I installed the Rancho kit without extra parts and am happy with it. The alignment showed 3.5 degrees caster. I asked the tech if I should consider getting longer lower control arms or geo brackets to increase the caster angle. He recommended against adding them as they would change the angle between the front drive shaft and differential and increase wear.

Love to see pics of your ride.

What tech is this? Does he understand that by installing the lift he changed the angle? The angle changed in two ways; One, the Jeep sits higher so the angle for the drive shaft is steeper. Two, the same forces that rotated your axle and reduced your castor changed the angle that the axle housing is in relation to the drive shaft.

Don't get me wrong, if you are happy with the way it drives don't change a thing. It just scares me a little when I hear people who should understand this better than I do show that they don't.

There would be a lot less traffic here if it weren't for "tech's" like his.

Rancho 2" Sport Lift on mine for three months now. Wondering where the 5000 is relative to the 9000 in feel, midland setting?
I enjoyed the ride right off the lift.

Totally based on what I've heard others here say, because I'm running the XL9000's, but what I've heard is that the 9000 on setting 5 is roughly equivalent in damping as the 5000. Again, I don't think I've seen Matt @Rancho verify this.

So I had initially planned to switch to 295/70/17s at some point after the lift, but really like the look and feel of the 285/70/17s I have now (MT Deegan 38 A/Ts). Problem is I had installed the front bumpstops but now wondering what to do...is there any way to remove without pulling the springs or is the 2” loss of flex not too bad?

If I were you I'd pull the bump stops, no reason to limit travel if you don't have to. Unfortunately I don't see any way of getting them out that's gonna be less of a pain than pulling the springs.

Am I thinking right that even at 295/70/17 the bump stops aren't needed? I was thinking that 0.3" radius difference vs 285/70/17 wouldn't need the bump stop.

It was either 295 or 285/75/70 I was initially considering.

Thought that would be the case thanks ...maybe IÂ’ll reconsider the larger tires.

I added full 2" (Metalcloak) of rear bump stop to keep 285/75R17's from rubbing. With only 1" in I still got rubbing on fender at full stuff.

Is anyone running flat fenders with this kit yet?

@4Jeepn is running the Bushwacker flats and 35s. Rancho also posted a few pics early in this thread of someone running Moab with flats and 35s.

I also plan to move to flats at some point in the future, just not sure when.

hmmm
285/75R17s
2" frt bump stops
1"rear bump stops
not only no rubs at full squat on the stops ...
but I even have room for 35" rubber.

with the clearance I have ,in theory I could half my stops front and back with 34" tires and still not rub.

could this all be the result of wheel back space differences?

What back spacing are you running?
I keep getting hung up on 285/70/17 being only .516" less radius than 285/70/17 and .85" radius less than 315/70/17. Throwing on 2" spacers seems like overkill! Obviously I"m ignoring rubber width on the 35's, but still. People run 285/70/17 all the time with spacers and no lift. With 2" rancho lift, added the 285/75/17 diameter seems like it should clear easily.

285 is the width, as in 285 millimeters.

Thanks, I've got that part, I just left off the aspect ratio that went with it there that would have tied the height back in!

since i'm in Pa, I by law have to keep my rubber inside the fenders.
i'm running rims with 5.2" of backspace .
even with a 11.5" wide tire(285/75R17) all my rubber is up in the fender wheel well when I fully squat it.
if I stick my hand up in there and feel around I have clearance of at least an inch all the way around on every wheel.

I was curious how they would be as my aev are 5.2 also. The other guy has Method NV which are 4.75. Weird

its a .45 difference in BS between the two rims
close enough to call a 1/2 inch.
i'd imagine 4.50 back space could cause more problems
as the closer you set the tire to the fender edge , the less wheel well is usable

I recently got 285/75R17s on quadratec hardrock wheels with no lift or added bumpstops. When I flexed it, the rear tire rubbed the front part of the rear flare, a few inches above the rubicon rail. The front tire was grabbing a piece of plastic on the front underside of the flare. I think I'm going to do some fender trimming and try not to add any bumpstop. Can you get these springs separate yet? I'm considering the 2 inch mopar coils because they're cheap and I don't really need another set of shocks.

@jadmt seems very happy with just the mopar coils. And he seems to be a reliable source of good info. He has me considering those coils as well, it is hard to not give them a try at that price.

That seems quite likely. The 5.2 with 285/75 is an awesome combo. For some people, its not going to have a "stance", for others and functionally? A home run.

I don't want to mess up a Rancho thread but very impressed after a trip to the coast and back.

So, repost of my numbers here
Just received my rancho adjustable LCA’s. I know I need to have the toe adjusted as well, but this particular question has to do with the LCAs. Can someone give me an idea of how long they should be set to and where the measurements should be taken (ie end to end or center hole to center hole).
Thanks guys. I’ll probably put them on Friday night and try to be the first guy at the alignment shop Saturday morning.
