Do you have a link to the JK pattern hub conversion? I've been looking for one for awhile and haven't run across one.
Running JK 17" wheels with 35" tires - setups requested

Oh,must be wrong,I thought if I got the Yukon free spin kit,and wanted the bigger (non ranger style lockout)i would have to change to the jk pattern up front?
Yukon makes 2 conversions that fit the TJ knuckle. WU-07 and WU-08. 5 on 4.5 and 5 on 5.5. I've had reason to use a 5 on 5 hub conversion and gave up looking a year ago when I didn't see one anywhere.
I have 1.5" all around, so I can say for certain they clear. The OEM rear wheel studs were way too short for spacers. I had to install Dorman 610-449 wheel studs on the rear... 1-15/16" long, which I think are the same length as the fronts.
Might be worth noting that in order to install the longer studs, you do have to pull the rear axle out a bit to feed them into the holes. Or at least I did. once they're in its not too bad, but a stud install tool helps a lot.
Yeah, but the degree of pull-out you're describing will still lock you into child support payments if employed elsewhere in life. Barely a pull-out. More like a half-assed withdrawal and a nudge to one side.
Let's hear the myth you've heard about them that makes you cringe. Did you torque yours to 30 ft lbs and all of your wheels fell off?
p.s. @John Cooper knows a guy that blamed it on a duck

Let's not pick on @AndyG for this. He blamed the duck because he forgot he had one of his employees do a tire rotation.

My guys think a rotation happens when the wheels roll.
Last year they installed a skylight….the people in the apartment above went ballistic.
You might have missed the point. That spacer is on the truck from the factory on the front unit bearings.
Im looking at a 17x9” rim with -12mm offset, which looks to be ~4.5” backspacing.
What width spacer am I looking at needing here? Tires will be 35x17x12.5 if that matters. Or is -12mm offset + a spacer going to create problems?
I don't know offset. 4" of backspacing is a good number to work towards for a 35x12.5
Problem is it already has 4” of backspacing so it’s going to be more? Less? Once I add the spacers to correct the bolt pattern.
Backspacing is a measurment from the hub mounting surface to the back of the wheel. Imagine or place the spacer in the wheel. Adding a spacer is moving the hub mounting surface closer to the back of the wheel.
This site is invaluable for visualizing this stuff. I'm using it to figure out what I need in a spare carrier, too.
You'll need to enter tire sizes & offset... offset being a proxy for wheel width & backspacing. Tire clearance is what you're ultimately concerned with anyway. When I was considering 35s, I entered the specs and then figured out what spacer thickness got me closest to OE inner sidewall clearance to ensure I wouldn't rub.
That tool is fantastic, thanks.
do we know what the OEM specs for tire size/wheel backspacing/offset?
With a larger tire, we do not care about OEM specs or replicating those specific measurements. We are more interested in the steering axis inclination and where the center of the tire contact patch rotates relative to the SAI.
