Why all 8 arms?

[Jkohler]

I'm running 8.5 with 5.0 backspace wheels with my game-changer and 37's. No problems so far but I'm not running the front shock relocation bracket. I make put one on and see what it looks like before long.

Thanks @Namib What interferes? Is it the front relocation brackets? Or the rear sway bar link? In doing some research, it seems I may be able to run 5.2 backspace if I don't install the front shock relocation brackets and if I use a drop bracket on the rear sway bar (instead of a longer links). It's a bit confusing, especially since MetalCloak's website asks if your wheels are more or less than 5.5" backspacing. 5.2 is less than 5.5, but may still cause issues.
Thanks again!

Agree it is confusing... I changed wheels when I did the lift so I never tried to find out where it rubs. I believe the rear is the problem... https://www.jlwranglerforums.com/forum/threads/ideal-offset-backspacing-jl.4270/

Good to know. Let us know if you install the front shock brackets. Thanks.
Is this on a Rubicon?
Did you use longer links in the rear or a sway bar drop bracket?

 

[Jkohler]

It is a Rubicon. There kit came with longer links and a 1” spacer drop as well

@ExitLeft , you've got for sure... Time will tell... these new axles are better than the JK axles which seemed to come apart if they just looked at 37s :cwl:. Ok, maybe not that bad, but not that far off.

We've had 37s under the bosses JLUR since February and so far everything has been holding up. I believe it has more than 8K miles on it. Admittedly it's not getting wheeled every weekend, but when it does get wheeled, the boss isn't afraid to use it.

My comment was more saying that you didn't need to 3.5" for 37s, the 2.5" is fine. So go 2.5" and 35s until you feel you're wanting to go bigger and if you do, your JL can fit them!

How about sport Jl on 35s ? any issues there possibly, my off road driving is beach, sand dunes, fire trails, gravel, and mainly daily drivign

The Sport front axle is the Dana M186 (aka Dana 30) and is really at it's limit with 35s. However, for your intended usage, you'll probably be fine.

There are a lot of people running the M186 with 35s on the street and mild wheeling and not having problems. It's when they really start pushing it off road is when they start seeing problems.

There are a ton of high performance parts to make the M186 stronger, but we really caution weighing all the options. Swapping in a factory Rubicon M210 front axle or upgrading to an aftermarket Dana 44 front axle is much better solution.

The rear axle handle 35s no problem.

Hey guys I’m new, quick question I noticed this thread is a few years old, I was wondering if the stock rubicon axles have proved to be good with 37’s overtime?

The general consensus is yes. A few guys have broken them, but all the ones I've read were either really bound up in the rocks or with a lot of skinny pedal and some impact. Impacts at speed will break anything if substantial enough. We've been on 37's for 9 months, 10k miles, about 1,000 off road miles, and several fairly tough trails like Holcomb creek, John bull, and metal masher without an issue.

Thanks for the reply, I do plan on wheeling every other weekend. But before I do any upgrades I want to see what this thing can do stock. But when that day comes 37’s are what I am thinking.

The Sport front axle is the Dana M190 (aka Dana 30) and is really at it's limit with 35s. However, for your intended usage, you'll probably be fine.

The rear axle handle 35s no problem.

If I swap out the front axle, would the back need to be swapped to match?

Just a technicality but there's no such thing as a M190 axle. The non-Rubicon front axle is the M186.

That or re-gear your rear axle (or both if you want a lower ratio) to match.

You are correct, no M190 in the Jeep, there is an M190 in the Ranger and I was just editing some data on Ranger applications, so it just stuck in my head and made it to my post.

Fast fingers on my part, sorry all.

It would be best to swap them both.

The Rubicon axles are 1.5" wider than the Sport/Sahara axles.

As an added bonus the Rubicon rear M220 uses the much larger set 80 wheel bearing with 124% more load carrying capacity and 122% more side load capacity over the set 10 wheel bearing used in the Sport/Sahara axles.

Thank you! What can I do at the lowest cost possible to help improve if needed my sport ride for wash board roads and driving and handling sand dunes? right now my jeep is sitting on rubicon take offs no other mods at all running the 3.6 L Auto 8 speed
