1.5" or 1.75" spacers?

Hi Guys, so I'm gearing up for mods once my Rubi arrives and I'm looking into wheel spacers for my Moab factory rims and I'm wondering if I should purchase the 1.75" spacers or if 1.5" should be fine?


What I plan to run:

'14 JKUR
35x12.5x17 KM2s on factory Jeep Moab rims (6.25 backspacing)
2.5" TF spring lift.

Now I know I have seen other Jeeps running factory rims with 1.5" spacers, however I've always wondering why lift companies recommend 4.5" of back spacing on aftermarket rims..

To get to 4.5" BS I'd need to run 1.75" spacers (6.25-1.75 = 4.5)

So my question is.. Obviously people are running 1.5".. Is this the best set up or would I be better off with 1.75"?

My guess is that as long as 1.5" won't rub at all, it may be best because I'm thinking 1.75 may push the tire out a bit more likely resulting in rub in the rear fender under flex?

I'm about to order spacers and some other goodies soon, so I would really appreciate some feedback..

You should be fine either way. But he's a thought....buy aftermarket wheels too then sell your stockers complete and you will recoup a lot of your money from the AM wheels and tires.

I like the look of the Moab's and have just plastidipped them. I think they will look sharp with Billet.

I picked the tires and rims up off Kijjiji (like CL) for $300 and sold the tires for $100.
I have about 60$ worth of dip into them so for $260 for Moabs dipped black I think I'm a head a bit over buying new rims (and I prefer the style of the Moabs over solid steels). For what I have into the Moabs, I'm willing to spend another $200 for spacers.. Just not sure which to buy..?

Thanks

4.5" is just a benchmark. If you run wheels w/4.75" bs, you should be fine, depending on the tire width.

I think the KM2's are 12" wide...right? Wrong? If so, you'd be okay.

I'm looking at running 35x12.5x17 km2s.

Do you guys think running 1.75" spacers on the TF 2.5" spring lift will push the tires out too much in the rear and into the flare under flex?

Thanks again guys

Nope. Spacers will push your wheels out from the frame, period. Shouldn't have an issue with the flares, stock or otherwise, unless you're looking at extreme tire movement.

I'm basing this on your use of the word "flex," which indicates to me that you're gonna do more with your rig than just standard wheeling. If that's the case, you might need to trim your pinch seams, depending on your YM (IIRC, '13s and up have been factory trimmed).
