front)

Chritaka, how does your mileage/power compare pre/post ko2s? They add almost 20lbs in rotating mass per corner...my only hold up with the ko2's.

Re: RRO 2.5" lift + Bilstein 5100(front)

I know you didn't ask me but I'll share since I have the same tires. I got like 19mpg driving through town going home after install! I usually got between 17-18. I still get about that, maybe .5 -1mpg less in city and maybe 2mpg less on highway but I also lifted the vehicle bit. Not much difference. They looked really good before I even lifted. I honestly liked it just as much not lifted or even leveled. It looked great with 20" and an aggressive tire but would bottom out easily and I didn't have much ground clearance so I lifted it. Yeah the tires are great! Get them!

Actually these 285/55r20 tires are 55.6 lbs, which is a actually on par or lighter than other mfg in this size, and the wheels are 28 lbs... The wheels are the lightest ones I found for a forged, etc and being hub centric was a bonus. The low wheel weight helps offset the larger tire weight. My combo is 15.6 lbs heavier than stock. I actually didn't go with 305/55r20 (33x12.50) as they were 5.1 lbs heavier, though they should fit without issue.

With all those calcs and research I still ended up losing ~2.5 mpg on avg, staying between 17.6-18 mpg avg with probably 60% hwy. Pure hwy, I do 21.5-22 mpg @ 70-75 mph. I had removed the air dam "wings" also and I can tell I catch a good bit more air.

I don't feel like I lost much power, a little off the line, but it doesn't struggle at all. I haven't noticed much difference in shift points and it will still move to pass slow pokes.

All that being said, I still think it's worth it...looks so much better in person too...pics don't do it justice.

Thanks for the insight, since I picked up the 75th anniversary planning on keeping the stock wheels. I'm between the terragrapplers and the ko2's. The terragrapplers add approx 10 lbs per corner, where as I mentioned 20 lbs per corner with the ko2's in 275/55/20. I must admit the ko2's look much better...

Re: RRO 2.5" lift + Bilstein 5100(front)

Just read this whole thread. I see grandcherokee3720 is throwing out his usual "let me throw in my two cents how I disconnected my swaybars" haha. I also. Noticed how high PSI everyone is running in their tires. I think you're giving yourself a much tougher ride, worse wear, and more highway wandering. I chalk tested mine and 35psi was the best. Drives awesome too. Love your build alludc, wish I had the balls to go that big!
